For my loins are filled with a loathsome [disease]
The word here used has the signification of burning F11; and the Targum renders it, "my loins are filled with burning"; a burning fever was upon him, or there was an inflammation in those parts; a hot burning ulcer, which might be nauseous; and so was true in both senses. Aben Ezra interprets it abominable and vile; something not fit to be mentioned; and so Kimchi and Ben Melech. The word is rendered sometimes "lightly esteemed"; as in ( 1 Samuel 18:23 ) ; and Jarchi thinks it has this sense here; and the meaning is, that he was vile in his own eyes, and mean in his own esteem. Doubtless the psalmist has reference to something more than a bodily disease; at least not to that only, but to the disease of his soul also, sin, which has the nature of a disease; it is an hereditary one, which is derived from one to another by propagation; it is uersal, and reaches to all men, and to all the parts of the body and powers of the soul; it is a complication of disorders: it is in its own nature mortal, and ever incurable but by Christ; and, as here, it is a loathsome one; it is loathsome to God, and to all sensible sinners: and when the psalmist says his loins were filled with it, it may signify that it was an internal disorder that was in him; sin that dwelt in him, a law in his members; and may denote the aboundings of sin in him, the swarms of corruptions that were in him; as also the pain it gave him, and the quick sense he had of it;
and [there is] no soundness in my flesh:
which is repeated, see ( Psalms 38:3 ) ; partly for confirmation's sake, and partly to show the continued sense of it, as persons under a disorder are continually making mention of it.
