Genesis 17:17-20 Catholic Public Domain Version (CPDV)

17. Abraham fell on his face, and he laughed, saying in his heart: "Do you think a son can be born to a one hundred year old man? And will Sarah give birth at the age of ninety?"

18. And he said to God, "If only Ishmael would live in your sight."

19. And God said to Abraham: "Your wife Sarah shall give birth to a son, and you shall call his name Isaac, and I will establish my covenant with him as a perpetual covenant, and with his offspring after him.

20. Likewise, concerning Ishmael, I have heard you. Behold, I will bless and enlarge him, and I will multiply him greatly. He will produce twelve leaders, and I will make him into a great nation.
