This and divers of the psalms that follow it seem to have been penned by David for the service of the church in their solemn feasts, and not upon any particular occasion. This is a psalm of praise. The title of it is "Hallelujah - Praise you the Lord," intimating that we must address ourselves to the use of this psalm with hearts disposed to praise God. It is composed alphabetically, each sentence beginning with a several letter of the Hebrew alphabet, in order exactly, two sentences to each verse, and three a piece to the last two. The psalmist, exhorting to praise God, I. Sets himself for an example (Psa 111:1). II. Furnishes us with matter for praise from the works of God. 1. The greatness of his works and the glory of them. 2. The righteousness of them. 3. The goodness of them. 4. The power of them. 5. The conformity of them to his word of promise. 6. The perpetuity of them. These observations are intermixed (Psa 111:2-9). III. He recommends the holy fear of God, and conscientious obedience to his commands, as the most acceptable way of praising God (Psa 111:10).
