You shall be circumcised in the flesh of your foreskin. It will be a token of the covenant between me and you.

The uncircumcised male who is not circumcised in the flesh of his foreskin, that soul shall be cut off from his people. He has broken my covenant."

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 foreskin in the same day, as God had said to him.

Abraham was ninety-nine years old, when he was circumcised in the flesh of his foreskin.

Ishmael, his son, was thirteen years old when he was circumcised in the flesh of his foreskin.
