Holman Christian Standard Bible

²⁵ and his son Ishmael was 13 years old when the flesh of his foreskin was circumcised. ²⁶ On that same day Abraham and his son Ishmael were circumcised. ²⁷ And all the men of his household—both slaves born in his house and those purchased with money from a foreigner—were circumcised with him.
