Genesis 15:14-16

Young's Literal Translation

¹⁴ and the nation also whom they serve I judge, and after this they go out with great substance;

¹⁵ and thou -- thou comest in unto thy fathers in peace; thou art buried in a good old age;

¹⁶ and the fourth generation doth turn back hither, for the iniquity of the Amorite is not yet complete.'
