“And he believed in the LORD; and he counted it to him for righteousness.” That one line, dropped into the middle of a chapter about a childless man and a covenant, is the sentence Paul later uses to explain how anyone is made right with God. This Genesis 15 summary takes the whole chapter that verse sits in, from the first promise to the covenant God signs alone.

Setting the Stage
God had told a man named Abram to leave his country for a land He would show him, and He promised to make him a great nation (Genesis 12:1-3). Abram went. Years passed in Canaan and no child was born, so a promise about a nation had nobody to land on.
Then Abram armed his household, chased down four kings who had carried off his nephew Lot, and won. On the way home the king of Sodom offered him everything he had recovered, and Abram turned all of it down. That is the man God speaks to when Genesis 15 opens. For the whole book in one place, see our Book of Genesis summary by chapter.
Concise Genesis 15 Summary
One Word Summary
- Covenant: God binds Himself to Abram by a ceremony only He walks through.
- Believed: the chapter’s own verb, and its hinge at verse 6.
- Assurance: two honest questions, two answers, no rebuke.
In One Sentence
God promises childless Abram a son and descendants beyond counting, Abram believes Him and is counted righteous, and God then seals the promise of the land by passing alone between the pieces of Abram’s sacrifice.
Theme of Genesis 15
Genesis 15 is about a promise that rests entirely on God. A childless man is given an heir, a nation and a country, and he supplies none of the three. Three connected ideas run alongside that main one.
Belief itself was credited as righteousness. God met honest questions with answers rather than with correction. And God spoke about four centuries He had not yet brought about as calmly as if they were already behind Him.
Genesis 15 Outline
- Genesis 15:1: God comes to Abram after the battle and promises to be his shield and his reward.
- Genesis 15:2-6: Abram says he has no son, God promises descendants like the stars, and Abram believes.
- Genesis 15:7-11: Abram asks how he can be sure of the land, and God tells him to prepare a covenant sacrifice.
- Genesis 15:12-16: In a deep sleep and a great darkness, God tells Abram what will happen to his descendants.
- Genesis 15:17-21: God passes between the pieces alone and names the land He is giving.
Comprehensive Genesis 15 Summary
Abram has just made powerful enemies and walked away from a fortune, so God offers Himself as the answer to both: “Fear not, Abram: I am thy shield, and thy exceeding great reward” (Genesis 15:1). Abram’s reply says that neither the shield nor the reward reaches his real trouble.
He has no son, and by the custom of his day a trusted household servant like Eliezer would have inherited what he owned. A shield guards what a man has, and a reward adds to it, and Abram has nobody to leave any of it to.
God answers by ruling Eliezer out and taking Abram outside to look up. The descendants will come from Abram’s own body, and they will be past counting, like the stars. Abram believes Him, and God credits that belief to him as righteousness. Nothing in his tent has changed; the one difference is that he now takes God at His word.
The chapter then turns from the son to the land, and Abram asks a second question: how can he know he will inherit it? God does not repeat the promise louder. He sends Abram for five creatures instead.
Abram knows what that means without being told, because it is how agreements were sealed in his day. He cuts them, lays the halves opposite each other, and waits, driving off the birds that come down on them.
The waiting ends at sunset in a deep sleep and a heavy darkness, and God speaks into it. What He says is not comfort. Four centuries of slavery in a foreign country stand between this promise and the land, and Abram will die peacefully long before any of it.
Then, in the dark, a smoking furnace and a burning lamp move between the pieces, and the covenant is made while Abram sleeps. The very next chapter shows him and Sarai trying to produce the promised son themselves.

The Covenant of the Pieces
“And it came to pass, that, when the sun went down, and it was dark, behold a smoking furnace, and a burning lamp that passed between those pieces.”
Genesis 15:17
In Abram’s world, two parties sealed an agreement by cutting animals in half, laying the halves in two rows, and walking together between them. The message of the walk was plain: let this be done to me if I break my word.
The Bible records the same practice centuries later, when Judah’s leaders “cut the calf in twain, and passed between the parts” (Jeremiah 34:18-19), and the same ceremony turns up in treaty texts recovered from the ancient Near East. The Hebrew phrase behind “made a covenant” in verse 18 is literally to cut a covenant.

|---|---|
| Parties | The LORD and Abram (Genesis 15:18) |

| Attached prophecy | Four hundred years of affliction, judgment on the oppressing nation, an exodus with great wealth, Abram’s own peaceful death, and a return in the fourth generation (vv. 13-16) |
| Significance | Both sides should have walked. One did, and the covenant stands or falls on Him. |

Observations from Genesis 15
God answers both of Abram’s questions and rebukes neither
Abram asks twice. “What wilt thou give me, seeing I go childless” (v. 2), and “whereby shall I know that I shall inherit it” (v. 8). The second one comes after God has already counted him righteous, which means a man can be right with God and still want something to hold on to.
God gives him stars for the first question and a covenant for the second. Neither time is Abram told to stop asking, which fits a chapter where nothing ever rested on Abram getting it right.
Abram is told he will die before any of it happens
In the middle of a promise about descendants and land, God says, “thou shalt go to thy fathers in peace; thou shalt be buried in a good old age” (v. 15). Abram would be dead for centuries before the nation, the exodus or the land arrived. He believes it anyway.
Hebrews 11:13 later describes exactly this: “These all died in faith, not having received the promises, but having seen them afar off.” That is what makes the belief of verse 6 cost something: Abram is trusting God with a future he will not be alive to see.
The birds are driven off and the chapter says nothing more
“And when the fowls came down upon the carcases, Abram drove them away” (v. 11). That is the whole verse. Bible teachers have suggested the birds picture enemies, or doubt, or Israel’s later troubles, but Genesis 15 assigns them no meaning at all.
It shows Abram guarding what God told him to prepare, through hours of nothing happening, until God finally comes. Reading the verse for what it says, and no further, keeps the chapter honest.
The delay belongs to the Amorites, not to Israel
God gives a reason for the four hundred years: “the iniquity of the Amorites is not yet full” (v. 16). Israel is waiting on somebody else’s account. The people already living in Canaan are being given time.
Peter says the same thing about God’s patience in his own day, that He is “longsuffering to us-ward, not willing that any should perish” (2 Peter 3:9). The chapter that promises the land also shows God holding it back so that the people under sentence get four more centuries.
Difficult Verses Explained
The four hundred years (Genesis 15:13)
Genesis 15:13 says four hundred years, Exodus 12:40 says the sojourning of the children of Israel, who dwelt in Egypt, was four hundred and thirty years, and Galatians 3:17 counts four hundred and thirty years to the giving of the law. Bible teachers hold three readings. Some take four hundred as a round number for four hundred and thirty.
Some take the sojourn as four hundred and thirty years with the affliction being the last four hundred of them, the first thirty being the years of favour under Joseph’s Pharaoh. Others read Galatians 3:17 as counting from Abram’s entry into Canaan, which leaves roughly two hundred and fifteen years in Egypt. Each reading keeps the text intact, and the chapter itself does not settle between them.
“The fourth generation” (Genesis 15:16)
This may mean four literal generations, and the line of Levi, Kohath, Amram and Moses fits that reading. It may instead mean four lifetimes, since a lifetime in the patriarchal narratives can run well past a hundred years. Both are held by careful readers.
The smoking furnace and the burning lamp (Genesis 15:17)
Genesis 15 does not say what they stand for. Both images are used elsewhere of God being present with His people, in the pillar of cloud and fire that led Israel out of Egypt (Exodus 13:21-22) and in the smoke on Sinai (Exodus 19:18), and that is the strongest ground for reading them as God Himself passing through.
Some teachers go further and read the furnace as Egypt’s affliction and the lamp as the deliverance out of it. That is an old and attractive reading, but the chapter does not state it, so it is better held loosely than preached as fact.
Christ Connection
The lone walk of verse 17 is where this chapter reaches Christ most directly. By going through alone, God took both halves of the obligation and both halves of the penalty for breaking it. Centuries later Paul writes that “Christ hath redeemed us from the curse of the law, being made a curse for us” (Galatians 3:13), and that the record standing against us was nailed to His cross (Colossians 2:14).
Read alongside those verses, the lone walk points toward a cross where God carried the penalty owed by the side that could not keep the covenant, and that side is ours. Hebrews explains why God bound Himself this way at all: having no greater to swear by, He sware by Himself, so that believers “might have a strong consolation” (Hebrews 6:13-18).
Genesis 15:6 is the other road from this chapter to the gospel, and the road was already being travelled inside the Old Testament: Habakkuk 2:4 says “the just shall live by his faith.” The New Testament then takes the verse four times, each time for a different reason:
- Romans 4:3 uses it to show Abraham was counted righteous before he had done anything to earn it.
- Romans 4:9-11 points out that it happened before he was circumcised, so no ritual produced it.
- Galatians 3:6-9 concludes that people of faith, from any nation, are Abraham’s children.
- James 2:23 adds that the faith God credited was the kind that later showed itself in obedience.
Paul then says the sentence was not written for Abraham’s sake alone, “but for us also, to whom it shall be imputed, if we believe on him that raised up Jesus our Lord from the dead” (Romans 4:23-24). Even the promise of descendants runs to Christ: Galatians 3:16 reads the singular “thy seed” of Genesis 15:18 as pointing to Him.
When, Where, and Why
- When: The patriarchal period, roughly two thousand years before Christ, with the dating approximate. Within Abram’s own life the chapter falls between his leaving Haran at seventy-five (Genesis 12:4) and the birth of Ishmael when he was eighty-six (Genesis 16:16).
- Where: Canaan, the land God had already told Abram He would give him. The nearest Israel came to holding the borders of verse 18 was in Solomon’s reign, when he ruled from the river to the border of Egypt (1 Kings 4:21). Two other places are named without Abram going near them: Ur of the Chaldees, which God brought him out of (v. 7), and the unnamed foreign country of verse 13, which the rest of Scripture identifies as Egypt.
- Why: Moses is writing for people about to enter this land. He records the covenant that gives Israel its claim to it, and he records who guaranteed that covenant, so that a nation walking into Canaan would know the promise never rested on them.
Key Verses
“And he believed in the LORD; and he counted it to him for righteousness.”
Genesis 15:6
Before this verse, Genesis never says of anyone that he believed God, and it is the verse the New Testament returns to whenever it explains how a person is made right with Him. Note what it does not say. It does not say Abram believed in God, which even devils do (James 2:19). It says he believed God, and took Him at His word.
“But in the fourth generation they shall come hither again: for the iniquity of the Amorites is not yet full.”
Genesis 15:16
God explains a four-century delay by pointing to people outside Israel and how much time they still had. Judgment in Genesis is not hasty, and this verse is one of the clearest places the book says so.
“And it came to pass, that, when the sun went down, and it was dark, behold a smoking furnace, and a burning lamp that passed between those pieces.”
Genesis 15:17
Abram had asked for something he could be sure of, and then slept through the giving of it. The sign came late, after a day of waiting and after the darkness had fallen, and it was finished without him.
Key Lessons from Genesis 15
- God met a fearful man by offering Himself as both protection and payment rather than by explaining away the fear (v. 1).
- God let Abram ask for proof and then gave it, instead of treating the request as unbelief (v. 8).
- Faith is taking God at His word before anything visible has changed, and that is what God counted as righteousness (v. 6).
- A promise you may not live to see is still worth believing, because it rests on someone who outlives you (v. 15).

Bible Study Questions
- In Genesis 15:1, God calls Himself Abram’s shield and his exceeding great reward. Read Genesis 14:21-24 first. Why do those two words answer what Abram had just done?
- Abram asks God two questions, in verse 2 and in verse 8. How does God answer each one, and what does the difference between the two answers tell you?
- Verse 6 says God counted Abram’s belief to him for righteousness. What had Abram done at that point, and what had he not done?
- Read verses 9 to 11 and then verse 17. Who was supposed to pass between the pieces, and who actually did?
- God tells Abram in verse 15 that he will die before any of the promise arrives. What would it take for you to keep believing something you will not live to see?
- Verse 16 explains the four hundred year delay by the guilt of the Amorites. How does that change the way you read God’s patience with people who are not yet under judgment?
Genesis 15 Paraphrased
After the battle, God spoke to Abram in a vision. He said, do not be afraid. I am your shield. I am your great reward.
Abram said, what good is any gift to me? I have no son. When I die, my servant Eliezer will get everything I own.
God said no. Your own son will be your heir. Then God took Abram outside. He said, look up and count the stars if you can.
That is how many people will come from you. Abram believed God. And God counted that belief as being right with Him.
God said, I am the one who brought you out of Ur. I brought you here to give you this land. Abram said, how can I be sure?
God told him to bring five animals. He brought a young cow, a goat, a ram, a dove and a pigeon.
Abram cut the animals in two. He laid the halves in two rows facing each other.
He did not cut the birds. Birds came down to eat the meat. Abram chased them away.
The sun began to set. A deep sleep came over Abram. A heavy darkness and a terror fell on him.
God said, know this for sure. Your family will live in a foreign country. They will be slaves there.
They will suffer for four hundred years. But I will punish that nation.
Your family will come out of it with great wealth. You yourself will die in peace. You will be old, and you will be buried.
God said, four generations later they will come back here. The people living in this land are not ready for judgment yet. Then the sun went down and it was dark. Abram saw a smoking oven and a burning torch.
They moved between the rows of meat. That day the Lord made an agreement with Abram. He said, I have given this land to your children.
It runs from the river of Egypt to the great river Euphrates. Then He named the ten peoples living there.
Frequently Asked Questions
Why did God make Abram look at the stars?
The stars gave Abram a picture of the promise he could go outside and check. God had already compared his descendants to the dust of the earth (Genesis 13:16), which a man can see anywhere at any time. The stars added a second picture, on a scale nobody counts, and it arrived on the night Abram had just said he had no child at all.
Why did God tell Abram to cut the animals in half?
Because that was how a binding agreement was made in Abram’s day. The two parties walked between the halves, accepting the animals’ fate on themselves if they broke their word. Jeremiah 34:18-19 describes the same practice. What makes Genesis 15 different is that only God walked through.
Who was Eliezer of Damascus?
Eliezer was the trusted servant who ran Abram’s household (Genesis 15:2). Under the custom of that time, a childless man could make such a servant his heir, and that servant would be displaced if a natural son was later born. Abram names him because, as things stood, Eliezer was going to inherit everything.
How old was Abram in Genesis 15?
The chapter does not give his age. It falls between two ages Genesis does give: he was seventy-five when he left Haran (Genesis 12:4), and eighty-six when Ishmael was born (Genesis 16:16). So he was somewhere in his late seventies or early eighties, and had already been waiting years for the promised son.
Is the Abrahamic covenant conditional or unconditional?
Genesis 15 presents it as one-sided. In a two-sided agreement both parties walked between the pieces and both carried the penalty for breaking it. Here God passed through alone while Abram slept, which places the whole obligation on God. God later gave circumcision as the sign of this covenant (Genesis 17:9-14), but the ceremony of Genesis 15 rests on Him.
Genesis 15, The Full Text (KJV)
Read the full chapter below for reference.
1 After these things the word of the LORD came unto Abram in a vision, saying, Fear not, Abram: I am thy shield, and thy exceeding great reward.
2 And Abram said, Lord GOD, what wilt thou give me, seeing I go childless, and the steward of my house is this Eliezer of Damascus?
3 And Abram said, Behold, to me thou hast given no seed: and, lo, one born in my house is mine heir.
4 And, behold, the word of the LORD came unto him, saying, This shall not be thine heir; but he that shall come forth out of thine own bowels shall be thine heir.
5 And he brought him forth abroad, and said, Look now toward heaven, and tell the stars, if thou be able to number them: and he said unto him, So shall thy seed be.
6 And he believed in the LORD; and he counted it to him for righteousness.
7 And he said unto him, I am the LORD that brought thee out of Ur of the Chaldees, to give thee this land to inherit it.
8 And he said, Lord GOD, whereby shall I know that I shall inherit it?
9 And he said unto him, Take me an heifer of three years old, and a she goat of three years old, and a ram of three years old, and a turtledove, and a young pigeon.
10 And he took unto him all these, and divided them in the midst, and laid each piece one against another: but the birds divided he not.
11 And when the fowls came down upon the carcases, Abram drove them away.
12 And when the sun was going down, a deep sleep fell upon Abram; and, lo, an horror of great darkness fell upon him.
13 And he said unto Abram, Know of a surety that thy seed shall be a stranger in a land that is not theirs, and shall serve them; and they shall afflict them four hundred years;
14 And also that nation, whom they shall serve, will I judge: and afterward shall they come out with great substance.
15 And thou shalt go to thy fathers in peace; thou shalt be buried in a good old age.
16 But in the fourth generation they shall come hither again: for the iniquity of the Amorites is not yet full.
17 And it came to pass, that, when the sun went down, and it was dark, behold a smoking furnace, and a burning lamp that passed between those pieces.
18 In the same day the LORD made a covenant with Abram, saying, Unto thy seed have I given this land, from the river of Egypt unto the great river, the river Euphrates:
19 The Kenites, and the Kenizzites, and the Kadmonites,
20 And the Hittites, and the Perizzites, and the Rephaims,
21 And the Amorites, and the Canaanites, and the Girgashites, and the Jebusites.
