And he as a rotten thing consumeth,.... This by some Jewish writers (z) is referred to and connected with the driven leaf and dry stubble Job compares himself to, Job 13:25; and so the sense is, that his body, which, for its frailty and weakness, is compared to such things, is like any rotten thing, a rotten tree, as Ben Melech; or any thing else that is rotten, that is consuming and wasting away, as Job's body was, being clothed with worms and clods of dust: as a garment that is moth eaten; a woollen garment, which gathers dust, out of which motifs arise; for dust, in wool and woollen garments produces moths, as Aristotle (a) and Pliny (b) observe; and a garment eaten by them, slowly, gradually, and insensibly, yet certainly, decays, falls to pieces, becomes useless, and not to be recovered; such was Job's body, labouring under the diseases it did, and was every day more and more decaying, crumbling into dust, and just ready to drop into the grave; so that there was no need, and it might seem cruel, to lay greater and heavier afflictions on it: some interpreters make this "he" to be God himself who sometimes is as rottenness and a moth to men, in their persons, families, and estates; see Hos 5:12.
