Genesis 17:17-19

Lexham English Bible

¹⁷ And Abraham fell upon his face and laughed. And he said in his heart, “Can a child be born to a man a hundred years old,^[a] or can Sarah bear a child at ninety?”^{[b] 18} And Abraham said to God, “Oh that Ishmael might live before you!” ¹⁹ And God said, “No, but Sarah your wife shall bear a son for you, and you shall call his name Isaac. And I will establish my covenant with him as an everlasting covenant to his offspring after him.
