Jeremiah 4:3-4

3For this is what the Lord says to the men of Judah and to Jerusalem, “Plow your uncultivated ground [for a season], And do not sow among thorns.

4Circumcise (dedicate, sanctify) yourselves to the Lord And remove the foreskin [sins] of your heart, Men of Judah and inhabitants of Jerusalem, Or else My wrath will go forth like fire [consuming all that gets in its way] And burn and there will be no one to quench it, Because of the evil of your acts.”
