Psalm 9 is the first of the acrostic Psalms, covering half of the Hebrew alphabet, with Psalm 10 covering the rest of the alphabet. There is some tension between psalms 9 and 10. Psalm 9 has a tone of victory over evil and its ancient Chaldean title suggests that it was written to celebrate David's victory over Goliath. Then, as the acrostic continues into Psalm 10, the tone becomes a lament: God seemingly stands afar off. Victory over evil may be 'here and not yet'.
