Genesis 17:1-6

1 And when Abram was ninety years old and nine, the LORD appeared to Abram, and said to him, I am the Almighty God; walk before me, and be you perfect.

2 And I will make my covenant between me and you, and will multiply you exceedingly.

3 And Abram fell on his face: and God talked with him, saying,

4 As for me, behold, my covenant is with you, and you shall be a father of many nations.

5 Neither shall your name any more be called Abram, but your name shall be Abraham; for a father of many nations have I made you.

6 And I will make you exceeding fruitful, and I will make nations of you, and kings shall come out of you.
