Genesis 17:23-27 - Abraham's Household Circumcised

²³ And Abraham took Ishmael his son, and all that were born in his house, and all that were bought with his money, every male among the men of Abraham's house; and circumcised the flesh of their foreskins in the same day, as God had said unto him. ²⁴ And Abraham was ninety years old and nine, when he was circumcised in the flesh of his foreskin. ²⁵ And Ishmael his son was thirteen years old, when he was circumcised in the flesh of his foreskin. ²⁶ In the same day was Abraham circumcised, and Ishmael his son. ²⁷ And all the men of his house, born in the house, and bought with money from a foreigner, were circumcised with him.
