Jeremiah 6:27-29

New Living Translation

²⁷ “Jeremiah, I have made you a tester of metals,^[a]
    that you may determine the quality of my people.
²⁸ They are the worst kind of rebel,
    full of slander.
They are as hard as bronze and iron,
    and they lead others into corruption.
²⁹ The bellows fiercely fan the flames
    to burn out the corruption.
But it does not purify them,
    for the wickedness remains.
