Genesis 17:10, Genesis 17:11, Genesis 17:13, Genesis 17:14

¹⁰“^aThis is My covenant, which you shall keep, between Me and you and your seed after you: every male among you shall be circumcised.

¹¹“And ^ayou shall be circumcised in the flesh of your foreskin, and it shall be the sign of the covenant between Me and you.

¹³“A servant who is born in your house or ^awho is bought with your money shall surely be circumcised; thus shall My covenant be in your flesh for an everlasting covenant.

¹⁴“But an uncircumcised male who is not circumcised in the flesh of his foreskin, that person shall be ^acut off from his people; he has broken My covenant.”
