Numbers 32 Summary and Study Guide

Moses said “be sure your sin will find you out” to two whole tribes, and the sin he had in mind was staying home from a war. This Numbers 32 summary and study guide covers that Bible chapter, where Reuben and Gad ask Moses to let them stay on the near side of the Jordan and he answers with a condition.

Setting the Stage

God promised Abraham that his descendants would be given a country of their own (Genesis 12:7). Israel reached its southern border, refused to go in, and God answered that every adult who refused would die in the desert while their children went in instead (Numbers 14:29-31).

Forty years later that second generation is camped on the plains of Moab with one river left to cross. On the way they beat two kings, Sihon and Og, and took their land (Numbers 21:21-35), and they have just divided an enormous herd of captured livestock (Numbers 31:32-33). Moses has been told he will not cross, and Joshua has been appointed to lead in his place (Numbers 27:12-23). Numbers 32 opens with two tribes looking at the pasture on the near bank.

Comprehensive Numbers 32 Summary

Reuben and Gad own more livestock than they can pasture, and the country Israel has just taken east of the Jordan is made for it. They bring a request to Moses, Eleazar the priest and the leaders of the nation. They name nine towns in that region and ask to be given it instead of a share across the river.

Moses hears the last line of the request, “bring us not over Jordan,” as desertion. He asks whether the rest of Israel is to go to war while these two tribes sit still, then spends eight verses on the reason he is alarmed. Forty years earlier the spies came back from that same border, talked the nation out of going in, and cost them everything. Moses tells these men they are starting it again.

They come closer and make an offer. They will build pens for the livestock and fortified towns for their families here, then arm themselves and march at the head of the army, and they will not go home until every other tribe has its land.

Moses accepts on terms. If they cross armed and stay until the fighting is finished, the eastern land is theirs and nobody can hold anything against them. If they do not, they have sinned against God, and their sin will find them out. He tells them to build, and to do what they have said.

The tribes agree. Moses then puts the arrangement in front of Eleazar, Joshua and the heads of the tribes, and writes the forfeit into it. He hands over the old kingdoms of Sihon and Og to Reuben, Gad and half the tribe of Manasseh, who were never part of the negotiation. The chapter closes with towns rebuilt and renamed, and with three Manassite captains who go out and take more.

One Word Summary

• Conditions: the land is granted only inside a set of ifs
• Vanguard: the position the two tribes offered to take
• Sheepfolds: what they built here, and what Israel later remembered them for

In One Sentence

Two tribes ask Moses for the grazing land east of the Jordan, and he grants it on one condition, that their fighting men cross the river first and stay in the field until every other tribe has received its inheritance.

Theme of Numbers 32

Numbers 32 is about an inheritance held on terms. The land is real and God has already handed it over, and the handing over still rests on a promise to fight a war the men making the promise will gain nothing from.

Two ideas run alongside that one. Refusing to help is itself sin, which is what Moses names in verse 23 and what James 4:17 states plainly. And taking the heart out of other believers is a real injury, serious enough that Moses puts it in the same sentence as the disaster at Kadesh.

The Agreement in Numbers 32

Most of this chapter is one negotiation, and it is built the way a binding agreement is built.

Moses names witnesses because he will not be alive to enforce anything. He dies before Israel crosses, and Eleazar and Joshua are the ones who see the agreement through.

Joshua 4:12-13 says the eastern tribes “passed over armed before the children of Israel, as Moses spake unto them,” about forty thousand of them, and they went ahead of the nation into the fighting.

Years later Joshua called them together and gave his verdict: “Ye have kept all that Moses the servant of the LORD commanded you, and have obeyed my voice in all that I commanded you: ye have not left your brethren these many days unto this day” (Joshua 22:2-3). Joshua is telling them they did everything Moses required and stayed with the other tribes the whole time. The promise made in Numbers 32 was kept.

Observations from Numbers 32

Moses Changes Who They Are Marching In Front Of (vv.17, 20-22, 27, 32)

When the two tribes make their offer, they say they will go armed “before the children of Israel” (v.17). That wording puts the service on the level of one tribe helping another. Moses answers using a different phrase, “before the LORD” (vv.20-22), and from that point on the tribes use his wording instead of their own (vv.27, 32).

The phrase “before the LORD” falls in six verses of this chapter (20, 21, 22, 27, 29, 32), eight times in all, because verse 22 uses it three times over. Every one of them comes after Moses first says it. In his wording all of them are serving God, and that is the ground the agreement finally rests on.

Reuben Is Named First Once, and Never Again (vv.1, 2, 6, 25, 29, 31, 33)

Verse 1 has “the children of Reuben and the children of Gad.” Every later verse that names them both reverses the order and puts Gad first. Reuben was the firstborn son of Jacob, and Jacob’s blessing had already said of him, “Unstable as water, thou shalt not excel” (Genesis 49:4).

Jacob told his firstborn he would come second. From verse 2 of this chapter onward, in the record of the tribe’s own negotiation, that is where Reuben stands.

The Words for Owning and the Words for Fighting Fall in Seven Verses Each

The language of possession and inheritance appears in seven verses of this chapter (5, 18, 19, 22, 29, 30, 32). The word “armed” appears in seven verses too (17, 20, 21, 27, 29, 30, 32). Three verses carry both at once (29, 30, 32).

The chapter never lets the land be discussed for long without the war coming back into the sentence. Moses makes that point out loud in verse 6, and it stays true of every later verse that mentions the land.

They Say Sheepfolds, Moses Says It Back, and Gad Builds Them (vv.16, 24, 36)

The two tribes propose “sheepfolds here for our cattle, and cities for our little ones” (v.16). Moses gives permission using the same two items in reverse: “Build you cities for your little ones, and folds for your sheep” (v.24). The record of what Gad actually built ends with “fenced cities: and folds for sheep” (v.36). What they asked for, what they were allowed, and what they made are the same two things three times over.

Generations later, in the days of the judges, Deborah’s song asks Reuben a question built on that same word: “Why abodest thou among the sheepfolds, to hear the bleatings of the flocks?” (Judges 5:16). Deborah is asking why Reuben stayed home with the animals while Israel went to war, and she reaches for the very word Reuben had used here to ask it.

The Chapter Runs on the Word “Until” (vv.13, 17, 18, 21)

“Until” appears four times in Numbers 32, and the first one is a sentence of judgment. God made Israel wander forty years “until all the generation, that had done evil in the sight of the LORD, was consumed” (v.13), which is to say until the guilty generation had died out.

The other three uses are the commitments made in this chapter. The two tribes will fight “until we have brought them unto their place” (v.17), they will stay away from home “until the children of Israel have inherited every man his inheritance” (v.18), and Moses requires them across the river “until he hath driven out his enemies from before him” (v.21). None of the three had a date on it. The word that measured a punishment now measures a service, and the two tribes agreed without knowing how long it would run.

Difficult Verses Explained

What Does “Be Sure Your Sin Will Find You Out” Mean?

It means the sin itself will come after them, not that somebody will discover what they did. The Hebrew of Numbers 32:23 reads more like “know your sin, that it will find you out,” and older commentators such as Albert Barnes and the Pulpit Commentary read it the same way: the wrong brings its own consequence along with it. Moses is telling two tribes that if they break this agreement, the damage will come looking for them.

Does Numbers 32:23 Mean Every Sin Is Exposed in This Life?

The verse makes a narrower claim than that. Moses spoke it to two tribes about one agreement he was warning them to keep, so it stands as a warning inside that setting rather than as a rule covering all wrongdoing everywhere. Jesus does say that everything hidden will be made known (Luke 12:2), and the setting He gives for that is the day of judgment rather than this life. Some sin comes to light here, some waits, and the reckoning Scripture guarantees is God’s, in His time.

What Does Moses Mean by “Discourage” in Verse 7?

He means turning Israel away from something they had been told to do. “Wherefore discourage ye the heart of the children of Israel from going over into the land which the LORD hath given them?” (Numbers 32:7). The Hebrew word behind “discourage” is the same one used two chapters earlier for a father or husband who cancels a woman’s vow: “if her father disallow her” (Numbers 30:5), “if her husband disallowed her” (Numbers 30:8). Moses is charging the two tribes with cancelling Israel’s will to cross, not merely with lowering the national mood.

Why Is Moses So Angry at What Sounds Like a Reasonable Request?

Because of what these two tribes were worth on a battlefield. The census a few chapters earlier counted 43,730 fighting men in Reuben and 40,500 in Gad (Numbers 26:7, 18), out of the 601,730 Israel had counted in all (Numbers 26:51). The two tribes asking to stay were about one soldier in seven. Moses had already watched ten men talk the whole nation out of going in (Numbers 13:31-33), and two tribes doing it would be worse.

Where Does Half the Tribe of Manasseh Come From?

They appear for the first time in verse 33 without having asked for anything, and verse 39 explains why. The family of Machir had already gone into Gilead, driven out the Amorites and taken it. Moses gave them the ground they had won rather than moving them off it, which is how a third group ended up settled east of the Jordan.

Why Were the Names of the Cities Changed?

Two of the towns Reuben rebuilt carried the names of foreign gods. Isaiah names Nebo as an idol of Babylon (Isaiah 46:1), and Baal-meon carries the name of Baal, while God had told Israel, “make no mention of the name of other gods, neither let it be heard out of thy mouth” (Exodus 23:13). Renaming the towns fits that command, and it is the reading most Bible teachers take. Later Jewish commentators, including Nahmanides, argued instead that Israel was restoring older names the Amorites had replaced, so Scripture leaves the reason unsettled.

Common Misunderstandings

• That the two tribes broke their promise. Joshua, the man Moses appointed to enforce the agreement, told them afterwards that they had kept everything Moses commanded and had not left the other tribes (Joshua 22:2-3).
• That the forty thousand who crossed prove they cheated. Moses himself told them to build fortified towns for their families (v.24) and repeated the arrangement approvingly later, telling them their wives, children and livestock would stay behind (Deuteronomy 3:19). A garrison at home was part of the deal, not a breach of it.
• That they asked to settle outside the promised land. The territory God pledged to Abraham reached beyond the Jordan, and Numbers 32 never charges them with leaving it. The one thing Moses calls sin is abandoning the war (v.23).
• That “your sin will find you out” was said to one person about a private failure. Moses said it to two tribes about a public military commitment.
• That the Gadarenes of Mark 5 were descendants of the tribe of Gad. Gadara did stand in this general region, and Scripture never traces those first-century townspeople back to Gad. The link is a preacher’s guess rather than something the Bible states.

Christ Connection

The strongest line from this chapter to Christ runs through one sentence the two tribes said out loud: “We will not return unto our houses, until the children of Israel have inherited every man his inheritance” (Numbers 32:18). They were promising that they would not take their own rest until everybody else had theirs. Their families would sleep in fortified towns and their fighting men would sleep in the field, for as long as it took.

Scripture makes exactly that solidarity a matter of the gospel. Hebrews 4:8-9 says that Joshua did not finally give Israel its rest, and the King James prints his name there as Jesus, the Greek form of Joshua: “there remaineth therefore a rest to the people of God,” and Hebrews 11:40 says of every believer who died before Christ came that God “provided some better thing for us, that they without us should not be made perfect.”

Nobody arrives alone. What Reuben and Gad promised for one campaign, God has arranged for the whole family He is saving.

The chapter opens onto Christ at several other points:

• Going in front. The two tribes offered to march at the head of the army so the others could reach their land, and Joshua 6:13 records armed men going before the ark at Jericho. Hebrews 6:20 uses the same picture of Jesus, “whither the forerunner is for us entered.”
• Guiltless before the LORD. Moses could promise that standing only if the tribes performed everything (v.22). Colossians 1:22 says Christ presents believers “holy and unblameable and unreproveable in his sight,” which is the same clearance resting on someone else’s performance.
• A word that has to be kept. Verse 24 binds these men to their own mouths, and Numbers 30:2 says the same of anyone who makes a vow. Every promise God has made is kept in Christ instead: “all the promises of God in him are yea, and in him Amen” (2 Corinthians 1:20).
• The warning of verse 23, answered. Moses states the problem and stops there. The remedy comes later: “If we confess our sins, he is faithful and just to forgive us our sins” (1 John 1:9), and “there is therefore now no condemnation to them which are in Christ Jesus” (Romans 8:1).
• Refuge on both sides of the river. God set aside three cities of refuge east of the Jordan and three in Canaan (Numbers 35:14). Even the tribes who settled on the far bank were given a place to run to, which pictures the shelter believers are told to flee to in Hebrews 6:18.

When, Where, and Why

• When: The fortieth year after Israel left Egypt, in the last weeks of Moses’ life. He has already been told he will not enter the land and has already appointed Joshua (Numbers 27:12-23), which is why this chapter is so careful about who will enforce the agreement after him.
• Where: The plains of Moab, with the camp east of the Jordan opposite Jericho (Numbers 26:63; 31:12). The territory under discussion had belonged to Sihon and Og, hill country and open pasture reaching north from the river Arnon. It was well watered and good for herds, which is exactly what verse 1 says the two tribes noticed about it. Dibon, the first town Gad rebuilt, is where the Moabite Stone was dug up in 1868, carrying an inscription of a later Moabite king who took the region back.
• Why: Moses is settling the last things that will outlive him. The book of Numbers has been building toward a nation crossing into its land together, and a request to divide that crossing had to be answered before he died. He records the terms, the witnesses and the forfeit so that nothing afterwards depends on his memory or his presence.

Key Verses

“And Moses said unto the children of Gad and to the children of Reuben, Shall your brethren go to war, and shall ye sit here?”

Numbers 32:6

Moses is asking whether the rest of the nation, the men he calls “your brethren,” should do the fighting while these two tribes stay where they are. It is the question the whole chapter answers, and everything the two tribes say afterwards is an attempt to answer it.

“We will not return unto our houses, until the children of Israel have inherited every man his inheritance.”

Numbers 32:18

They are promising to stay in the field until the last tribe has been settled. It is the part of the offer Moses answers, and after it he sets terms rather than refusing.

“And the land be subdued before the LORD: then afterward ye shall return, and be guiltless before the LORD, and before Israel; and this land shall be your possession before the LORD.”

Numbers 32:22

Once the fighting is over, Moses says, they may go home clear of any charge from God or from the nation, and the land will be theirs. Both the land and the clean record wait on the work being finished.

“Build you cities for your little ones, and folds for your sheep; and do that which hath proceeded out of your mouth.”

Numbers 32:24

Moses tells them to go ahead and build, and to do what they have just promised. The last phrase is the wording God uses for vows in Numbers 30:2, so Moses is treating their offer as something God now holds them to.

Key Lessons from Numbers 32

• Refusing to take part in work God has given His people can itself be sin, which is what Moses calls it in verse 23 and what James 4:17 says plainly.
• A promise made in front of God is measured by what gets done, since Moses answered their offer by telling them to perform what came out of their mouths (v.24).
• Discouraging God’s people does real damage, which is why Moses set this request beside the report that cost Israel forty years (vv.7-9).
• An arrangement meant to outlast the person who made it needs named witnesses and written terms, which is why Moses brought in Eleazar and Joshua (v.28).
• What is built for safety can become the thing a person is known for hiding behind, as Reuben’s sheepfolds were (v.16; Judges 5:16).
• God gave these tribes the land they asked for, and the land carried an exposure that never came up in the negotiation (1 Chronicles 5:26).

Bible Study Questions

1. Moses says the request is discouraging Israel (v.7) before the two tribes have explained themselves. What does the rest of the chapter show about whether he read them correctly?
2. What exactly did Reuben and Gad offer in verses 16 to 19, and which part of that offer costs them the most?
3. Moses says “before the children of Israel” becomes “before the LORD” between verse 17 and verse 20. What difference does that change make to what the two tribes were agreeing to?
4. Verse 23 says “be sure your sin will find you out.” How does the setting of that sentence change the way you have heard it quoted?
5. Read Joshua 22:1-6 alongside this chapter. What does Joshua’s verdict add to your reading of Numbers 32?
6. Verse 28 names Eleazar and Joshua as witnesses. Where in your own commitments would naming someone else make the difference between an intention and a promise?
7. The two tribes agreed to stay in the field for as long as the war took, without knowing how long that was. What does that ask of anyone who serves God today?

1 Now the children of Reuben and the children of Gad had a very great multitude of cattle: and when they saw the land of Jazer, and the land of Gilead, that, behold, the place was a place for cattle;

2 The children of Gad and the children of Reuben came and spake unto Moses, and to Eleazar the priest, and unto the princes of the congregation, saying,

3 Ataroth, and Dibon, and Jazer, and Nimrah, and Heshbon, and Elealeh, and Shebam, and Nebo, and Beon,

4 Even the country which the LORD smote before the congregation of Israel, is a land for cattle, and thy servants have cattle:

5 Wherefore, said they, if we have found grace in thy sight, let this land be given unto thy servants for a possession, and bring us not over Jordan.

6 And Moses said unto the children of Gad and to the children of Reuben, Shall your brethren go to war, and shall ye sit here?

7 And wherefore discourage ye the heart of the children of Israel from going over into the land which the LORD hath given them?

8 Thus did your fathers, when I sent them from Kadesh-barnea to see the land.

9 For when they went up unto the valley of Eshcol, and saw the land, they discouraged the heart of the children of Israel, that they should not go into the land which the LORD had given them.

10 And the LORD’S anger was kindled the same time, and he sware, saying,

11 Surely none of the men that came up out of Egypt, from twenty years old and upward, shall see the land which I sware unto Abraham, unto Isaac, and unto Jacob; because they have not wholly followed me:

12 Save Caleb the son of Jephunneh the Kenezite, and Joshua the son of Nun: for they have wholly followed the LORD.

13 And the LORD’S anger was kindled against Israel, and he made them wander in the wilderness forty years, until all the generation, that had done evil in the sight of the LORD, was consumed.

14 And, behold, ye are risen up in your fathers’ stead, an increase of sinful men, to augment yet the fierce anger of the LORD toward Israel.

15 For if ye turn away from after him, he will yet again leave them in the wilderness; and ye shall destroy all this people.

16 And they came near unto him, and said, We will build sheepfolds here for our cattle, and cities for our little ones:

17 But we ourselves will go ready armed before the children of Israel, until we have brought them unto their place: and our little ones shall dwell in the fenced cities because of the inhabitants of the land.

18 We will not return unto our houses, until the children of Israel have inherited every man his inheritance.

19 For we will not inherit with them on yonder side Jordan, or forward; because our inheritance is fallen to us on this side Jordan eastward.

20 And Moses said unto them, If ye will do this thing, if ye will go armed before the LORD to war,

21 And will go all of you armed over Jordan before the LORD, until he hath driven out his enemies from before him,

22 And the land be subdued before the LORD: then afterward ye shall return, and be guiltless before the LORD, and before Israel; and this land shall be your possession before the LORD.

23 But if ye will not do so, behold, ye have sinned against the LORD: and be sure your sin will find you out.

24 Build you cities for your little ones, and folds for your sheep; and do that which hath proceeded out of your mouth.

25 And the children of Gad and the children of Reuben spake unto Moses, saying, Thy servants will do as my lord commandeth.

26 Our little ones, our wives, our flocks, and all our cattle, shall be there in the cities of Gilead:

27 But thy servants will pass over, every man armed for war, before the LORD to battle, as my lord saith.

28 So concerning them Moses commanded Eleazar the priest, and Joshua the son of Nun, and the chief fathers of the tribes of the children of Israel:

29 And Moses said unto them, If the children of Gad and the children of Reuben will pass with you over Jordan, every man armed to battle, before the LORD, and the land shall be subdued before you; then ye shall give them the land of Gilead for a possession:

30 But if they will not pass over with you armed, they shall have possessions among you in the land of Canaan.

31 And the children of Gad and the children of Reuben answered, saying, As the LORD hath said unto thy servants, so will we do.

32 We will pass over armed before the LORD into the land of Canaan, that the possession of our inheritance on this side Jordan may be ours.

33 And Moses gave unto them, even to the children of Gad, and to the children of Reuben, and unto half the tribe of Manasseh the son of Joseph, the kingdom of Sihon king of the Amorites, and the kingdom of Og king of Bashan, the land, with the cities thereof in the coasts, even the cities of the country round about.

34 And the children of Gad built Dibon, and Ataroth, and Aroer,

35 And Atroth, Shophan, and Jaazer, and Jogbehah,

36 And Beth-nimrah, and Beth-haran, fenced cities: and folds for sheep.

37 And the children of Reuben built Heshbon, and Elealeh, and Kirjathaim,

38 And Nebo, and Baal-meon, (their names being changed,) and Shibmah: and gave other names unto the cities which they builded.

39 And the children of Machir the son of Manasseh went to Gilead, and took it, and dispossessed the Amorite which was in it.

40 And Moses gave Gilead unto Machir the son of Manasseh; and he dwelt therein.

41 And Jair the son of Manasseh went and took the small towns thereof, and called them Havoth-jair.

42 And Nobah went and took Kenath, and the villages thereof, and called it Nobah, after his own name.
