Genesis 17:10-27 And this is the covenant which you shall fully keep between me and you, and between your seed after you for their generations; every male of you shall be circumcised.

LXX2012⁽ⁱ⁾ ¹⁰ And this [is] the covenant which you shall fully keep between me and you, and between your seed after you for their generations; every male of you shall be circumcised. ¹¹ And you⌃ shall be circumcised in the flesh of your foreskin, and it shall be for a sign of a covenant between me and you. ¹² And the child of eight days [old] shall be circumcised by you, every male throughout your generations, and [the servant] born in the house and he that is bought with money, of every son of a stranger, who is not of your seed. ¹³ He that is born in your house, and he that is bought with money shall be surely circumcised, and my covenant shall be on your flesh for an everlasting covenant. ¹⁴ And the uncircumcised male, who shall not be circumcised in the flesh of his foreskin on the eighth day, that soul shall be utterly destroyed from its family, for he has broken my covenant. ¹⁵ And God said to Abraam, Sara your wife—her name shall not be called Sara, Sarrha shall be her name. ¹⁶ And I will bless her, and give you a son of her, and I will bless him, and he shall become nations, and kings of nations shall be of him. ¹⁷ And Abraam fell upon his face, and laughed; and spoke in his heart, saying, Shall there be a child to one who is a hundred years old, and shall Sarrha who is ninety years old, bear? ¹⁸ And Abraam said to God, Let this Ismael live before you. ¹⁹ And God said to Abraam, Yes, behold, Sarrha your wife shall bear you a son, and you shall call his name Isaac; and I will establish my covenant with him, for an everlasting covenant, to be a God to him and to his seed after him. ²⁰ And concerning Ismael, behold, I have heard you, and, behold, I have blessed him, and will increase him and multiply him exceedingly; twelve nations shall he beget, and I will make him a great nation. ²¹ But I will establish my covenant with Isaac, whom Sarrha shall bear to you at this time, in the next year. ²² And he left off speaking with him, and God went up from Abraam. ²³ And Abraam took Ismael his son, and all his home-born [servants], and all those bought with money, and every male of the men in the house of Abraam, and he circumcised their foreskins in the time of that day, according as God spoke to him. ²⁴ And Abraam was ninety-nine years old, when he was circumcised in the flesh of his foreskin. ²⁵ And Ismael his son was thirteen years old when he was circumcised in the flesh of his foreskin. ²⁶ And at the period of that day, Abraam was circumcised, and Ismael his son, ²⁷ and all the men of his house, both those born in the house, and those bought with money of foreign nations.
