23On that very day Abraham took his son Ishmael and all those born in his household or purchased with his money—every male among the members of Abraham’s household—and he circumcised them, just as God had told him.
24So Abraham was ninety-nine years old when he was circumcised,
25and his son Ishmael was thirteen;
26Abraham and his son Ishmael were circumcised on the same day.
27And all the men of Abraham’s household—both servants born in his household and those purchased from foreigners—were circumcised with him.
