Genesis 17:19-21

21st Century King James Version

¹⁹ And God said, “Sarah thy wife shall bear thee a son indeed, and thou shalt call his name Isaac; and I will establish My covenant with him for an everlasting covenant, and with his seed after him.

²⁰ And as for Ishmael, I have heard thee. Behold, I have blessed him, and will make him fruitful and will multiply him exceedingly. Twelve princes shall he beget, and I will make him a great nation.

²¹ But My covenant will I establish with Isaac, whom Sarah shall bear unto thee at this set time in the next year.”
