Genesis 17:1-7

Now 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. I will establish My covenant between Me and you, And I will multiply you exceedingly.” Abram fell on his face, and God talked with him, saying, “As for Me, behold, My covenant is with you, And you will be the father of a multitude of nations. No longer shall your name be called Abram, But your name shall be Abraham; For I have made you the father of a multitude of nations. I will make you exceedingly fruitful, and I will make nations of you, and kings will come forth from you. I will establish My covenant between Me and you and your descendants after you throughout their generations for an everlasting covenant, to be God to you and to your descendants after you.
