12As the sun was setting, Abram fell into a deep sleep, and a thick and dreadful darkness came over him. 13Then the LORD said to him, “Know for certain that for four hundred years your descendants will be strangers in a country not their own and that they will be enslaved and mistreated there. 14But I will punish the nation they serve as slaves, and afterward they will come out with great possessions. 15You, however, will go to your ancestors in peace and be buried at a good old age.
16In the fourth generation your descendants will come back here, for the sin of the Amorites has not yet reached its full measure.”
