Genesis 17:15–22

15 Then God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai, but 7Sarah shall be her name. 16 And I will bless her wand also give you a son by her; then I will bless her, and she shall be a mother xof nations; ykings of peoples shall be from her.”

17 Then Abraham fell on his face zand laughed, and said in his heart, “Shall a child be born to a man who is one hundred years old? And shall Sarah, who is ninety years old, bear a child?” 18 And Abraham asaid to God, “Oh, that Ishmael might live before You!”

19 Then God said: “No, bSarah your wife shall bear you a son, and you shall call his name Isaac; I will establish My ccovenant with him for an everlasting covenant, and with his descendants after him. 20 And as for Ishmael, I have heard you. Behold, I have blessed him, and will make him fruitful, and dwill multiply him exceedingly. He shall beget etwelve princes, fand I will make him a great nation. 21 But My gcovenant I will establish with Isaac, hwhom Sarah shall bear to you at this iset time next year.” 22 Then He finished talking with him, and God went up from Abraham.
