Spiritual uncleanness because of willful disobedience to God.

The Lord shall wash away the filth of the daughters of Zion, Isa. 4: 4 (2 Ne. 14: 4). The kingdom of God is not filthy, 1 Ne. 15: 34 (Alma 7: 21). They who are filthy shall be filthy still, 2 Ne. 9: 16 (Morm. 9: 14). How will you feel, if ye shall stand before the bar of God, having your garments stained with filthiness? Alma 5: 22. They must remain filthy still, D&C 88: 35. When shall I rest, and be cleansed from filthiness? Moses 7: 48.
