Genesis 17:7-8

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 1God to thee, and to thy seed after thee.

8And I give to thee, and to thy seed after thee, the land of thy sojourning, all the land of Canaan, for an everlasting possession; and I will be a 2God to them.
