Matthew Poole and continuators on Job 7:5

5. My flesh is clothed with worms , and clods of dust ; my skin is broken , and become loathsom.

i. e. Covered all over as with a garment.

Which oft breed and break forth in divers parts of living bodies, as history and experience witnesseth, and which were easily bred out of Iob's corrupted flesh and sores.

Either the dust of the earth upon which he lay, which his sores would quickly lick up; or the scabs of his sores, which by degrees mouldred away into dust.

By Ulcers breaking forth in all parts of it.
