Adam Clarke on Psalms 38:5

My wounds stink and are corrupt - Taking this in connection with the rest of the Psalm, I do not see that we can understand the word in any figurative or metaphorical way. I believe they refer to some disease with which he was at this time afflicted; but whether the leprosy, the small pox, or some other disorder that had attacked the whole system, and showed its virulence on different parts of the outer surface, cannot be absolutely determined.

Because of my foolishness - This may either signify sin as the cause of his present affliction, or it may import an affliction which was the consequence of that foolish levity which prefers the momentary gratification of an irregular passion to health of body and peace of mind.
