Genesis 17:10-27

Rotherham(i) 10 This, is my covenant, which ye shall keep, betwixt me and you, and thy seed after thee,––To circumcise to you, every male: 11 So shall ye be circumcised, in the flesh of your foreskin,––So shall it become a sign of a covenant, betwixt me and you. 12 And, he that is eight days old, shall be circumcised to you, every male to your generations,––he that is born of the house, and he that is bought with silver, of any son of a stranger, who is, not of thy seed, 13 He must surely be circumcised, born of thy house, or bought with thy silver,––So shall my covenant be in your flesh, for an age–abiding covenant. 14 But, as for the uncircumcised male who shall not be circumcised in the flesh of his foreskin,––that person shall be cut off from among his people,––my covenant, hath he made void.
15 And God said unto Abraham, As for Sarai thy wife, thou shalt not call her name, Sarai,––but, Sarah, is her name; 16 And I will bless her, yea moreover will give––from her––to thee, a son,––And I will bless her, and she shall become nations. Kings of peoples, from her, shall arise. 17 And Abraham fell on his face, and laughed,––and said in his heart, To one a hundred years old, shall a child be born? And shall, even Sarah, who is ninety years old, give birth? 18 And Abraham said unto God,––Oh that, Ishmael, might live before thee! 19 And God said––Truly, Sarah thy wife, is about to bear thee a son, and thou shalt call his name, Isaac,––and I will establish my covenant with him, as an age–abiding covenant, to his seed after him. 20 Yet, as for Ishmael, I have heard thee; lo! I have blessed him, and will make him fruitful, and multiply him, exceedingly,––twelve princes, shall he beget, and I will grant him to be a great nation; 21 But, my covenant, will I establish with Isaac,––whom Sarah shall bear, to thee, by this set time, in the next year. 22 And he left off speaking with him,––and God went up from Abraham.
23 So Abraham took Ishmael his son, and all born of his house, and all bought with his silver––every male among the men of the house of Abraham,––and circumcised the flesh of their foreskin, on this selfsame day, according to that which God had spoken with him. 24 Now, 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 On this selfsame day, was Abraham circumcised,––and Ishmael his son; 27 and, all the men of his house, born of his house, and bought with silver, from the son of a stranger, were circumcised with him.
