Genesis 15:7-17

7The LORD also told him, “I am the LORD, who brought you out of Ur of the Chaldeans to give you this land to possess.”

8But Abram replied, “Lord GOD, how can I know that I will possess it?”

9And the LORD said to him, “Bring Me a heifer, a goat, and a ram, each three years old, along with a turtledove and a young pigeon.”

10So Abram brought all these to Him, split each of them down the middle, and laid the halves opposite each other. The birds, however, he did not cut in half. 11And the birds of prey descended on the carcasses, but Abram drove them away. 12As the sun was setting, Abram fell into a deep sleep, and suddenly great terror and darkness overwhelmed him.

13Then the LORD said to Abram, “Know for certain that your descendants will be strangers in a land that is not their own, and they will be enslaved and mistreated four hundred years. 14But I will judge the nation they serve as slaves, and afterward they will depart with many possessions.1 15You, however, will go to your fathers in peace and be buried at a ripe old age. 16In the fourth generation your descendants will return here, for the iniquity of the Amorites is not yet complete.”

17When the sun had set and darkness had fallen, behold, a smoking firepot and a flaming torch appeared and passed between the halves of the carcasses.
