14 Any uncircumcised male must be excluded from his people because he has rejected my promise.”
15 God said to Abraham, “Don’t call your wife by the name Sarai anymore. Instead, her name is Sarah [Princess].
16 I will bless her, and I will also give you a son by her. I will bless her, and she will become ⌊a mother of⌋ nations, and kings will come from her.”
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?”
19 God replied, “No! Your wife Sarah will give you a son, and you will name him Isaac [He Laughs]. I will make an everlasting promise to him and his descendants.
20 I have heard your request about Ishmael. Yes, I will bless him, make him fertile, and increase the number of his descendants. He will be the father of 12 princes, and I will make him a great nation.
