Genesis 17:23-27

YLT(i) 23 And Abraham taketh Ishmael his son, and all those born in his house, and all those bought with his money—every male among the men of Abraham's house—and circumciseth the flesh of their foreskin, in this self-same day, as God hath spoken with him. 24 And Abraham is a son of ninety and nine years in the flesh of his foreskin being circumcised; 25 and Ishmael his son is a son of thirteen years in the flesh of his foreskin being circumcised; 26 in this self-same day hath Abraham been circumcised, and Ishmael his son; 27 and all the men of his house—born in the house, and bought with money from the son of a stranger—have been circumcised with him.
