Genesis 17:1-9

WHEN ABRAM was ninety-nine years old, the Lord appeared to him and said, I am the Almighty God; walk and live habitually before Me and be perfect (blameless, wholehearted, complete). And I will make My covenant (solemn pledge) between Me and you and will multiply you exceedingly. Then Abram fell on his face, and God said to him, As for Me, behold, My covenant (solemn pledge) is with you, and you shall be the father of many nations. Nor shall your name any longer be Abram [high, exalted father]; but your name shall be Abraham [father of a multitude], for I have made you the father of many nations. And I will make you exceedingly fruitful and I will make nations of you, and kings will come from you. And I will establish My covenant between Me and you and your descendants after you throughout their generations for an everlasting, solemn pledge, to be a God to you and to your posterity after you. [Gal. 3:16.] And I will give to you and to your posterity after you the land in which you are a stranger [going from place to place], all the land of Canaan, for an everlasting possession; and I will be their God. [Acts 7:5.] And God said to Abraham, As for you, you shall therefore keep My covenant, you and your descendants after you throughout their generations.
