This psalm begins and ends with Hallelujah. It contains choice extracts from various psalms, which have been culled as the flowers of a garden are gathered for one bouquet. The arguments for praise are threefold: God's glory in nature, Psalms 135:5-7; His dealings with Israel, Psalms 135:8-14; the contrast of His glorious nature with idols, Psalms 135:15-21.
Notice the arguments adduced to stimulate our praise: that God is good; that praise-giving is pleasant; that He has chosen His people to be His peculiar treasure; that He is as great as He is good; that He will take our part against our foes, etc. The moral of it all is that if we would praise God aright and with zest, we must carefully gather our materials and meditate on all His dealings with us. These are fuel for the flame. But how many more reasons than the psalmist had are there for us to praise Him, who have been adopted into His family and made joint-heirs with Christ! [source]
