Genesis 17:1-6 New Revised Standard Version (NRSV)
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.
