Psalms 3 - Arthur Peake's Commentary on the Bible

III. A Morning Hymn of Triumph and Peace. It is a king or party leader who speaks, but who he was or when he wrote we cannot say. The conjecture in the title is of no value except as an extreme instance of failure on the part of editors to understand the Ps. before them and the real character of David their hero. There is no trace of the pathos natural in such a situation (contrast 2 Samuel 18). No tenderness mingles with the thought of victory. The Psalmist was hard beset. He cried to the God who lived in the Temple. The victory was won. The Psalmist sleeps in peace, and awakes full of trust now that his enemies have suffered a crushing defeat.
