Genesis 17:5-7

MSB(i) 5 No longer will you be called Abram, but your name will be Abraham, for I have made you a father of many nations. 6 I will make you exceedingly fruitful; I will make nations of you, and kings will descend from you. 7 I will establish My covenant as an everlasting covenant between Me and you and your descendants after you, to be your God and the God of your descendants after you.
