Jeremiah 4:3-6 NIV

[3] This is what the LORD says to the people of Judah and to Jerusalem: “Break up your unplowed ground and do not sow among thorns. [4] Circumcise yourselves to the LORD, circumcise your hearts, you people of Judah and inhabitants of Jerusalem, or my wrath will flare up and burn like fire because of the evil you have done—burn with no one to quench it. [5] “Announce in Judah and proclaim in Jerusalem and say: ‘Sound the trumpet throughout the land!’ Cry aloud and say: ‘Gather together! Let us flee to the fortified cities!’ [6] Raise the signal to go to Zion! Flee for safety without delay! For I am bringing disaster from the north, even terrible destruction.”
