'Unclean' in the Bible

And I said, "Woe to me! For I am destroyed! For I [am] a man {of unclean lips}, and I [am] living among a people {of unclean lips}, for my eyes have seen the king, Yahweh of hosts!"

And a highway shall be there, and a way, and it shall be called the way of holiness. [The] unclean shall not travel through it, but it [is] for them, he who walks [on the] way; and fools shall not wander about.

Awake! Awake; put on your strength, Zion! Put on the garments of your beauty, Jerusalem, {holy city}! For [the] uncircumcised and [the] unclean shall not {continue to} enter you any longer.

Depart, depart, go out from there! You must not touch any unclean thing. Go out from the midst of it, keep clean, you who carry the vessels of Yahweh.

And we all have become like the unclean, and all our deeds of justice like a menstrual cloth, And we all wither like leaf, and our iniquities take us away like the wind.
