Job 13:28

28. Rotten thing Rottenness. Such as caries, or decay, in wood. The most destructive agencies work in silence. “A moth does mischief, and makes no sound; so the minds of the wicked, in that they neglect to take account of their losses, lose their soundness, as it were, without knowing it. For they lose innocency from the heart, truth from the lips, continency from the flesh, and, as time holds on, life from their age.” ST. GREGORY, Moralia.

And he Thus speaking of himself in the third person, Job paves the way to the sad estate of man as man, which forms the subject of the next chapter.
