Jeremiah 4:1-4

1If thou wilt return, O Israel, saith the LORD, return to me: and if thou wilt put away thy abominations out of my sight, then shalt thou not be removed. 2And thou shalt swear, The LORD liveth, in truth, in judgment, and in righteousness; and the nations shall bless themselves in him, and in him shall they glory.

3For thus saith the LORD to the men of Judah and Jerusalem, Break up your fallow ground, and sow not among thorns. 4Circumcise 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.
