Genesis 17:6-7 KJV

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

5Neither shall thy name any more be called Abram, but thy name shall be Abraham; for a father of many 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 in their generations for an everlasting covenant, to be a God unto thee, and to thy seed after thee.

8And I will give unto thee, and to thy seed after thee, the land wherein thou art a stranger, all the land of Canaan, for an everlasting possession; and I will be their God.

9And God said unto Abraham, Thou shalt keep my covenant therefore, thou, and thy seed after thee in their generations.
