The heavens and their host proclaim the majesty of God, Psa 19:1-6; the excellence and perfection of the Divine law, Psa 19:7-10; its usefulness, Psa 19:11. The psalmist prays for pardon and preservation from sin, Psa 19:12, Psa 19:13; and thy his Words and thoughts may be holy, Psa 19:14.
The title of this Psalm has nothing particular in it; but it is not very clear that it was written by David, to whom it is attributed; though some think that he composed it in the wilderness, while persecuted by Saul. For this opinion, however, there is no solid ground. There is no note in the Psalm itself to lead us to know when, where, or by whom it was written. It is a highly finished and beautiful ode.
Verse 1
The heavens declare the glory of God - Literally, The heavens number out the glory of the strong God. A first view of the starry heavens strikes every beholder with astonishment at the power by which they were made, and by which they are supported. To find out the wisdom and skill displayed in their contrivance requires a measure of science: but when the vast magnitude of the celestial bodies is considered, we feel increasing astonishment at these works of the strong God.
The firmament - The whole visible expanse; not only containing the celestial bodies above referred to, but also the atr, light, rains, dews, etc., etc. And when the composition of these principles is examined, and their great utility to the earth and its inhabitants properly understood, they afford matter of astonishment to the wisest mind, and of adoration and gratitude even to the most unfeeling heart.
