Ezekiel 24:11-13

Complete Jewish Bible

¹¹ Put the empty pot on the coals,
heat it till its copper bottom glows,
till its impurity melts inside it,
and its scum is burned away.
¹² But the effort is in vain:
its layers of scum will not leave it;
so into the fire with its scum!
¹³ Because of your filthy lewdness,
because you refused to be purified
when I wanted to purify you;
now you will not be purified from your filth
until I have satisfied my fury on you.
