Genesis 15:8–16

But he said, “O Lord God, how am I to know that I shall possess it?” He said to him, “Bring me a heifer three years old, a female goat three years old, a ram three years old, a turtledove, and a young pigeon.” And he brought him all these, cut them in half, and laid each half over against the other. But he did not cut the birds in half. And when birds of prey came down on the carcasses, Abram drove them away.

As the sun was going down, a deep sleep fell on Abram. And behold, dreadful and great darkness fell upon him. Then the Lord said to Abram, “Know for certain that your offspring will be sojourners in a land that is not theirs and will be servants there, and they will be afflicted for four hundred years. But I will bring judgment on the nation that they serve, and afterward they shall come out with great possessions. As for you, you shall go to your fathers in peace; you shall be buried in a good old age. And they shall come back here in the fourth generation, for the iniquity of the Amorites is not yet complete.”

But Abram said, “Sovereign Lord, how can I know that I will gain possession of it?”

So the Lord said to him, “Bring me a heifer, a goat and a ram, each three years old, along with a dove and a young pigeon.”

Abram brought all these to him, cut them in two and arranged the halves opposite each other; the birds, however, he did not cut in half. Then birds of prey came down on the carcasses, but Abram drove them away.

As the sun was setting, Abram fell into a deep sleep, and a thick and dreadful darkness came over him. Then the Lord said to him, “Know for certain that for four hundred years your descendants will be strangers in a country not their own and that they will be enslaved and mistreated there. But I will punish the nation they serve as slaves, and afterward they will come out with great possessions. You, however, will go to your ancestors in peace and be buried at a good old age. In the fourth generation your descendants will come back here, for the sin of the Amorites has not yet reached its full measure.”

But he said, “Lord God, how can I know that I will possess it?”

He said to him, “Bring me a three-year-old cow, a three-year-old female goat, a three-year-old ram, a turtledove, and a young pigeon.”

So he brought all these to him, cut them in half, and laid the pieces opposite each other, but he did not cut the birds in half. Birds of prey came down on the carcasses, but Abram drove them away. As the sun was setting, a deep sleep came over Abram, and suddenly great terror and darkness descended on him.

Then the Lord said to Abram, “Know this for certain: Your offspring will be resident aliens for four hundred years in a land that does not belong to them and will be enslaved and oppressed. However, I will judge the nation they serve, and afterward they will go out with many possessions. But you will go to your ancestors in peace and be buried at a good old age. In the fourth generation they will return here, for the iniquity of the Amorites has not yet reached its full measure.”

But Abram replied, “O Sovereign Lord, how can I be sure that I will actually possess it?”

The Lord told him, “Bring me a three-year-old heifer, a three-year-old female goat, a three-year-old ram, a turtledove, and a young pigeon.” So Abram presented all these to him and killed them. Then he cut each animal down the middle and laid the halves side by side; he did not, however, cut the birds in half. Some vultures swooped down to eat the carcasses, but Abram chased them away.

As the sun was going down, Abram fell into a deep sleep, and a terrifying darkness came down over him. Then the Lord said to Abram, “You can be sure that your descendants will be strangers in a foreign land, where they will be oppressed as slaves for 400 years. But I will punish the nation that enslaves them, and in the end they will come away with great wealth. (As for you, you will die in peace and be buried at a ripe old age.) After four generations your descendants will return here to this land, for the sins of the Amorites do not yet warrant their destruction.”

And he said, “O Yahweh God, how shall I know that I will possess it?” And he said to him, “Take for me a three-year-old heifer, and a three-year-old female goat, and a three-year-old ram, and a turtledove and a young pigeon.” And he took for him all these and cut them in pieces down the middle. And he put each piece opposite the other, but the birds he did not cut. And the birds of prey came down on the carcasses, but Abram drove them away. And it happened, as the sun went down, then a deep sleep fell upon Abram and, behold, a great terrifying darkness fell upon him. And he said to Abram, “You must surely know that your descendants shall be as aliens in a land not their own. And they shall serve them and they shall oppress them four hundred years. And also the nation that they serve I will judge. Then afterward they shall go out with great possessions. And as for you, you shall go to your ancestors in peace; you shall be buried in a good old age. And the fourth generation shall return here, for the guilt of the Amorites is not yet complete.”

And he said, Lord God, whereby shall I know that I shall inherit it? 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. 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. And when the fowls came down upon the carcases, Abram drove them away. And when the sun was going down, a deep sleep fell upon Abram; and, lo, an horror of great darkness fell upon him. 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; And also that nation, whom they shall serve, will I judge: and afterward shall they come out with great substance. And thou shalt go to thy fathers in peace; thou shalt be buried in a good old age. But in the fourth generation they shall come hither again: for the iniquity of the Amorites is not yet full.
