'Unclean' in the Bible

"How terrible it will be for me!" I cried, "because I am ruined! I'm a man with unclean lips, and I live among a people with unclean lips! And my eyes have seen the King, the LORD of the Heavenly Armies!"

"A highway will be there yes, there and people will call it "The Holy Way'. As for unclean people, they will not journey on it, but it will be for whomever is traveling on that Way not even fools will get lost.

Awake, awake! Clothe yourself with strength, O Zion! Put on your beautiful garments, O Jerusalem, the holy city, for the uncircumcised and the unclean won't enter you.

"Depart! Depart! Go out from there; touch no unclean thing; go out from the midst of her; purify yourselves, you who carry the vessels of the LORD.

All of us have become like one who is unclean, and all our righteous acts are like a filthy rag; we all shrivel up like a leaf, and like the wind, our iniquities sweep us away.
