Ezekiel 24:11-13

New Catholic Bible

¹¹ Stand the empty pot on the coals
    so that it may become red-hot,
until the copper glows
    and the filth inside it melts,
    and its rust is consumed.
¹² Yet not even with fire
    will its rust disappear.
¹³ And when I expended my efforts
    to cleanse you of your filthy lewdness,
you did not allow yourself
    to be purged of your filth.
Now you shall not again be cleansed
    until I have exhausted my anger upon you.
