Psalms 38:3

This is one of the penitential psalms; it is full of grief and complaint from the beginning to the end. David's sins and his afflictions are the cause of his grief and the matter of his complaints. It should seem he was now sick and in pain, which reminded him of his sins and helped to humble him for them; he was, at the same time, deserted by his friends and persecuted by his enemies; so that the psalm is calculated for the depth of distress and a complication of calamities. He complains, I. Of God's displeasure, and of his own sin which provoked God against him (Psa 38:1-5). II. Of his bodily sickness (Psa 38:6-10). III. Of the unkindness of his friends (Psa 38:11). IV. Of the injuries which his enemies did him, pleading his good conduct towards them, yet confessing his sins against God (Psa 38:12-20). Lastly, he concludes the psalm with earnest prayers to God for his gracious presence and help (Psa 38:21, Psa 38:22). In singing this psalm we ought to be much affected with the malignity of sin; and, if we have not such troubles as are here described, we know not how soon we may have, and therefore must sing of them by way of preparation and we know that others have them, and therefore we must sing of the by way of sympathy. A psalm of David to bring to remembrance.

38:3 Sin can lead to sickness and even death (1 Cor 11:30). Whether the psalmist actually felt physically ill or his sickness was a metaphor for emotional turmoil, he knew that it came from God and threatened his life (see Pss 32:3; 39:10).
