Genesis 17:23-25

New Living Translation

²³ On that very day Abraham took his son, Ishmael, and every male in his household, including those born there and those he had bought. Then he circumcised them, cutting off their foreskins, just as God had told him. ²⁴ Abraham was ninety-nine years old when he was circumcised, ²⁵ and Ishmael, his son, was thirteen.
