'Filthy' in the Bible
All of us have become like one who is unclean, and all our righteous acts are like a filthy rag; we all shrivel up like a leaf, and like the wind, our iniquities sweep us away.
"Declare and proclaim among the nations. Lift up a banner and proclaim. Don't conceal anything. Say, "Babylon will be captured. Bel will be disgraced, and Marduk will be destroyed. Her idols will be disgraced, and her filthy images will be destroyed.'
Now Joshua was wearing filthy clothes as he stood in the presence of the angel.
So the angel continued to tell those who were standing in his presence, "Remove his filthy clothes." And he told Joshua, "Look how I've removed your iniquity. Now I'm clothing you with fine garments."
