²³ Abraham took his son Ishmael, along with every male in Abraham’s house, all those who were born in his house, and all those who were purchased with his money, and he circumcised them by cutting off the foreskin from their flesh. He did this on that very day, just as God had said to him. ²⁴ Abraham was ninety-nine years old when the foreskin of his flesh was circumcised. ²⁵ Ishmael, his son, was thirteen years old when the foreskin of his flesh was circumcised.
