Genesis 17:5-6, 16

Neither shall thy name any more be called Abram, but thy name shall be Abraham; for the father of a multitude of nations have I made thee. And I will make thee exceeding fruitful, and I will make nations of thee, and kings shall come out of thee.

And I will bless her, and moreover I will give thee a son of her: yea, I will bless her, and she shall be a mother of nations; kings of peoples shall be of her.
