Ezekiel 24:11-13

Amplified Bible

¹¹ 
“Then set the empty pot (Jerusalem) back on the coals
So that it may be hot
And its bronze may glow
And its filthiness may be melted
And its rust (scum) may be consumed.
¹² 
“She has wearied Me with toil,
Yet her great rust has not left her;
Her thick rust and filth will not be burned away by fire [no matter how hot the flame].
¹³ 
“In your filthiness are lewdness and outrage.
Therefore I would have cleansed you,
Yet you were not [willing to be] cleansed,
You will not be cleansed from your filthiness again
Until I have satisfied My wrath against you.
