Psalms 104:20

It is very probable that this psalm was penned by the same hand, and at the same time, as the former; for as that ended this begins, with "Bless the Lord, O my soul!" and concludes with it too. The style indeed is somewhat different, because the matter is so: the scope of the foregoing psalm was to celebrate the goodness of God and his tender mercy and compassion, to which a soft and sweet style was most agreeable; the scope of this is to celebrate his greatness, and majesty, and sovereign dominion, which ought to be done in the most stately lofty strains of poetry.

The provision he makes for the maintenance of all the creatures according to their nature (Psa 104:10-18, Psa 104:27, Psa 104:28). IV. The regular course of the sun and moon (Psa 104:19-24). V.
