Genesis 17:2

1 When Abram was ninety-nine years old, the Lord came to him, and said, I am God, Ruler of all; go in my ways and be upright in all things,

2 And I will make an agreement between you and me, and your offspring will be greatly increased.

3 And Abram went down on his face on the earth, and the Lord God went on talking with him, and said,

4 As for me, my agreement is made with you, and you will be the father of nations without end.

5 No longer will your name be Abram, but Abraham, for I have made you the father of a number of nations.

6 I will make you very fertile, so that nations will come from you and kings will be your offspring.

7 And I will make between me and you and your seed after you through all generations, an eternal agreement to be a God to you and to your seed after you.
