He who is eight days old among you shall be circumcised, every male in your generations, he who is born in the house or bought with money from any son of a foreigner who is not your seed.
And Abraham took Ishmael his son, 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 foreskins the same day, as God had spoken unto him.
