Genesis 17 American Standard Version (ASV)
17 And when Abram was ninety years old and nine, Jehovah appeared to Abram, and said unto him, I am [a]God Almighty; walk before me, and be thou perfect. 2 And I will make my covenant between me and thee, and will multiply thee exceedingly. 3 And Abram fell on his face: and God talked with him, saying, 4 As for me, behold, my covenant is with thee, and thou shalt be the father of a multitude of nations. 5 Neither shall thy name any more be called [b]Abram, but thy name shall be [c]Abraham; for the father of a multitude of nations have I made thee. 6 And I will make thee exceeding fruitful, and I will make nations of thee, and kings shall come out of thee. 7 And I will establish my covenant between me and thee and thy seed after thee throughout their generations for an everlasting covenant, to be a God unto thee and to thy seed after thee. 8 And I will give unto thee, and to thy seed after thee, the land of thy sojournings, all the land of Canaan, for an everlasting possession; and I will be their God.
9 And God said unto Abraham, And as for thee, thou shalt keep my covenant, thou, and thy seed after thee throughout their generations. 10 This is my covenant, which ye shall keep, between me and you and thy seed after thee: every male among you shall be circumcised. 11 And ye shall be circumcised in the flesh of your foreskin; and it shall be a token of a covenant betwixt me and you. 12 And he that is eight days old shall be circumcised among you, every male throughout your generations, he that is born in the house, or bought with money of any foreigner that is not of thy seed. 13 He that is born in thy house, and he that is bought with thy money, must needs be circumcised: and my covenant shall be in your flesh for an everlasting covenant. 14 And the uncircumcised male who is not circumcised in the flesh of his foreskin, that soul shall be cut off from his people; he hath broken my covenant.
15 And God said unto Abraham, As for Sarai thy wife, thou shalt not call her name Sarai, but [d]Sarah shall her name be. 16 And I will bless her, and moreover I will give thee a son of her: yea, I will bless her, and she shall be a mother of nations; kings of peoples shall be of her. 17 Then Abraham fell upon his face, and laughed, and said in his heart, Shall a child be born unto him that is a hundred years old? and shall Sarah, that is ninety years old, bear? 18 And Abraham said unto God, Oh that Ishmael might live before thee! 19 And God said, Nay, but Sarah thy wife shall bear thee a son; and thou shalt call his name [e]Isaac: and I will establish my covenant with him for an everlasting covenant for his seed after him. 20 And as for Ishmael, I have heard thee: behold, I have blessed him, and will make him fruitful, and will multiply him exceedingly; twelve princes shall he beget, and I will make him a great nation. 21 But my covenant will I establish with Isaac, whom Sarah shall bear unto thee at this set time in the next year.
22 And he left off talking with him, and God went up from Abraham. 23 And Abraham took Ishmael his son, and all that were born in his house, and all that were bought with his money, every male among the men of Abraham’s house, and circumcised the flesh of their foreskin in the selfsame day, as God had said unto him. 24 And Abraham was ninety years old and nine, 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 In the selfsame day was Abraham circumcised, and Ishmael his son. 27 And all the men of his house, those born in the house, and those bought with money of a foreigner, were circumcised with him.
Genesis 17 New International Version (NIV)
The Covenant of Circumcision
17 When Abram was ninety-nine years old, the Lord appeared to him and said, “I am God Almighty[a]; walk before me faithfully and be blameless. 2 Then I will make my covenant between me and you and will greatly increase your numbers.”
3 Abram fell facedown, and God said to him, 4 “As for me, this is my covenant with you: You will be the father of many nations. 5 No longer will you be called Abram[b]; your name will be Abraham,[c] for I have made you a father of many nations. 6 I will make you very fruitful; I will make nations of you, and kings will come from you. 7 I will establish my covenant as an everlasting covenant between me and you and your descendants after you for the generations to come, to be your God and the God of your descendants after you. 8 The whole land of Canaan, where you now reside as a foreigner, I will give as an everlasting possession to you and your descendants after you; and I will be their God.”
9 Then God said to Abraham, “As for you, you must keep my covenant, you and your descendants after you for the generations to come. 10 This is my covenant with you and your descendants after you, the covenant you are to keep: Every male among you shall be circumcised. 11 You are to undergo circumcision, and it will be the sign of the covenant between me and you. 12 For the generations to come every male among you who is eight days old must be circumcised, including those born in your household or bought with money from a foreigner—those who are not your offspring. 13 Whether born in your household or bought with your money, they must be circumcised. My covenant in your flesh is to be an everlasting covenant. 14 Any uncircumcised male, who has not been circumcised in the flesh, will be cut off from his people; he has broken my covenant.”
15 God also said to Abraham, “As for Sarai your wife, you are no longer to call her Sarai; her name will be Sarah. 16 I will bless her and will surely give you a son by her. I will bless her so that she will be the mother of nations; kings of peoples will come from her.”
17 Abraham fell facedown; he laughed and said to himself, “Will a son be born to a man a hundred years old? Will Sarah bear a child at the age of ninety?” 18 And Abraham said to God, “If only Ishmael might live under your blessing!”
19 Then God said, “Yes, but your wife Sarah will bear you a son, and you will call him Isaac.[d] I will establish my covenant with him as an everlasting covenant for his descendants after him. 20 And as for Ishmael, I have heard you: I will surely bless him; I will make him fruitful and will greatly increase his numbers. He will be the father of twelve rulers, and I will make him into a great nation. 21 But my covenant I will establish with Isaac, whom Sarah will bear to you by this time next year.” 22 When he had finished speaking with Abraham, God went up from him.
23 On that very day Abraham took his son Ishmael and all those born in his household or bought with his money, every male in his household, and circumcised them, as God told him. 24 Abraham was ninety-nine years old when he was circumcised, 25 and his son Ishmael was thirteen; 26 Abraham and his son Ishmael were both circumcised on that very day. 27 And every male in Abraham’s household, including those born in his household or bought from a foreigner, was circumcised with him.
