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).
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 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.]
He who is eight days old among you shall be circumcised, every male throughout your generations, whether born in [your] house or bought with [your] money from any foreigner not of your offspring.
He that is born in your house and he that is bought with your money must be circumcised; and My covenant shall be in your flesh for an everlasting covenant.
And I will bless her and give you a son also by her. Yes, I will bless her, and she shall be a mother of nations; kings of peoples shall come from her.
Then Abraham fell on his face and laughed and said in his heart, Shall a child be born to a man who is a hundred years old? And shall Sarah, who is ninety years old, bear a son?
But God said, Sarah your wife shall bear you a son indeed, and you shall call his name Isaac [laughter]; and I will establish My covenant or solemn pledge with him for an everlasting covenant and with his posterity after him.
And as for Ishmael, I have heard and heeded you: behold, I will bless him and will make him fruitful and will multiply him exceedingly; He will be the father of twelve princes, and I will make him a great nation. [Fulfilled in Gen. 25:12-18.]
And Abraham took Ishmael his son and all who were born in his house and all who were bought with his money, every male among [those] of Abraham's house, and circumcised [them] the very same day, as God had said to him.
