In this psalm we have,

I.A demand of the homage of the great men of the earth to be paid to the great God. Every clap of thunder David interpreted as a call to himself and other princes to give glory to the great God. Observe, 1. Who they are that are called to this duty: "O you mighty (Psa 29:1), you sons of the mighty, who have power, and on whom that power is devolved by succession and inheritance, who have royal blood running in your veins!" It is much for the honour of the great God that the men of this world should pay their homage to him; and they are bound to do it, not only because, high as they are, he is infinitely above them, and therefore they must bow to him, but because they have their power from him, and are to use it for him, and this tribute of acknowledgment they owe to him for it. 2. How often this call is repeated; Give unto the Lord, and again, and a third time, Give unto the Lord. This intimates that the mighty men are backward to this duty and are with difficulty persuaded to it, but that it is of great consequence to the interests of God's kingdom among men that princes should heartily espouse them. Jerusalem flourishes when the kings of the earth bring their glory and honour into it, Rev 21:24. 3. What they are called to do - to give unto the Lord, not as if he needed any thing, or could be benefited by any gifts of ours, nor as if we had any thing to give him that is not his own already (Who hath first given to him?), but the recognition of his glory, and of his dominion over us, he is pleased to interpret as a gift to him: "Give unto the Lord your own selves, in the first place, and then your services. Give unto the Lord glory and strength; acknowledge his glory and strength, and give praise to him as a God of infinite majesty and irresistible power; and whatever glory or strength he has by his providence entrusted you with offer it to him, to be used for his honour, in his service. Give him your crowns; let them be laid at his feet; give him your sceptres, your swords, your keys, put all into his hand, that you, in the use of them, may be to him for a name and a praise." Princes value themselves by their glory and strength; these they must ascribe to God, owning him to be infinitely more glorious and powerful than they. This demand of homage from the mighty must be looked upon as directed either to the grandees of David's own kingdom, the peers of the realm, the princes of the tribes (and it is to excite them to a more diligent and constant attendance at God's altars, in which he had observed them very remiss), or to the neighbouring kings whom he by his sword had made tributaries to Israel and now would persuade to become tributaries to the God of Israel. Crowned heads must bow before the King of kings. What is here said to the mighty is said to all: Worship God; it is the sum and substance of the everlasting gospel, Rev 14:6, Rev 14:7. Now we have here, (1.) The nature of religious worship; it is giving to the Lord the glory due to his name, Psa 29:2. God's name is that whereby he has made himself known. There is a glory due to his name. It is impossible that we should give him all the glory due to his name; when we have said and done out best for the honour of God's name, still we come infinitely short of the merit of the subject; but when we answer that revelation which he has made of himself, with suitable affections and adorations, then we give him some of that glory which is due to his name. If we would, in hearing and praying, and other acts of devotion, receive grace from God, we must make it our business to give glory to God. (2.) The rule of the performance of religious exercises; Worship the Lord in the beauty of holiness, which denotes, [1.] The object of our worship; the glorious majesty of God is called the beauty of holiness, Ch2 20:21. In the worship of God we must have an eye to his beauty, and adore him, not only as infinitely awful and therefore to be feared above all, but as infinitely amiable and therefore to be loved and delighted in above all; especially we must have an eye to the beauty of his holiness; this the angels fasten upon in their praises, Rev 4:8. Or, [2.] The place of worship. The sanctuary then was the beauty of holiness, Psa 48:1, Psa 48:2; Jer 17:12. The beauty of the sanctuary was the exact agreement of the worship there performed with the divine appointment - the pattern in the mount. Now, under the gospel, solemn assemblies of Christians (which purity is the beauty of) are the places where God is to be worshipped. Or, [3.] The manner of worship. We must be holy in all our religious performances, devoted to God, and to his will and glory. There is a beauty in holiness, and it is that which puts an acceptable beauty upon all the acts of worship.

II.Good reason given for this demand. We shall see ourselves bound to give glory to God if we consider,

1.His sufficiency in himself, intimated in his name Jehovah - I am that I am, which is repeated here no fewer than eighteen times in this short psalm, twice in every verse but three, and once in two of those three; I do not recollect that there is the like in all the book of psalms. Let the mighty ones of the earth know him by this name and give him the glory due to it.

2.His sovereignty over all things. Let those that rule over men know there is a God that rules over them, that rules over all. The psalmist here sets forth God's dominion,

(1)In the kingdom of nature. In the wonderful effects of natural causes, and the operations of the powers of nature, we ought to take notice of God's glory and strength, which we are called upon to ascribe to him; in the thunder, and lightning, and rain, we may see, [1.] His glory. It is the God of glory that thunders (thunders is the noise of his voice, Job 37:2), and it declares him a God of glory, so awful is the sound of the thunder, and so bright the flash of its companion, the lightning; to the hearing and to the sight nothing is more affecting than these, as if by those two learning senses God would have such proofs of his glory to the minds of men as should leave the most stupid inexcusable. Some observe that there were then some particular reasons why thunder should be called the voice of the Lord, not only because it comes from above, is not under the direction or foresight of any man, speaks aloud, and reaches far, but because God often spoke in thunder, particularly at Mount Sinai, and by thunder discomfited the enemies of Israel. To speak it the voice of the God of glory, it is here said to be upon the water, upon many waters (Psa 29:3); it reaches over the vast ocean, the waters under the firmament; it rattles among the thick clouds, the waters above the firmament. Every one that hears the thunder (his ear being made to tingle with it) will own that the voice of the Lord is full of majesty (Psa 29:4), enough to make the highest humble (for none can thunder with a voice like him) and the proudest tremble - for, if his voice be so terrible, what is his arm? Every time we hear it thunder, let our hearts be thereby filled with great, and high, and honourable thoughts of God, in the holy adorings and admirings of whom the power of godliness does so much consist. O Lord our God! thou art very great. [2.] His power (Psa 29:4.): The voice of the Lord is powerful, as appears by the effects of it; for it works wonders. Those that write natural histories relate the prodigious effects of thunder and lightning, even out of the ordinary course of natural causes, which must be resolved into the omnipotence of the God of nature. First, Trees have been rent and split by thunderbolts, Psa 29:5, Psa 29:6. The voice of the Lord, in the thunder, often broke the cedars, even those of Lebanon, the strongest, the stateliest. Some understand it of the violent winds which shook the cedars, and sometimes tore off their aspiring tops. Earthquakes also shook the ground itself on which the trees grew, and made Lebanon and Sirion to dance; the wilderness of Kadesh also was in like manner shaken (Psa 29:8), the trees by winds, the ground by earthquakes, and both by thunders, of which I incline rather to understand it. The learned Dr. Hammond understands it of the consternations and conquest of neighbouring kingdoms that warred with Israel and opposed David, as the Syrians, whose country lay near the forest of Lebanon, the Amorites that bordered on Mount Hermon, and the Moabites and Ammonites that lay about the wilderness of Kadesh. Secondly. Fires have been kindled by lightnings and houses and churches thereby consumed; hence we read of hot thunderbolts (Psa 78:48); accordingly the voice of the Lord, in the thunder, is here said to divide the flames of fire (Psa 29:7), that is, to scatter them upon the earth, as God sees fit to direct them and do execution by them. Thirdly, The terror of thunder makes the hinds to calve sooner, and some think more easily, than otherwise they would. The hind is a timourous creature, and much affected with the noise of thunder; and no marvel, when sometimes proud and stout men have been made to tremble at it. The emperor Caligula would hide himself under his bed when it thundered. Horace, the poet, owns that he was reclaimed from atheism by the terror of thunder and lightning, which he describes somewhat like this of David, lib. 1, ode 34. The thunder is said here to discover the forest, that is, it so terrifies the wild beasts of the forest that they quit the dens and thickets in which they hid themselves are so are discovered. Or it throws down the trees, and so discovers the ground that was shaded by them. Whenever it thunders let us think of this psalm; and, whenever we sing this psalm, let us think of the dreadful thunder-claps we have sometimes heard, and thus bring God's words and his works together, that by both we may be directed and quickened to give unto him the glory due unto his name; and let us bless him that there is another voice of his besides this dreadful one, by which God now speaks to us, even the still small voice of his gospel, the terror of which shall not make us afraid.

(2)In the kingdom of providence, Psa 29:10. God is to be praised as the governor of the world of mankind. He sits upon the flood; he sits King for ever. He not only sits at rest in the enjoyment of himself, but he sits as King in the throne which he has prepared in the heavens (Psa 103:19), where he takes cognizance of, and gives orders about, all the affairs of the children of men, and does all according to his will, according to the counsel of his will. Observe, [1.] The power of his kingdom: He sits upon the flood. As he has founded the earth, so he has founded his own throne, upon the floods, Psa 24:2. The ebbings and flowings of this lower world, and the agitations and revolutions of the affairs in it, give not the least shake to the repose nor to the counsels of the Eternal Mind. The opposition of his enemies is compared to the flood (Psa 93:3, Psa 93:4); but the Lord sits upon it; he crushes it, conquers it, and completes his own purposes in despite of all the devices that are in men's hearts. The word here translated the flood is never used but concerning Noah's flood; and therefore some think it is that which is here spoken of. God did sit upon that flood as a Judge executing the sentence of his justice upon the world of the ungodly that was swept away by it. And he still sits upon the flood, restraining the waters of Noah, that they turn not again to cover the earth, according to his promise never to destroy the earth any more by a flood, Gen 9:11; Isa 54:9. [2.] The perpetuity of his kingdom; He sits King for ever; no period can, or shall, be put to his government. The administration of his kingdom is consonant to his counsels from eternity and pursuant to his designs for eternity.

(3)In the kingdom of grace. Here his glory shines most brightly, [1.] In the adorations he receives from the subjects of that kingdom (Psa 29:9). In his temple, where people attend his discoveries of himself and his mind and attend him with their praises, every one speaks of his glory. In the world every man sees it, or at least may behold it afar off (Job 36:25); but it is only in the temple, in the church, that it is spoken of to his honour. All his works do praise him (that is, they minister matter for praise), but his saints only do bless him, and speak of his glory of his works, Psa 145:10. [2.] In the favours he bestows upon the subjects of that kingdom, Psa 29:11. First, He will qualify them for his service: He will give strength to his people, to fortify them against every evil work and to furnish them for every good work; out of weakness they shall be made strong; nay, he will perfect strength in weakness. Secondly, He will encourage them in his service: He will bless his people with peace. Peace is a blessing of inestimable value, which God designs for all his people. The work of righteousness is peace (great peace have those that love thy law); but much more the crown of righteousness: the end of righteousness is peace; it is endless peace. When the thunder of God's wrath shall make sinners tremble the saints shall lift up their heads with joy.

The Lord sitteth upon the flood,.... Noah's flood; which is always designed by the word here used, the Lord sat and judged the old world for its wickedness, and brought a flood upon them, and destroyed them; and then he abated it, sent a wind to assuage the waters, stopped up the windows of heaven, and the fountains of the great deep, and restrained rain from heaven; and he now sits upon the confidence of waters in the heavens, at the time of a thunder storm, which threatens with an overflowing flood; and he remembers his covenant, and restrains them from destroying the earth any more: and he sits upon the floods of ungodly men, and stops their rage and fury, and suffers them not to proceed to overwhelm his people and interest; and so the floods of afflictions of every kind, and the floods of Satan's temptations, and of errors and heresies, are at his control, and he permits them to go so far, and no farther;

yea, the Lord sitteth King for ever: he is King of the whole world, over angels and men, and even the kings of the earth; and he is also King of saints, in whose hearts he reigns by his Spirit and grace; and the Gospel dispensation is more eminently his kingdom, in which his spiritual government is most visible; and this will more appear in the latter day glory, when the Lord shall be King over all the earth; and after which the Lord Christ will reign with his saints here a thousand years, and then with them to all eternity, and of his kingdom there shall be no end.

Over this terrible raging of the elements God is enthroned, directing and restraining by sovereign power; and hence the comfort of His people. "This awful God is ours, our Father and our Love."
