Genesis 17:23-27

Holman Christian Standard Bible

²³ Then Abraham took his son Ishmael and all the slaves born in his house or purchased with his money—every male among the members of Abraham’s household—and he circumcised the flesh of their foreskin on that very day, just as God had said to him. ²⁴ Abraham was 99 years old when the flesh of his foreskin was circumcised, 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.
