Jeremiah 4:2-4

American Standard Version

² and thou shalt swear, As Jehovah liveth, in truth, in justice, and in righteousness; and the nations shall bless themselves in him, and in him shall they glory. ³ For thus saith Jehovah to the men of Judah and to Jerusalem, Break up your fallow ground, and sow not among thorns.

⁴ Circumcise yourselves to Jehovah, and take away the foreskins of your heart, ye men of Judah and inhabitants of Jerusalem; lest my wrath go forth like fire, and burn so that none can quench it, because of the evil of your doings.
