Acts 7:6-8

Revised Standard Version

⁶ And God spoke to this effect, that his posterity would be aliens in a land belonging to others, who would enslave them and ill-treat them four hundred years. ⁷ ‘But I will judge the nation which they serve,’ said God, ‘and after that they shall come out and worship me in this place.’ ⁸ And he gave him the covenant of circumcision. And so Abraham became the father of Isaac, and circumcised him on the eighth day; and Isaac became the father of Jacob, and Jacob of the twelve patriarchs.
