Genesis 15:7-17

7And He said to him, “I am the Lord who brought you out of 1Ur of the Chaldeans, to 2give you this land to 3possess it.” 8He said, “O Lord 4God, 5how may I know that I will 6possess it?” 9So He said to him, “7Bring 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.” 10Then he 8brought all these to Him and 9cut them 10in two, and laid each half opposite the other; but he 11did not cut the birds. 11The birds of prey came down upon the carcasses, and Abram drove them away.

12Now when the sun was going down, 12a deep sleep fell upon Abram; and behold, 13terror and great darkness fell upon him. 13God said to Abram, “Know for certain that 14your 15descendants will be strangers in a land that is not theirs, 16where 17they will be enslaved and oppressed 18four hundred years. 14But I will also judge the nation whom they will serve, and afterward they will come out 19with 20many possessions. 15As for you, 21you shall go to your fathers in peace; you will be buried at a good old age. 16Then in 22the fourth generation they will return here, for 23the iniquity of the Amorite is not yet complete.”

17It came about when the sun had set, that it was very dark, and behold, there appeared a smoking oven and a flaming torch which 24passed between these pieces.
