Genesis 17:7-27

7I will establish My covenant between Me and you and your 1descendants after you throughout their generations for an 2everlasting covenant, 3to be God to you and 4to your 5descendants after you. 86I will give to you and to your 7descendants after you, the land of your sojournings, all the land of Canaan, for an everlasting possession; and 8I will be their God.”

9God said further to Abraham, “Now as for you, 9you shall keep My covenant, you and your 10descendants after you throughout their generations. 1011This is My covenant, which you shall keep, between Me and you and your 12descendants after you: every male among you shall be circumcised. 11And 13you shall be circumcised in the flesh of your foreskin, and it shall be the sign of the covenant between Me and you. 12And every male among you who is 14eight days old shall be circumcised throughout your generations, a servant who is born in the house or who is bought with money from any foreigner, who is not of your 15descendants. 13A servant who is born in your house or 16who is bought with your money shall surely be circumcised; thus shall My covenant be in your flesh for an everlasting covenant. 14But an uncircumcised male who is not circumcised in the flesh of his foreskin, that person shall be 17cut off from his people; he has broken My covenant.”

15Then God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai, but 18Sarah shall be her name. 16I will bless her, and indeed I will give you 19a son by her. Then I will bless her, and she shall be a mother of nations; 20kings of peoples will 21come from her.” 17Then Abraham 22fell on his face and laughed, and said in his heart, “Will a child be born to a man one hundred years old? And 23will Sarah, who is ninety years old, bear a child?” 18And Abraham said to God, “Oh that Ishmael might live before You!” 19But God said, “No, but Sarah your wife will bear you 24a son, and you shall call his name 25Isaac; and 26I will establish My covenant with him for an everlasting covenant for his 27descendants after him. 20As for Ishmael, I have heard you; behold, I will bless him, and 28will make him fruitful and will multiply him exceedingly. 29He shall 30become the father of twelve princes, and I will make him a 31great nation. 21But My covenant I will establish with 32Isaac, whom 33Sarah will bear to you at this season next year.” 22When He finished talking with him, 34God went up from Abraham.

23Then Abraham took Ishmael his son, and all the servants who were 35born in his house and all who were bought with his money, every male among the men of Abraham’s household, and circumcised the flesh of their foreskin in the very same day, 36as God had said to him. 24Now Abraham was ninety-nine years old when 37he was circumcised in the flesh of his foreskin. 25And 38Ishmael his son was thirteen years old when he was circumcised in the flesh of his foreskin. 26In the very same day Abraham was circumcised, and Ishmael his son. 27All the men of his household, who were 39born in the house or bought with money from a foreigner, were circumcised with him.
