It is probable, Asaph was the author of this psalm; for we read of the words of David and the words of Asaph the seer, which were used in praising God in Hezekiah's time, 2 Chron. xxix, 30. He begins with laying down a general principle, ver. 1. Confesses his temptation to envy the wicked, ver. 2-14. Tells how he gained the victory over it, and advantage by it, ver. 15-28. A psalm of Asaph.
