To the chief Musician, a Psalm of David. This psalm was penned by David, and inscribed to the chief musician, as others, to be used in public service, and was designed for Gospel times, as the subject of it shows; which is first, not an account of the light of nature, and then of the law of Moses, but of the Gospel of Christ; and especially as ministered in the times of the apostles, as a citation out of it in Ro 10:18, makes clear.
Ver. 1. The heavens declare the glory of God,.... By which we are to understand not the heavens literally taken, though these with the firmament are the handiworks of God, and do declare the glory of his perfections, especially his wisdom and power; these show that there is a God, and that he is a glorious one: but either Gospel churches, often signified by the kingdom of heaven, in the New Testament; the members of them being heaven-born souls, and the doctrines and ordinances ministered among them being from heaven; and there being a very great resemblance between them and heaven, in the company and communion enjoyed in them; and who declare the glory of the divine perfections, which is very great in the handiwork of their redemption; and who ascribe the glory of their whole salvation to God: or rather the apostles and first preachers of the word, as appears from Ro 10:18; who were set in the highest place in the church; had their commission, doctrine, and success from heaven; and who may be called by this name, because of the purity and solidity of their ministry, and their constancy and steadfastness in it, and because of their heavenly lives and conversations: these declared the glory of the divine perfections; such as those particularly of grace, goodness, and mercy, which are not discoverable by the light of nature or law of Moses, as, they are displayed in the salvation of men by Christ, in the forgiveness of their sins, the justification of their persons, and the gift of eternal life unto them: they taught men to ascribe the glory of salvation to God alone, Father, Son, and Spirit; they set forth in their ministry the glory of Christ, of his person, and of his offices and grace; and they showed that redemption was his handiwork, as follows:and the firmament showeth his handiwork; for the same persons may be called the firmament, since they that are wise are said to shine as the brightness of it, Da 12:3.
These were like to stars in it, and were the light of the world, and declared that redemption is the work which Christ undertook, and came into this world to perform, and which he has finished; his hands have wrought it, and his own arm has brought salvation to him.
The Targum interprets the heavens and the firmament, of such persons as contemplate the heavens, and look upon the firmament or air; and so do some other Jewish writers .
