Ezekiel 24:10-12

Complete Jewish Bible

¹⁰ heap on the wood, light it,
cook the meat and add the spices —
the bones can just be burned.
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!
