10. This is how you are to be faithful to my promise: Every male among you is to be circumcised.
11. All of you must be circumcised. That will be the sign of the promise from me to you.
12. For generations to come every male child who is eight days old must be circumcised, whether he is born in your household or bought with money from a foreigner who’s not related to you.
13. Every male born in your household or bought with your money is to be circumcised without exception. So my promise will be a sign on your flesh, an everlasting promise.
14. Any uncircumcised male must be excluded from his people because he has rejected my promise.”

17. Immediately, Abraham bowed with his face touching the ground. He laughed as he thought to himself, “Can a son be born to a hundred-year-old man? Can Sarah, a ninety-year-old woman, have a child?”
18. Then Abraham said to God, “Why not let Ishmael be my heir?”
