Jeremiah 4:3-4

For thus says the LORD to the men of Judah and Jerusalem: “Break up your fallow ground, and sow not among thorns. Circumcise yourselves to the LORD; remove the foreskin of your hearts, O men of Judah and inhabitants of Jerusalem; lest my wrath go forth like fire, and burn with none to quench it, because of the evil of your deeds.”
