5. Exalt Jehovah our God. This exhortation is properly addressed to the Church alone, because having been made a partaker of the grace of God, she ought the more zealously to devote herself to his service, and to the love of godliness. The Psalmist, therefore, calls upon the Jews to exalt that God from whom they had received such manifest help, and enjoins them to render that worship appointed in his Law. The temple indeed is frequently in other places denominated God's seat, or house, or rest, or dwelling-place; here it is called his footstool, and for the use of this metaphor, there is the best of all reasons. For God desired to dwell in the midst of his people in such a manner, as not only to direct their thoughts to the outward temple and to the ark of the covenant, but rather to elevate them to things above. Hence the term house or dwelling-place tended to impart courage and confidence to them, that all the faithful might have boldness to draw near unto God freely, whom they beheld coming to meet them of his own accord.

But as the minds of men are prone to superstition, it was necessary to check this propensity, lest they should associate with their notions of God things fleshly and earthly, and their thoughts should be wholly engrossed by the outward forms of worship. The prophet, therefore, in calling the temple God's footstool, desires the godly to elevate their thoughts above it, for he fills heaven and earth with his infinite glory. Nevertheless, by these means he reminds us that true worship can be paid to God no where else than upon mount Zion. For he employs a style of writing such as is calculated to elevate the minds of the godly above the world, and, at the same time, does not in the least degree detract from the holiness of the temple, which alone of all places of the earth God had chosen as the place where he was to be worshipped. From this we may see, since the days of Augustine, how vainly many perplex themselves in endeavoring to ascertain the reason for the prophet ordering God's footstool to be worshipped. The answer of Augustine is ingenious. If, says he, we look to Christ's manhood, we will perceive a reason why we may worship the footstool of God, and yet not be guilty of idolatry; for that body in which he wishes to be worshipped he took from the earth, and on this earth nothing else than God is worshipped, for the earth is both the habitation of Deity, and God himself condescended to become earth. All this is very plausible, but it is foreign to the design of the prophet, who, intending to distinguish between legal worship, (which was the only worship that God sanctioned,) and the superstitious rites of the heathen, summons the children of Abraham to the temple, as if to their standard, there, after a spiritual manner, to worship God, because he dwells in celestial glory.

Now that the shadowy dispensation has passed away, I believe that God cannot otherwise be properly worshipped, than when we come to him directly through Christ, in whom all the fullness of the Godhead dwells. It were improper and absurd for any one to designate him a footstool. For the prophet merely spake in this manner to show that God was not confined to the visible temple, but that he is to be sought for above all heavens, ³inasmuch as he is elevated above the whole world.

The frantic bishops of Greece, in the second Council of Nice, very shamefully perverted this passage, when they endeavored to prove from it that God was to be worshipped by images and pictures. The reason ⁴ assigned for exalting Jehovah our God, and worshipping at his footstool, contains an antithesis: he is holy. For the prophet, in hallowing the name of the one God, declares all the idols of the heathen to be unholy; as if he should say, Although the heathen claim for their idols an imaginary sanctity, they are nevertheless very vanity, an offense, and abomination. Some translate this clauses for it is holy; but it will appear from the end of the psalm that it was the design of the prophet by this title to distinguish God from all idols.

6. Moses and Aaron. The Psalmist magnifies the special grace which God in a very remarkable manner vouchsafed to the seed of Abraham, that thence he chose for himself prophets and priests to be, as it were, mediators between him and the people, to ratify the covenant of salvation. And he mentions three persons who were famous in former times. For Moses was, as it were, a mediator to reconcile the people unto God. Aaron was invested with the same office; and, subsequently, Samuel sustained the same character. There is no doubt, however, that under these three persons he included all the people with whom God had made a covenant. But he mentions the names of those who were the depositaries and guardians of this invaluable treasure. It may appear improper that he should speak of Moses as among the priests, since his sons were only among the common Levites, and that Moses himself, after the giving of the law, never held the office of high priest. But as the Hebrews call Mynhwk, chohanim, those who are chief and very eminent personages, ⁵ such as kings' sons, there is nothing to prevent the prophet from giving this designation to Moses, as if he had said that he was one of the holy rulers of the Church. ⁶ Moreover, if we go back to the first original -- to the period prior to the publication of the law, it is certain that Moses was then invested with the high priest's office. The design of the prophet must also be kept in mind, namely, that God not only adopted the seed of Abraham, but set apart some of them to act as mediators, whom he enjoined to call upon his name, in order that his covenant might be the more confirmed. For the invocation of which he speaks must not be understood indiscriminately of every manner of calling upon, but only of that which belongs to the priests, who were chosen by God, as intercessors to appear in his presence in the name of all the people, and to speak on their behalf.

They called upon Jehovah. The Psalmist explains more fully what I have just now said, that God from the very first, and with a special reference to his gracious covenant, bestowed great benefits upon the descendants of Abraham -- the Jews. And, therefore, as often as they experienced the loving-kindness of God, it behooved them to call to mind his former loving-kindness. The prophet, too, makes particular mention of the visible symbol of the cloudy pillar, by which God designed to testify in all ages that his presence was ever with his people, according as he employed temporal signs, not only for their benefit to whom they were exhibited, but also for the benefit of those who were to succeed them. Not that God always showed a cloudy pillar to his ancient people, but considering that the dullness of men is so great, that they do not perceive the presence of God unless they are put in mind by external signs, the prophet very properly reminds the Jews of this memorable token. And as God had appeared openly in the desert to their fathers, so their posterity might be well assured that he would also be near to them. He adds, that they had kept God's testimonies, for the purpose of enforcing the duty of like obedience upon succeeding generations.

8. O Jehovah our God. The prophet here reminds them that God had heard their prayers because his grace and their piety harmonized. Consequently, encouraged by their exemplary success in prayer, their posterity ought to call upon God, not merely pronouncing his name with their lips, but keeping his covenant with all their heart. He farther reminds us that if God does not display his glory so bountifully, and so profusely in every age, the fault is with men themselves, whose posterity have either utterly forsaken, or greatly declined from the faith of the fathers. It is not to be wondered at that God should withdraw his hand, or at least not stretch it forth in any remarkable way, when he beholds piety waxing cold on the earth.

O God, thou hast been propitious to them.⁷ From these words it is quite obvious that what the Psalmist had formerly said concerning Moses, Aaron, and Samuel, refers to the whole people; for surely they did not officiate as priests merely for their own benefit, but for the common benefit of all the Israelites. Hence the transition is more natural which he makes from these three to the remaining body of the people. For I neither restrict the relative, to these three persons, nor do I interpret them exclusively of the same, but I rather think that the state of the whole Church is pointed out; namely, that while God, at the prayers of the priests, was propitious to the Jews, he, at the same time, sharply punished them for their sins. For on the one hand, the prophet magnifies the grace of God in that he had treated the people so kindly, and had so mercifully forgiven their iniquity; on the other hand, he specifies those awful examples of punishment by which he punished them for their ingratitude, that their descendants might learn to submit themselves dutifully to him. For it must not be forgotten, that by how much God deals graciously with us, by so much will he the less easily endure that we should treat his liberality with scorn.

In the close of the psalm he repeats the same sentence which we had in the fifth verse, only substituting his holy mountain instead of his footstool; and as for the sake of brevity he had formerly said somewhat obscurely awh swdq, kadosh hu, he is holy, he now says more plainly, Jehovah our God is holy. His intention is to show that God is not to be worshipped by the Israelites at random, (as the religion of the heathen depended upon fancy alone,) but that his worship is founded upon the assurance of faith.
