Circumcise therefore the foreskin of your heart, and be no more stiffnecked.
The LORD shall send upon thee cursing, vexation, and rebuke, in all that thou settest thine hand unto for to do, until thou be destroyed, and until thou perish quickly; because of the wickedness of thy doings, whereby thou hast forsaken me.
And the LORD thy God will circumcise thine heart, and the heart of thy seed, to love the LORD thy God with all thine heart, and with all thy soul, that thou mayest live.
Behold, the days come, saith the LORD, that I will punish all them which are circumcised with the uncircumcised;
Egypt, and Judah, and Edom, and the children of Ammon, and Moab, and all that are in the utmost corners, that dwell in the wilderness: for all these nations are uncircumcised, and all the house of Israel are uncircumcised in the heart.
O house of David, thus saith the LORD; Execute judgment in the morning, and deliver him that is spoiled out of the hand of the oppressor, lest my fury go out like fire, and burn that none can quench it, because of the evil of your doings.
And if thy hand offend thee, cut it off: it is better for thee to enter into life maimed, than having two hands to go into hell, into the fire that never shall be quenched:
Where their worm dieth not, and the fire is not quenched.
For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh:
But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.
