Acts 7:5-8

⁵And He gave him no inheritance in it, not even a place to put his foot on, and He promised to give it to him for a possession, and to his descendants after him, though he had no child.

⁶But God spoke in this way: that his offspring would dwell in a foreign land, and that they would enslave them, and they would treat them badly four hundred years.

⁷‘And the nation which they will serve, I will judge,’ said God, ‘and after these things they will come out and serve Me in this place.’

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