My flesh is clothed with worms and clods of dust; my skin is broken, and become loathsome.
Clothed with worms. In elephantiasis maggots are bred in the sores. "Herod was eaten of worms" (Acts 12:23; Isaiah 14:11).
Clods of dust - clod-like scales of dirt: a crust of dried filth and accumulated corruption (Job 2:7-8).
My skin is broken and ... loathsome - rather, draws together, so as to heal up, and again breaks out with running matter (Gesenius). More simply, the Hebrew is, 'My skin rests х raaga` (H7280)] (for a time) and (again) melts away' (Psalms 58:7).
