Psalms 33:1

Four things the psalmist expresses in these verses: I. The great desire he had that God might be praised. He did not think he did it so well himself, but that he wished others also might be employed in this work; the more the better, in this concert: it is the more like heaven. 1. Holy joy is the heart and soul of praise, and that is here pressed upon all good people (Psa 33:1): Rejoice in the Lord, you righteous; so the foregoing psalm concluded and so this begins; for all our religious exercises should both begin and end with a holy complacency and triumph in God as the best of being and best of friends. 2. Thankful praise is the breath and language of holy joy; and that also is here required of us (Psa 33:2): "Praise the Lord; speak well of him, and give him the glory due to his name." 3. Religious songs are the proper expressions of thankful praise; those are here required (Psa 33:3): "Sing unto him a new song, the best you have, not that which by frequent use is worn, thread-bare, but that which, being new, is most likely to move the affections, a new song for new mercies and upon every new occasion, for those compassions which are new every morning.
