This is one of the Hallelujah-psalms; that is the title of it, and that is the Amen of it, both its Alpha and its Omega. I. It begins with a call to praise God, particularly a call to the "servants of the Lord" to praise him, as in the foregoing psalm (Psa 135:1-3). II. It goes on to furnish us with matter for praise. God is to be praised, 1. As the God of Jacob (Psa 135:4). 2. As the God of gods (Psa 135:5). 3. As the God of the whole world (Psa 135:6, Psa 135:7). 4. As a terrible God to the enemies of Israel (Psa 135:8-11). 5. As a gracious God to Israel, both in what he had done for them and what he would do (Psa 135:12-14). 6. As the only living God, all other gods being vanity and a lie (Psa 135:15-18). III. It concludes with another exhortation to all persons concerned to praise God (Psa 135:19-21). In singing this psalm our hearts must be filled, as well as our mouths, with the high praises of God.
