'Unclean' in the Bible

Then the Lord said, “Thus will the sons of Israel eat their bread unclean among the nations where I will banish them.”

But I said, “Ah, Lord God! Behold, I have never been defiled; for from my youth until now I have never eaten what died of itself or was torn by beasts, nor has any unclean meat ever entered my mouth.”

and I pronounced them unclean because of their gifts, in that they caused all their firstborn to pass through the fire so that I might make them desolate, in order that they might know that I am the Lord.”’

In you they have uncovered their fathers’ nakedness; in you they have humbled her who was unclean in her menstrual impurity.

Her priests have done violence to My law and have profaned My holy things; they have made no distinction between the holy and the profane, and they have not taught the difference between the unclean and the clean; and they hide their eyes from My sabbaths, and I am profaned among them.

Moreover, they shall teach My people the difference between the holy and the profane, and cause them to discern between the unclean and the clean.
