Genesis 17:12; Genesis 17:13; Genesis 17:23; Genesis 17:27; Genesis 23:18

12 And he that is eight days old shall be circumcised among you, every man child in your generations, he that is born in the house, or bought with money of any stranger, which is not of thy seed.

13 He that is born in thy house, and he that is bought with thy money, must needs be circumcised: and my covenant shall be in your flesh for an everlasting covenant.

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 foreskin in the selfsame day, as God had said unto him.

27 And all the men of his house, born in the house, and bought with money of the stranger, were circumcised with him.

18 Unto Abraham for a possession in the presence of the children of Heth, before all that went in at the gate of his city.
