Jeremiah 6:28-30

New Catholic Bible

²⁸ All of then are unrepentant rebels,
    comfortable in slander and corrupt without exception,
    hard as bronze and iron.
²⁹ The bellows roar
    and the lead is consumed by the fire.
In vain does the smelter do his work,
    for the wicked are not purged out.^[a]
30 They are called “rejected silver,”
    for the Lord has indeed rejected them.
