And I will prepare an agreement between you and me. This agreement will also be for all your descendants. This agreement will continue forever. I will be your God and the God of all your descendants.
And I will give this land to you and to all your descendants. I will give you the land you are traveling through—the land of Canaan. I will give you this land forever, and I will be your God."
When the baby boy is eight days old, you will circumcise him. Every boy born among your people and every boy who is a slave of your people must be circumcised.
Abraham, this is the agreement between you and me: Any male who is not circumcised will be cut off from his people because he has broken my agreement."
Abraham bowed his face to the ground to show he respected God. But he laughed and said to himself, "I am 100 years old. I cannot have a son, and Sarah is 90 years old. She cannot have a child."
God said, "No, I said that your wife Sarah will have a son. You will name him Isaac. I will make my agreement with him that will continue forever with all his descendants.
"You mentioned Ishmael, and I heard you. I will bless him, and he will have many children. He will be the father of twelve great leaders. His family will become a great nation.
Then Abraham gathered together Ishmael and all the slaves born in his house. He also gathered all the slaves he had bought. Every man and boy in Abraham's house was gathered together, and they were all circumcised. Abraham circumcised them that day, just as God had told him to do.
