Genesis 17:15-19

LITV(i) 15 And God said to Abraham, You shall not call your wife Sarai by her name Sarai, for Sarah shall be her name; 16 and I have blessed her and have also given to you a son from her. Yea, I have blessed her and she shall become nations; kings of people shall be from her. 17 And Abraham fell on his face and laughed. And he said in his heart, Shall one be born to a son of a hundred years? And shall Sarah bear, a daughter of ninety years? 18 And Abraham said to God, Oh that Ishmael might live before You! 19 And God said, Your wife Sarah truly shall bear you a son, and you shall call his name Isaac. And I have established My covenant with him for a perpetual covenant with his seed after him.
