My flesh is clothed with worms and clods of dust; my skin is broken, and become loathsome. My flesh is clothed with worms - This is perhaps no figure, but is literally true: the miserably ulcerated state of his body, exposed to the open air, and in a state of great destitution, was favorable to those insects that sought such places in which to deposit their ova, which might have produced the animals in question. But the figure is too horrid to be farther illustrated.
Clods of dust - I believe all the commentators have here missed the sense. I suppose Job to allude to those incrustations of indurated or dried pus, which are formed on the tops of pustules in a state of decay: such as the scales which fall from the pustules of the smallpox, when the patient becomes convalescent. Or, if Job's disease was the elephantiasis, it may refer to the furfuraceous scales which are continually falling off the body in that disorder. It is well known, that in this disease the skin becomes very rigid, so as to crack across, especially at the different joints, out of which fissures a loathsome ichor is continually exuding. To something like this the words may refer, My Skin is Broken, and become Loathsome.
