What does Psalm chapter 38 mean?
Psalm 38 contains references like those found in Psalm 32: depicting the effects of sin and the pain a believer feels under God's conviction. It's possible this passage was composed in response to David's sin with Bathsheba. He lured her into adultery, impregnated her, then attempted to cover the crime by arranging for her husband to die in battle (2 Samuel 12:7–9). Psalm 51 expresses David's intense remorse for this episode. Here, he described the anguish he feels due to God's corrective rebuke.This psalm begins with an appeal for God's forgiveness, and a reference to the Lord's rebuke. The first metaphor speaks of David being pierced by arrows. This is symbolic, and it suggests the other complaints areas well. The theme of the psalm is David's intense misery; he feels this because of his sin, for which God's hand is moving against him. David uses imagery of illness, weakened bones, overwhelming burdens, rotting flesh, crippling ailments, mourning, fever, and loss of strength. These symptoms are attributed to the anguish in David's heart (Psalm 38:1–8).
Despite his misery, David knows he has not been abandoned by God. He is experiencing the correction which comes through guilt and shame of sin (Hebrews 12:5–11); this causes his heart to hammer in his chest and his vision to blur. Friends have turned their backs on David, possibly due to his sin, or to his sudden collapse, or both. His enemies would relish the opportunity to take advantage of a scandal. David is all but deaf and mute, making no answer to those who criticize him. This might be because his suffering has rendered him incapable (Psalm 38:9–14).
The other possibility is that David chooses not to answer, out of humility and acceptance of God's will. He is fully aware of his sin. He recognizes that God alone can bring him out of this situation. David makes no demands, but humbly appeals to the Lord. As part of this, he openly confesses his sin and declares his repentance. He ends the psalm with another plea for God's mercy; even in this, he expresses faithful hope that God is his salvation (Psalm 38:15–22).
