This psalm was written in distress later in David’s life. It consists of meditations and prayers, showing us how to think and call upon the Lord in times of trouble. Although sorrow and fear are temptations to sin, they need not be occasions for it. Spurgeon said, “It is the mark of a true saint that his sorrows remind him of his sins, and his sorrow for sin drives him to his God.” David asks for deliverance for the best reason possible, for His goodness’ sake.
