'Unclean' in the Bible

"Alas for you, Scribes and Pharisees, hypocrites, for you are just like whitewashed sepulchres, the outside of which pleases the eye, though inside they are full of dead men's bones and of all that is unclean.

They had noticed that some of His disciples were eating their food with 'unclean' (that is to say, unwashed)

So the Pharisees and Scribes put the question to Him: "Why do your disciples transgress the traditions of the Elders, and eat their food with unclean hands?"

There is nothing outside a man which entering him can make him unclean; but it is the things which come out of a man that make him unclean."

"Have *you* also so little understanding?" He replied; "do you not understand that anything whatever that enters a man from outside cannot make him unclean,

"What comes out of a man," He added, "that it is which makes him unclean.

all these wicked things come out from within and make a man unclean."

He said to them, "You know better than most that a Jew is strictly forbidden to associate with a Gentile or visit him; but God has taught me to call no one unholy or unclean.

God has not called us to an unclean life, but to one of purity.

And no unclean thing shall ever enter it, nor any one who is guilty of base conduct or tells lies, but only they whose names stand recorded in the Lamb's Book of Life.

The unclean are shut out, and so are all who practise magic, all fornicators, all murderers, and those who worship idols, and every one who loves falsehood and tells lies.
