'Pure' in the Bible

Wash ye, make ye pure, Turn aside the evil of your doings, from before Mine eyes, Cease to do evil, learn to do good.

I make man more rare than fine gold, And a common man than pure gold of Ophir.

Turn aside, turn aside, go out thence, The unclean touch not, go out from her midst, Be ye pure, who are bearing the weapons of Jehovah.
