Joshua 5:2

¹⁶Circumcise therefore the foreskin of your heart, and be no more stiff-necked.

⁶The LORD your God will circumcise your heart, and the heart of your offspring, to love the LORD your God with all your heart and with all your soul, that you may live.

²⁵Then Zipporah took a flint, and cut off the foreskin of her son, and cast it at his feet; and she said, “Surely you are a bridegroom of blood to me.”

¹⁰This is my covenant, which you shall keep, between me and you and your offspring after you. Every male among you shall be circumcised. ¹¹You shall be circumcised in the flesh of your foreskin. It will be a token of the covenant between me and you. ¹²He who is eight days old shall be circumcised among you, every male throughout your generations, he who is born in the house, or bought with money from any foreigner who is not of your offspring. ¹³He who is born in your house, and he who is bought with your money, must be circumcised. My covenant shall be in your flesh for an everlasting covenant. ¹⁴The 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.”

¹¹In him you were also circumcised with a circumcision not made with hands, in the putting off of the body of the sins of the flesh, in the circumcision of Christ,

¹¹He received the sign of circumcision, a seal of the righteousness of the faith which he had while he was in uncircumcision, that he might be the father of all those who believe, though they might be in uncircumcision, that righteousness might also be accounted to them.

²⁹but he is a Jew who is one inwardly, and circumcision is that of the heart, in the spirit, not in the letter; whose praise is not from men, but from God.
