|Genesis 17:16-19 |
16 And I will bless her, and give you a son by her also. Yes, I will bless her, and she shall be a mother of nations; kings of people shall come from her."
17 Then Abraham fell upon his face and laughed and said in his heart, "Shall a child be born to a man who is a hundred years old? And shall Sarah, who is ninety years old, bear a son?"
18 And Abraham said to God, "O that Ishmael might live before you!"
19 And God said, "Sarah your wife shall indeed bear you a son, and you shall call his name Isaac; and I will establish my covenant with him for an everlasting covenant and with his descendants after him.
