'Circumcise' in the Bible

And you shall be circumcised in the flesh of your foreskins, and it shall be the sign (symbol, memorial) of the covenant between Me and you.

Then Zipporah took a flint knife and cut off the foreskin of her son and threw it at Moses’ feet, and said, “Indeed you are a husband of blood to me!”

So circumcise [that is, remove sin from] your heart, and be stiff-necked (stubborn, obstinate) no longer.

“And the Lord your God will circumcise your heart and the hearts of your descendants [that is, He will remove the desire to sin from your heart], so that you will love the Lord your God with all your heart and all your soul, so that you may live [as a recipient of His blessing].

At that time the Lord said to Joshua, “Make for yourself flint knives and circumcise the [new generation of the] sons of Israel as [was done] before.”

“Circumcise (dedicate, sanctify) yourselves to the LordAnd remove the foreskin [sins] of your heart,Men of Judah and inhabitants of Jerusalem,Or else My wrath will go forth like fire [consuming all that gets in its way]And burn and there will be no one to quench it,Because of the evil of your acts.”
