To the chief musician. A song of David.

David, with the view of encouraging the faithful to contemplate the glory of God, sets before them in the first place, a mirror of it in the fabric of the heavens, and in the exquisite order of their workmanship which we behold; and in the second place, he recalls our thoughts to the Law, in which God made himself more familiarly known to his chosen people. Taking occasion from this, he continues to discourse at considerable length on this peculiar gift of Heaven, commending and exalting the use of the law. Finally, he concludes the psalm with a prayer.
