8. You live in the land of Canaan now as a stranger. But I will give you and your descendants all this land forever. And I will be the God of your descendants.”
9. Then God said to Abraham, “You and your descendants must keep this agreement from now on.
10. This is my agreement with you and all your descendants: Every male among you must be circumcised. You must obey this agreement.
11. Cut away the foreskin to show that you follow the agreement between me and you.
12. From now on when a baby boy is eight days old, you will circumcise him. This includes any boy born among your people or any who is your slave. (He would not be one of your descendants.)
13. So circumcise every baby boy. Circumcise him whether he is born in your family or bought as a slave. Your bodies will be marked. This will show that you are part of my agreement that lasts forever.
14. Any male who is not circumcised will be separated from his people. He has broken my agreement.”
15. God said to Abraham, “I will change the name of Sarai, your wife. Her new name will be Sarah.
16. I will bless her. I will give her a son, and you will be the father. She will be the mother of many nations. Kings of nations will come from her.”
17. Abraham bowed facedown on the ground and laughed. He said to himself, “Can a man have a child when he is 100 years old? Can Sarah give birth to a child when she is 90?”
18. Then Abraham said to God, “Please let Ishmael be the son you promised.”
