From these psalm titles, we learn that David wrote at least 73 psalms. (From Acts 4:25-26 and Hebrews 4:7 we learn that he also wrote Psalms 2 & 95. From 1 Chron. 16:8-36, we can surmise he also probably wrote Psalms 96, 105, & 106.) Two Levitical clans wrote 22 psalms: Asaph (and his descendants, 12 psalms: 50, 73‑83); the Sons of Korah (10 psalms: 42, 44‑49, 84, 87, & 88). Solomon wrote two (Psalms 72, 127). Ethan the Ezrahite wrote one (Psalm 89 ). Moses wrote one (Psalm 90 ). The other 51 psalms do not specify any author.
