Jeremiah 4:3-4

For thus saith the LORD to the men of Judah and Jerusalem, Break up your fallow ground, and sow not among thorns. Circumcise yourselves to the LORD, and take away the foreskins of your heart, ye men of Judah and inhabitants of Jerusalem: lest my fury come forth like fire, and burn that none can quench it, because of the evil of your doings.
