Genesis 17:3-7

And Abram fell on his face: and God talked with him, saying,

As for me, behold, my covenant is with thee, and thou shalt be a father of many nations.

Neither shall thy name any more be called Abram, but thy name shall be Abraham; for a father of many 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 establish my covenant between me and thee and thy seed after thee in their generations for an everlasting covenant, to be a God unto thee, and to thy seed after thee.
