So circumcise your heart, and do not stiffen your neck any longer.

“Moreover, the Lord your God will circumcise your heart and the hearts of your descendants, to love the Lord your God with all your heart and all your soul, so that you may live.

Israel Is Circumcised

Now it came about when all the kings of the Amorites who were beyond the Jordan to the west, and all the kings of the Canaanites who were by the sea, heard how the Lord had dried up the waters of the Jordan before the sons of Israel until they had crossed, that their hearts melted, and there was no spirit in them any longer because of the sons of Israel.

Circumcise yourselves to the Lord And remove the foreskins of your hearts, Men of Judah and inhabitants of Jerusalem, Or else My wrath will spread like fire And burn with no one to quench it, Because of the evil of your deeds.”
