'Circumcise' in the Bible

You must circumcise the flesh of your foreskin to serve as a sign of the covenant between Me and you.

Therefore, circumcise your hearts and don’t be stiff-necked any longer.

The Lord your God will circumcise your heart and the hearts of your descendants, and you will love Him with all your heart and all your soul so that you will live.

At that time the Lord said to Joshua, “Make flint knives and circumcise the Israelite men again.”

Circumcise yourselves to the Lord;remove the foreskin of your hearts,men of Judah and residents of Jerusalem.Otherwise, My wrath will break out like fireand burn with no one to extinguish itbecause of your evil deeds.
