Psalm 41 continues the theme of Psalm 38. David has recovered from his illness. Now, in this psalm, he focuses on his false friends and enemies who attacked him during his illness. He prays to God requite his false friends and enemies. This psalm applies to anyone who has experienced the hurt of false friends and enemies
Psalm 39 continues the theme of Psalm 38. Though the attacks of his enemies have ceased, David is still suffering physically and emotionally even to the point of death. Peering into the face of death, David become acutely aware of the brevity of life and the burden of God’s chastising hand.
In Psalm 38, David experiences God’s rejection because of sin. As a result, he despairs of his life. He is experiencing both physical and emotional pain which leads to depression. His enemies scheme against him and his friends have deserted him. He is too weak to respond to either and so the only thing he can do is to cry out to God. He begs God to have compassion, forgive his sin, and deliver him from his pain
