Genesis 17:1-6 RSV

1 When Abram was ninety-nine years old the LORD appeared to Abram, and said to him, "I am God Almighty; walk before me, and be blameless.
2 And I will make my covenant between me and you, and will multiply you exceedingly."
3 Then Abram fell on his face; and God said to him,
4 "Behold, my covenant is with you, and you shall be the father of a multitude of nations.
5 No longer shall your name be Abram, but your name shall be Abraham; for I have made you the father of a multitude of nations.
6 I will make you exceedingly fruitful; and I will make nations of you, and kings shall come forth from you.
