Genesis 17:5-8

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. I will give to you and to your descendants after you, the land of your sojournings, all the land of Canaan, for an everlasting possession; and I will be their God.”
