'Unclean' in the Bible

Then said I, Woe is me! for I am undone; because I am a man of unclean lips, and I dwell in the midst of a people of unclean lips: for mine eyes have seen the King, Jehovah of hosts.

And ye shall defile the overlaying of thy graven images of silver, and the plating of thy molten images of gold: thou shalt cast them away as an unclean thing; thou shalt say unto it, Get thee hence.

And a highway shall be there, and a way, and it shall be called The way of holiness; the unclean shall not pass over it; but is shall be for the redeemed : the wayfaring men, yea fools, shall not err therein .

Awake, awake, put on thy strength, O Zion; put on thy beautiful garments, O Jerusalem, the holy city: for henceforth there shall no more come into thee the uncircumcised and the unclean.

Depart ye, depart ye, go ye out from thence, touch no unclean thing; go ye out of the midst of her; cleanse yourselves, ye that bear the vessels of Jehovah.

For we are all become as one that is unclean, and all our righteousnesses are as a polluted garment: and we all do fade as a leaf; and our iniquities, like the wind, take us away.
