Jeremiah 4:2-4

Revised Standard Version

² and if you swear, ‘As the Lord lives,’
    in truth, in justice, and in uprightness,
then nations shall bless themselves in him,
    and in him shall they glory.”

“Break up your fallow ground,
    and sow not among thorns.
⁴ Circumcise yourselves to the Lord,
    remove the foreskin of your hearts,
    O men of Judah and inhabitants of Jerusalem;
lest my wrath go forth like fire,
    and burn with none to quench it,
    because of the evil of your doings.”
