Genesis 17:1-7 New Revised Standard Version, Anglicised (NRSVA)
The Sign of the Covenant
17 When Abram was ninety-nine years old, the Lord appeared to Abram, and said to him, ‘I am God Almighty;[a] walk before me, and be blameless. 2 And I will make my covenant between me and you, and will make you exceedingly numerous.’ 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,[b] but your name shall be Abraham;[c] 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[d] after you.
