Abraham and Isaac’s circumcision

23 Then Abraham took Ishmael his son, and all who were born in his house, and all who were bought with his money, every male among the men of Abraham’s house, and circumcised the flesh of their foreskin that very same day, as God had said to him. 24 Now Abraham was ninety-nine years old, when he was circumcised in the flesh of his foreskin. 25 Ishmael his son was thirteen years old, when he was circumcised in the flesh of his foreskin. 26 On this very same day was Abraham circumcised, with Ishmael his son. 27 All the men of his house, those born in the house and those bought with money from foreigners, were circumcised with him.
