19. Jehovah hath established his throne in the heavens. David having recounted the benefits by which God lays each of us in particular, and also the whole Church, under obligation to him, now extols in general his infinite glory. The amount is, that whenever God is mentioned, men should learn to ascend in their contemplations above the whole world, because his majesty transcends the heavens; and they should farther learn not to measure his power by that of man, since it has under its control all kingdoms and dominions. That none may think that earthly creatures only are here put in subjection to God, the Psalmist chiefly addresses the angels. In calling upon them to join in praising God, he teaches both himself and all the godly, that there is not a better nor a more desirable exercise than to praise God, since there is not a more excellent service in which even the angels are employed. The angels are doubtless too willing and prompt in the discharge of this duty, to stand in need of incitement from us. With what face then, it may be said, can we, whose slothfulness is so great, take it upon us to exhort them? But although these exalted beings run swiftly before us, and we with difficulty come lagging after them, yet David enjoins them to sing God's praises for our sake, that by their example he may awaken us from our drowsiness. The object he has in view, as I have adverted to before, is to be noted, which is, by addressing his discourse to the angels to teach us, that the highest end which they propose to themselves is to advance the divine glory. Accordingly, while in one sentence he clothes them with strength, in the immediately following, he describes them as hanging on God's word, waiting for his orders, -- Ye who do his commandment. However great the power, as if he had said, with which you are endued, you reckon nothing more honorable than to obey God. And it is not only said that they execute God's commandments, but to express more distinctly the promptitude of their obedience, it is asserted, that they are always ready to perform whatever he commands them.

21. Bless Jehovah, all ye his hosts. By hosts is not to be understood the stars, as some explain it. The subject of the preceding verse is still continued. Nor is the repetition superfluous; for the word hosts teaches us that there are myriads of myriads who stand before the throne of God, ready to receive every intimation of his will. Again, they are called his ministers who do his pleasure, to intimate to us, that they are not there intent in idly beholding God's glory, but that having been appointed as our ministers and guardians, they are always ready for their work. Instead of word, the term pleasure is here used, and both are employed with much propriety; for although the sun, the moon, and the stars, observe the laws which God has ordained for them, yet being without understanding, they cannot properly be said to obey his word and his voice. The term obey is indeed sometimes transferred to the mute and insensible parts of creation. ² It is, however, only in a metaphorical sense that they can be said to hearken to God's voice, when by a secret instinct of nature they fulfill his purposes. But this in the proper sense is true of angels, who actively obey him upon their understanding from his sacred mouth what he would have them to do. The word pleasure expresses more plainly a joyful and cheerful obedience, implying that the angels not only obey God's commandments, but also willingly and with the greatest delight receive the intimations of his will, that they may perform what he would have them to do. Such is the import of the Hebrew noun, as has been stated elsewhere.

22. Bless Jehovah, all ye his works. The Psalmist in conclusion addresses all creatures; for although they may be without speech and understanding, yet they ought in a manner to re-echo the praises of their Creator. This he does on our account, that we may learn that there is not a corner in heaven or on earth where God is not praised. We have less excuse, if, when all the works of God by praising their Maker reproach us for our sloth we do not at least follow their example. The express mention of all places of his dominion, seems to be intended to stir up the faithful to greater ardor in this exercise; for if even those countries where his voice is unheard ought not to be mute in his praise, how can we lawfully remain silent to whom he opens his mouth, anticipating us by his own sacred voice? In short, David shows that his design in recounting God's benefits, and magnifying the extent of his empire, was to animate himself the more to the exercise of praising him.
