Genesis Chapter 17 verses 9-14. .. Just sayin....... 9 And God said to Abraham, "As for you, you shall keep my covenant, you and your descendants after you throughout their generations. 10 This is my covenant, which you shall keep, between me and you and your descendants after you: Every male among you shall be circumcised. 11 You shall be circumcised in the flesh of your foreskins, and it shall be a sign of the covenant between me and you. 12 He that is eight days old among you shall be circumcised; every male throughout your generations, whether born in your house, or bought with your money from any foreigner who is not of your offspring, 13 both he that is born in your house and he that is bought with your money, shall be circumcised. So shall my covenant be in your flesh an everlasting covenant. 14 Any uncircumcised male who is not circumcised in the flesh of his foreskin shall be cut off from his people; he has broken my covenant."
