Acts 7:5-8

⁵and he gave him no inheritance in it, no, not so much as to set his foot on; and he promised to give it to him for a possession, and to his posterity after him, when as yet he had no child.

⁶And God spoke in this manner: “That his posterity should sojourn in a foreign land, and that they would bring them into bondage, and ill-treat them four hundred years;

⁷and the nation to which they shall be in bondage will I judge,” said God; “and after that they shall come forth, and shall worship me in this place.”

⁸And he gave him the covenant of circumcision; and so he begat Isaac, and circumcised him on the eighth day; and Isaac begat Jacob, and Jacob the twelve patriarchs.
