Genesis 17:3-9 New Revised Standard Version (NRSV)
3 Then Abram fell on his face; and God said to him, 4 “As for me, this is my covenant with you: You shall be the ancestor of a multitude of nations. 5 No longer shall your name be Abram,[a] but your name shall be Abraham;[b] for I have made you the ancestor of a multitude of nations. 6 I will make you exceedingly fruitful; and I will make nations of you, and kings shall come from you. 7 I will establish my covenant between me and you, and your offspring after you throughout their generations, for an everlasting covenant, to be God to you and to your offspring[c] after you. 8 And I will give to you, and to your offspring after you, the land where you are now an alien, all the land of Canaan, for a perpetual holding; and I will be their God.”
9 God said to Abraham, “As for you, you shall keep my covenant, you and your offspring after you throughout their generations.
