Although I entitle, Psalm 31 “In Adonai I Trust,” the Psalter is less than certain. A close reading of the Psalm reveals touches of doubt. Consider the closing line: “Be strong and take courage in your hearts, all who wait for Adonai.” What is the nature of the waiting? Whom is the Psalter addressing? Himself? Why has the Psalm shifted from extolling God for destroying treacherous enemies to just asking for protection? The. Psalms are subtle spiritual conversations with God.
