Acts 7:3-8

3and He said to him, ‘Leave your country and your relatives, and come to the land that I will show you.’

4Then he left the land of the Chaldeans and settled in Haran. And from there, after his father died, God sent him to this country in which you now live.

5But He did not give him inheritable property, not even enough ground to take a step on, yet He promised that He would give it to Him as a possession, and to his descendants after him.

6And this is, in effect, what God spoke [to him]: That his descendants would be aliens (strangers) in a foreign land, and that they would be enslaved and mistreated for four hundred years.

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

8And God gave Abraham a covenant [a formal agreement to be strictly observed] of [which] circumcision [was the sign]; and so [under these circumstances] Abraham became the father of Isaac, and circumcised him on the eighth day; and Isaac [became the father] of Jacob, and Jacob [became the father] of the twelve patriarchs.
