Genesis 15:12-16 - WEB
12
When the sun was going down, a deep sleep fell on Abram. Now terror and great darkness fell on him.
13
He said to Abram, "Know for sure that your seed will be sojourners in a land that is not theirs, and will serve them. They will afflict them four hundred years.
14
I will also judge that nation, whom they will serve. Afterward they will come out with great substance.
15
But you will go to your fathers in peace. You will be buried in a good old age.
16
In the fourth generation they will come here again, for the iniquity of the Amorite is not yet full."
