Jeremiah 4:2-4

New Catholic Bible

² and if you swear, “As the Lord lives!”
    in truth, in justice, and in uprightness,
then the nations will bless themselves by him
    and will glory in him.

Break up your unplowed ground
    and do not sow among thorns.
⁴ For the sake of the Lord be circumcised
    and remove the foreskin of your hearts,
    O men of Judah and inhabitants of Jerusalem,
or my wrath will leap forth like fire
    and burn with no one to quench it
    because of your evil deeds.
