'Rag' in the Bible

You will desecrate your silver-plated idols and your gold-plated images. You will throw them away as if they were a menstrual rag, saying to them, "Get out!"

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.
