5 so your name won’t be Abram any longer. Instead, your name will be Abraham17:5. The name change is usually interpreted to be from Abram ("exalted father") to Abraham ("father of many"). because I’m going to make you the father of many nations.
10 This is my agreement with you and your descendants who come after you, the agreement you are to keep: every male among you shall be circumcised.
16 I will bless her and I promise to give you a son by her. I will bless her so that she will become the mother of nations, and kings will be among her descendants."
17 Abraham bowed down with his face to the ground. But inside he was laughing, asking himself, "How on earth could I have a son at the age of one hundred? How could Sarah have a child when she is ninety?"
19 "No, it’s your wife Sarah who is going to have a son for you!" God replied. "You are to call him Isaac.17:19. Isaac means "he laughs." I will keep my agreement with him and his descendants as an eternal agreement.
23 That day Abraham circumcised his son Ishmael as well as all those born in his household or purchased, in fact every male among the members of Abraham’s household, just as God had told him.
