Genesis 17:17-19

American Standard Version

¹⁷ Then Abraham fell upon his face, and laughed, and said in his heart, Shall a child be born unto him that is a hundred years old? and shall Sarah, that is ninety years old, bear? ¹⁸ And Abraham said unto God, Oh that Ishmael might live before thee! ¹⁹ And God said, Nay, but Sarah thy wife shall bear thee a son; and thou shalt call his name ^[a]Isaac: and I will establish my covenant with him for an everlasting covenant for his seed after him.
