Genesis 17:2-7

2And I will make my covenant between me and thee, and will multiply thee exceedingly.

3And Abram fell on his face: and God talked with him, saying,

4As for me, behold, my covenant is with thee, and thou shalt be the father of a multitude of nations.

5Neither 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.

6And I will make thee exceeding fruitful, and I will make nations of thee, and kings shall come out of thee.

7And I will establish my covenant between me and thee and thy seed after thee throughout their generations for an everlasting covenant, to be a God unto thee and to thy seed after thee.
