Genesis 15:12-16 American Standard Version (ASV)

12. And when the sun was going down, a deep sleep fell upon Abram; and, lo, a horror of great darkness fell upon him.

13. And he said unto Abram, Know of a surety that thy seed shall be sojourners 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. But thou shalt go to thy fathers in peace; thou shalt be buried in a good old age.

16. And in the fourth generation they shall come hither again; for the iniquity of the Amorite is not yet full.
