Psalm 69 is a prayer of distress and deliverance, that expresses David's suffering caused by his enemies. He feels like he is drowning in despair and appeals to God for help and justice against his persecutors. The psalm also contains messianic prophecies about Jesus's suffering, his zeal for God, and his crucifixion. The psalm helps us remember that personal suffering can be seen as part of God's plan and how even in deep despair, faith and praise are still possible.
