Jeremiah 4:1-5

If thou wilt return, O Israel, saith Jehovah, if thou wilt return unto me, and if thou wilt put away thine abominations out of my sight; then shalt thou not be removed; 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. For thus saith Jehovah to the men of Judah and to Jerusalem, Break up your fallow ground, and sow not among thorns. 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. Declare ye in Judah, and publish in Jerusalem; and say, Blow ye the trumpet in the land: cry aloud and say, Assemble yourselves, and let us go into the fortified cities.
