17 When Abram was ninety-nine years old the Lord appeared to Abram and said to him, “I am God Almighty;1 walk before me, and be nblameless, 2 that I may make my covenant between me and you, and omay multiply you greatly.” 3 Then Abram pfell on his face. And God said to him, 4 “Behold, my covenant is with you, and you shall be qthe father of a multitude of nations. 5 No longer shall your name be called Abram,2 but ryour name shall be Abraham,3 sfor I have made you the father of a multitude of nations. 6 I will make you exceedingly fruitful, and I will make tyou into nations, and ukings shall come from you. 7 And I will vestablish my covenant between me and you and your offspring after you throughout their generations for an everlasting covenant, wto be God to you and to your offspring after you. 8 And xI will give to you and to your offspring after you the land of your sojournings, all the land of Canaan, for an everlasting possession, and yI will be their God.”
9 And God said to Abraham, “As for you, you shall keep my covenant, you and your offspring after you throughout their generations. 10 This is my covenant, which you shall keep, between me and you and your offspring after you: Every male among you shall be circumcised. 11 You shall be circumcised in the flesh of your foreskins, and it shall be a zsign of the covenant between me and you. 12 He who is aeight days old among you shall be circumcised. Every male throughout your generations, whether born in your house or bbought with your money from any foreigner who is not of your offspring, 13 both he who is born in your house and he who is bought with your money, shall surely be circumcised. So shall my covenant be in your flesh an everlasting covenant. 14 Any uncircumcised male who is not circumcised in the flesh of his foreskin shall be cut off from his people; he has broken my covenant.”
15 And God said to Abraham, “As for Sarai your wife, you shall not call her name Sarai, but Sarah4 shall be her name. 16 I will bless her, and moreover, I will cgive5 you a son by her. I will bless her, and dshe shall become nations; kings of peoples shall come from her.” 17 Then Abraham efell on his face fand laughed and said to himself, “Shall a child be born to a man who is a hundred years old? Shall Sarah, who is ninety years old, bear a child?” 18 And Abraham said to God, “Oh that Ishmael might live before you!” 19 God said, “No, but gSarah your wife shall bear you a son, and you shall call his name hIsaac.6 I will establish my covenant with him as an everlasting covenant for his offspring after him. 20 As for Ishmael, I have heard you; behold, I have blessed him and will make him fruitful and imultiply him greatly. He jshall father twelve princes, and kI will make him into a great nation. 21 But lI will establish my covenant with Isaac, mwhom Sarah shall bear to you at this time next year.”
22 When he had finished talking with him, nGod went up from Abraham. 23 Then Abraham took Ishmael his son and all those born in his house or bought with his money, every male among the men of Abraham's house, and he circumcised the flesh of their foreskins that very day, as God had said to him. 24 Abraham was ninety-nine years old when he was circumcised in the flesh of his foreskin. 25 And Ishmael his son was thirteen years old when he was circumcised in the flesh of his foreskin. 26 That very day Abraham and his son Ishmael were circumcised. 27 And all the men of his house, those born in the house and those bought with money from a foreigner, were circumcised with him.
