Genesis 15:13-16

New International Version - UK

¹³ Then 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 ill-treated there. ¹⁴ But I will punish the nation they serve as slaves, and afterwards they will come out with great possessions. ¹⁵ You, however, will go to your ancestors in peace and be buried at a good old age. ¹⁶ In the fourth generation your descendants will come back here, for the sin of the Amorites has not yet reached its full measure.’
