'Unclean' in the Bible

And I say, 'Woe to me, for I have been silent, For a man -- unclean of lips am I, And in midst of a people unclean of lips I am dwelling, Because the King, Jehovah of Hosts, have my eyes seen.'

And a highway hath been there, and a way, And the 'way of holiness' is called to it, Not pass over it doth the unclean, And He Himself is by them, Whoso is going in the way -- even fools err not.

Awake, awake, put on thy strength, O Zion, Put on the garments of thy beauty, Jerusalem -- the Holy City; For enter no more into thee again, Do the uncircumcised and unclean.

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.

And we are as unclean -- all of us, And as a garment passing away, all our righteous acts; And we fade as a leaf -- all of us. And our iniquities as wind do take us away.
