Deuteronomy 21 Summary and Study Guide

Deuteronomy 21 sets five laws side by side that look unrelated, and one thread runs through all of them. This Deuteronomy 21 summary and study guide follows that thread from a body found in an open field to a body taken down from a tree before sunset.

Setting the Stage

God promised Abraham a land, and four hundred years later Israel came out of Egypt to go and take it. Forty years after that, they are camped on the plains of Moab, across the Jordan River from Jericho, while Moses lays out the law they will live by once they cross.

Two chapters earlier, Moses dealt with a murderer who is caught and a court that has to weigh what witnesses say. The chapter just before this one dealt with war. Deuteronomy 21 takes up what both of those leave open: what happens when the killer is never found, and what happens to the people a war leaves at someone else’s mercy. You can read the whole chapter here: Deuteronomy 21 (KJV).

Comprehensive Deuteronomy 21 Summary

Deuteronomy 21 gathers five laws for life in the land, and each one puts a name on a responsibility that could easily have gone unclaimed.

It opens with a body lying in open country, killed by a hand the town cannot name. The elders and judges measure from the body to the surrounding towns, and the nearest town carries the case. Its elders take a young cow that has never been worked, break its neck in an unploughed valley with running water, wash their hands over it before the priests, swear their innocence of the killing, and ask God to spare the nation the guilt of blood shed at its door.

The law after it follows a soldier home from a distant war. He has seen a woman among the captives and wants to marry her.

He must bring her into his house, let her shave her head, change out of what she was wearing when she was taken, and mourn her father and mother for a full month before he may go near her. Then she is his wife. If he later changes his mind, he must set her free, and may never sell her.

Next comes a father dividing his estate. Where two wives have borne him sons and he prefers one, the birthright stays where it fell. The double portion belongs to whichever son was born first.

Then parents whose grown son will not obey them and will not be corrected. They bring him to the elders at the town gate and state the charge, and the men of the city carry out the sentence.

The chapter closes with a man already executed whose body has been hung up for public shame. It must be down and buried before dark, so the land God is giving Israel is not defiled.

One Word Summary

• Answerable: every law names who has to act.
• Bloodguilt: the chapter opens on blood nobody has answered for.
• Limits: every household authority here is fenced.
• Dignity: even a dismissed captive and an executed criminal are protected from contempt.

In One Sentence

Parents must bring a defiant grown son to the city elders, a soldier must marry a captive woman properly or release her, a father must give the double portion to his true firstborn, a town must answer for a murder it did not commit, and every executed body must be buried before dark, because in God’s land every life is answered for and every authority is fenced.

Theme of Deuteronomy 21

Deuteronomy 21 is about the worth of a human life and the limits God puts on the people who hold power over one. Two more ideas run alongside it: the stain an unpunished killing leaves on a whole community, and the dignity God protects even where He has already judged. Nobody in this chapter is disposable. A murdered stranger, a woman taken in war, an overlooked son, a defiant son, and a criminal already dead are each given something the people around them could have withheld.

Deuteronomy 21 Outline

• Deuteronomy 21:1-2: A body is found in open country, and the elders and judges measure from it to the surrounding towns.
• Deuteronomy 21:3-6: The elders of the nearest town break the neck of an unworked heifer in an unploughed valley and wash their hands over it before the priests.
• Deuteronomy 21:7-9: The elders declare their innocence and ask God not to charge the nation with the blood.
• Deuteronomy 21:10-14: A soldier who wants to marry a woman taken captive in war must wait a full month, and if he changes his mind he must set her free.
• Deuteronomy 21:15-17: A father may not give the birthright to a favoured wife’s son ahead of his actual firstborn.
• Deuteronomy 21:18-21: Parents bring a defiant grown son to the city elders, and the men of the city stone him.
• Deuteronomy 21:22-23: A body hung up after execution must be buried the same day.

The Elders’ Prayer

What the whole opening ceremony builds to is a short prayer the elders say out loud over the animal. It is one of the few prayers in the law of Moses whose exact words are written down for the people to use.

“And they shall answer and say, Our hands have not shed this blood, neither have our eyes seen it. Be merciful, O LORD, unto thy people Israel, whom thou hast redeemed, and lay not innocent blood unto thy people of Israel’s charge. And the blood shall be forgiven them.”

Deuteronomy 21:7-8

Our hands are clean of this blood, and the killing happened out of our sight. Cover the sin of Your people Israel, whom You bought out of Egypt, and leave this death off their account.

It has four parts:

• The denial. They swear to their own innocence in both act and knowledge. In Israel the gesture of washing the hands stood for clearing yourself of a charge (Psalm 26:6).
• The plea. They ask God to be merciful. The word behind “be merciful” is the same word used for making atonement, and it carries the picture of covering something over.
• The ground. They ask on the basis of what God has already done: “whom thou hast redeemed.” They are His by rescue before they are His by obedience.
• The request and the answer. They ask Him not to charge the nation with the death, and the law tells them plainly that it will be forgiven.

These men had no hand in the death, and they still stand there asking God to forgive a nation that has one among them.

Observations from Deuteronomy 21

The Chapter Opens and Closes on the Land God Is Giving

Verse 1 begins “in the land which the LORD thy God giveth thee to possess it.” Verse 23 ends “that thy land be not defiled, which the LORD thy God giveth thee for an inheritance.” The gift is stated first and the danger to it is stated last, and everything between the two is about keeping the gift clean. God gave Israel a place, and how they handled blood in it was going to decide what kind of place it stayed.

Three Laws in a Row Fence a Household’s Authority

The captive-woman law limits a husband (21:10-14). The birthright law limits a father (21:15-17). The rebellious-son law limits both parents together (21:18-21).

Each one leaves the authority standing and puts a wall around it. The head of a household keeps his place in these verses, and God tells him where his power stops.

The Elders Are Called In Where a Family Could Have Acted Alone

A town’s elders travel out to a corpse that is nobody’s relative (21:2-6), and parents at the end of their patience have to walk their son to those same elders at the gate (21:19-20). Both times a private matter is taken into public hands. Israel was not left to settle blood and rebellion behind closed doors, which protected the accused as much as it protected everyone else.

Two of These Laws Begin With Attraction and Preference

A soldier sees “a beautiful woman” and wants her (21:11). A husband with two wives cares more for one of them (21:15). Both laws exist because of what a man felt, and both tell him that his feelings do not decide what happens next. The chapter treats attraction and preference as real and refuses to let either one set the terms.

Difficult Verses Explained

Does Deuteronomy 21 Permit a Soldier to Force Himself on a Captive?

No, and the order of the clauses in verse 13 is the answer. Everything else comes first, and only then: “and after that thou shalt go in unto her, and be her husband, and she shall be thy wife.” Marriage comes before any relations, and a full month of mourning stands in front of the marriage.

What the law forbids is what commonly happened to captured women elsewhere in the ancient world, and what it gives her is a wife’s standing, a month in which she is untouchable, and her liberty rather than a sale price if the man changes his mind. Scripture regulates a practice that war produced; it never presents that world as good.

What Does It Mean That One Wife Was “Hated”?

It means loved less. Scripture uses “hated” in that softer sense elsewhere: “And when the LORD saw that Leah was hated, he opened her womb” (Genesis 29:31), which describes a wife whose husband preferred her sister. So verse 15 pictures an ordinary and painful household in which two wives share one husband and one of them holds his heart. This law leaves the question of that household aside and does one thing: it protects a boy from paying for where his mother stands in his father’s affections.

Did God Command Parents to Have Their Sons Stoned?

The law describes a last resort, reached after everything else has failed, and the wording is careful about who it covers. The son is old enough to be called “a glutton, and a drunkard” (21:20), meaning settled adult habits, and his parents have already corrected him and been ignored (21:18). They could not carry out any sentence themselves; they had to bring the charge to the city elders, and the men of the city acted.

Scripture records no case of this law ever being carried out, and later Jewish teachers, writing in the Mishnah, defined the charge so narrowly that a conviction became close to impossible. The chapter itself gives the purpose: “all Israel shall hear, and fear” (21:21). The word pair used of him, “stubborn and rebellious,” is the same pair Scripture later turns on the whole nation, which is called “a stubborn and rebellious generation” in Psalm 78:8.

Common Misunderstandings

• That the heifer was a sacrifice. Its neck was broken rather than its throat cut, no blood was shed or sprinkled, and it was never brought to the altar. Bible teachers widely read it as standing in for a murderer who could not be found, taking the death he should have died.
• That the man in verse 22 was executed by hanging. He was already dead. Israel executed by stoning or by the sword, and the body was afterwards hung up in public as an added mark of disgrace (compare Joshua 10:26).
• That the chapter approves of a man having two wives. It regulates the situation without commending it. God gave laws that limited the damage of things He never endorsed, and the two-wife homes Scripture shows us are homes in conflict.
• That rebellious sons were regularly stoned in Israel. The Bible records no instance of it, and Jewish tradition preserves none either. The law stood on the books as a warning.

Christ Connection

Paul settles the link between this chapter and Jesus by quoting verse 23 outright: “Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree” (Galatians 3:13). Christ bought us out from under the law’s sentence by taking that sentence on Himself, and Paul proves it from Deuteronomy 21.

The next verse says why He did it, “that the blessing of Abraham might come on the Gentiles through Jesus Christ” (Galatians 3:14). He took the verdict this chapter pronounces so that the promise made to Abraham could reach people born outside Israel. The apostles kept reaching for the same wording:

• Acts 5:30 and Acts 10:39 both say the Jesus God raised is the one “whom ye slew and hanged on a tree.”
• Acts 13:29 says that when everything written of Him was fulfilled, “they took him down from the tree, and laid him in a sepulchre.”
• 1 Peter 2:24 says He “bare our sins in his own body on the tree.”

One thing here is easy to get backwards. God’s curse came first, and the tree displayed it. Jesus went to that cross already carrying our sin, and God “hath made him to be sin for us, who knew no sin” (2 Corinthians 5:21).

God treated the sinless Son as the guilty party in our place. Notice too that verse 23 was obeyed at the cross itself. The bodies were not left hanging overnight (John 19:31), and He was taken down and buried the same day, which means the last law in this chapter was kept for Him.

Scripture does not draw this last line for us, so hold it loosely: the charge the parents bring in verse 20, “he is a glutton, and a drunkard,” is close to the accusation thrown at Jesus in the Gospels, “Behold a man gluttonous, and a winebibber” (Matthew 11:19). The chapter that condemns a defiant son and curses a hanged man is the chapter the obedient Son died under.

When, Where, and Why

• When: Late in the fortieth year after Israel left Egypt, in the eleventh month of that year (Deuteronomy 1:3), a short time before the crossing into Canaan and before Moses’ death.
• Where: The plains of Moab, east of the Jordan River and opposite Jericho (Deuteronomy 1:5). Nothing in this chapter happens there; it is all law for a country Israel has not entered yet.
• Why: Moses is preparing people who have only ever lived in a camp to live spread out in towns and fields, where a body can lie unfound and a household can do as it likes behind its own door. Every one of these five laws assumes exactly that situation. Many who study how Deuteronomy is arranged read chapters 19 to 22 as one block working out the sixth commandment, “Thou shalt not kill,” which fits a run of chapters this taken up with blood and with people at someone else’s mercy.

Key Verses

“Be merciful, O LORD, unto thy people Israel, whom thou hast redeemed, and lay not innocent blood unto thy people of Israel’s charge.”

Deuteronomy 21:8

Show mercy to the nation You redeemed, and keep this killing off its record. It is the only place in the chapter where anyone speaks to God, and the men praying are the ones the passage has just called innocent.

“But thou shalt not sell her at all for money, thou shalt not make merchandise of her, because thou hast humbled her.”

Deuteronomy 21:14

You must never sell her or treat her as goods, because you have already brought her low. This is the clause that turns a prisoner of war into a person the law will defend.

“But he shall acknowledge the son of the hated for the firstborn, by giving him a double portion of all that he hath: for he is the beginning of his strength; the right of the firstborn is his.”

Deuteronomy 21:17

The father must own his eldest boy as the firstborn and give him twice the share of every other son, because that boy is the first proof of his father’s strength and the birthright already belongs to him. A right that exists before a preference does is not cancelled by the preference.

“His body shall not remain all night upon the tree, but thou shalt in any wise bury him that day; (for he that is hanged is accursed of God;) that thy land be not defiled, which the LORD thy God giveth thee for an inheritance.”

Deuteronomy 21:23

The body must be buried the same day and never left hanging overnight, because a man displayed that way is under God’s curse and would defile the land God is giving them. It is the one line of Deuteronomy 21 most readers arrive already carrying, and the reason this chapter matters far outside Israel.

Key Lessons from Deuteronomy 21

• Guilt that has no owner still has to be dealt with, which is why a town nobody accused had to act over a body nobody claimed (21:1-9).
• A community shares responsibility for what happens within its reach, and Israel could not shrug at a death outside its walls (21:2-8).
• God grants real authority to a husband, a father and parents, and He puts a boundary around each one (21:10-21).
• A father’s estate follows the order his sons were born in rather than the order he loves their mothers in (21:15-17).
• Even where God has judged, He protects the person from contempt, and the body of a condemned man had to be buried before dark (21:22-23).

Bible Study Questions

1. Read Deuteronomy 21:1-9. What does the town have to do, and what does the passage never ask it to do?
2. In verse 8 the elders pray for a nation over a sin none of them committed. Where should Christians be praying that way now?
3. Verses 10 to 21 place a limit on three kinds of household authority in turn. What does each one still get to decide, and what is taken out of its hands?
4. Verse 13 puts a full month between a soldier’s desire and his marriage. What is that month doing for her, and what is it doing to him?
5. Verse 22 describes a man who is already dead before anything in the law applies to him. Why does that change how you read Galatians 3:13?
6. Verse 23 says the land itself would be defiled. What does the chapter seem to assume about the connection between a people and the place they live in?

1 If one be found slain in the land which the LORD thy God giveth thee to possess it, lying in the field, and it be not known who hath slain him:

2 Then thy elders and thy judges shall come forth, and they shall measure unto the cities which are round about him that is slain:

3 And it shall be, that the city which is next unto the slain man, even the elders of that city shall take an heifer, which hath not been wrought with, and which hath not drawn in the yoke;

4 And the elders of that city shall bring down the heifer unto a rough valley, which is neither eared nor sown, and shall strike off the heifer’s neck there in the valley:

5 And the priests the sons of Levi shall come near; for them the LORD thy God hath chosen to minister unto him, and to bless in the name of the LORD; and by their word shall every controversy and every stroke be tried:

6 And all the elders of that city, that are next unto the slain man, shall wash their hands over the heifer that is beheaded in the valley:

7 And they shall answer and say, Our hands have not shed this blood, neither have our eyes seen it.

8 Be merciful, O LORD, unto thy people Israel, whom thou hast redeemed, and lay not innocent blood unto thy people of Israel’s charge. And the blood shall be forgiven them.

9 So shalt thou put away the guilt of innocent blood from among you, when thou shalt do that which is right in the sight of the LORD.

10 When thou goest forth to war against thine enemies, and the LORD thy God hath delivered them into thine hands, and thou hast taken them captive,

11 And seest among the captives a beautiful woman, and hast a desire unto her, that thou wouldest have her to thy wife;

12 Then thou shalt bring her home to thine house; and she shall shave her head, and pare her nails;

13 And she shall put the raiment of her captivity from off her, and shall remain in thine house, and bewail her father and her mother a full month: and after that thou shalt go in unto her, and be her husband, and she shall be thy wife.

14 And it shall be, if thou have no delight in her, then thou shalt let her go whither she will; but thou shalt not sell her at all for money, thou shalt not make merchandise of her, because thou hast humbled her.

15 If a man have two wives, one beloved, and another hated, and they have born him children, both the beloved and the hated; and if the firstborn son be hers that was hated:

16 Then it shall be, when he maketh his sons to inherit that which he hath, that he may not make the son of the beloved firstborn before the son of the hated, which is indeed the firstborn:

17 But he shall acknowledge the son of the hated for the firstborn, by giving him a double portion of all that he hath: for he is the beginning of his strength; the right of the firstborn is his.

18 If a man have a stubborn and rebellious son, which will not obey the voice of his father, or the voice of his mother, and that, when they have chastened him, will not hearken unto them:

19 Then shall his father and his mother lay hold on him, and bring him out unto the elders of his city, and unto the gate of his place;

20 And they shall say unto the elders of his city, This our son is stubborn and rebellious, he will not obey our voice; he is a glutton, and a drunkard.

21 And all the men of his city shall stone him with stones, that he die: so shalt thou put evil away from among you; and all Israel shall hear, and fear.

22 And if a man have committed a sin worthy of death, and he be to be put to death, and thou hang him on a tree:

23 His body shall not remain all night upon the tree, but thou shalt in any wise bury him that day; (for he that is hanged is accursed of God;) that thy land be not defiled, which the LORD thy God giveth thee for an inheritance.
