Genesis 15:9-17

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.
