Jeremiah 6:28-30

New International Version

²⁸ They are all hardened rebels,^(A)
    going about to slander.^(B)
They are bronze and iron;^(C)
    they all act corruptly.
²⁹ The bellows blow fiercely
    to burn away the lead with fire,
but the refining^(D) goes on in vain;
    the wicked are not purged out.
³⁰ They are called rejected silver,^(E)
    because the Lord has rejected them.”^(F)
