'Clean' in the Bible

“I have seen your vile and detestable acts,Even your adulteries and your lustful neighings [after idols],And the lewdness of your prostitutionOn the hills in the fields.Woe (judgment is coming) to you, O Jerusalem!How long will you remain unclean [by ignoring My precepts]?”

Sharpen the arrows, take up the shields [and cover yourselves]!The Lord has stirred up the spirit of the kings of the Medes,Because His purpose concerning Babylon is to destroy it;For that is the vengeance of the Lord, vengeance [on Babylon] for [plundering and destroying] His temple.

The Lord of hosts has sworn [an oath] by Himself, saying,“Surely I will fill you with men, as with [a swarm of] locusts [who strip the land clean],And they will lift up a song and shout of victory over you.”
