Yeshayah 64:6

But we are all as the tameh (unclean thing), and kol tzidkoteinu (all our righteousness, our righteous deeds, works) are like beged iddim (filthy rags, a garment of menstruation); and we all do fade like the aleh (leaf); and avoneinu (our iniquities), like the ruach, have taken us away.
