'Unclean' in the Bible

Then I said,“Woe is me, for I am ruined!Because I am a man of unclean lips,And I live among a people of unclean lips;For my eyes have seen the King, the Lord of hosts.”

A highway will be there, a roadway,And it will be called the Highway of Holiness.The unclean will not travel on it,But it will be for him who walks that way,And fools will not wander on it.

Awake, awake,Clothe yourself in your strength, O Zion;Clothe yourself in your beautiful garments,O Jerusalem, the holy city;For the uncircumcised and the uncleanWill no longer come into you.

Depart, depart, go out from there,Touch nothing unclean;Go out of the midst of her, purify yourselves,You who carry the vessels of the Lord.

For all of us have become like one who is unclean,And all our righteous deeds are like a filthy garment;And all of us wither like a leaf,And our iniquities, like the wind, take us away.

Who sit among graves and spend the night in secret places;Who eat swine’s flesh,And the broth of unclean meat is in their pots.
