23 Then Abraham took his son Ishmael and all his slaves, whether born in his house or acquired with his money—every male among the members of Abraham’s household—and he circumcised the flesh of their foreskins on that same day, as God had told him to do.
24 Abraham was ninety-nine years old when the flesh of his foreskin was circumcised,
25 and his son Ishmael was thirteen years old when the flesh of his foreskin was circumcised.
26 Thus, on that same day Abraham and his son Ishmael were circumcised;
27 and all the males of his household, including the slaves born in his house or acquired with his money from foreigners, were circumcised with him.
