Acts 7:2-8

2And he said, “Brethren and fathers, listen: The God of glory appeared to our father Abraham when he was in Mesopotamia, before he dwelt in Haran,

3and said to him, ‘Get out of your country and from your relatives, and come to a land that I will show you.’

4Then he came out of the land of the Chaldeans and dwelt in Haran. And from there, when his father was dead, He moved him to this land in which you now dwell.

5And God gave him no inheritance in it, not even enough to set his foot on. But even when Abraham had no child, He promised to give it to him for a possession, and to his descendants after him.

6But God spoke in this way: that his descendants would dwell in a foreign land, and that they would bring them into bondage and oppress them four hundred years.

7‘And the nation to whom they will be in bondage I will judge,’ said God, ‘and after that they shall come out and serve Me in this place.’

8Then He gave him the covenant of circumcision; and so Abraham begot Isaac and circumcised him on the eighth day; and Isaac begot Jacob, and Jacob begot the twelve patriarchs.
