The earth is Jehovah's. We will find in many other places the children of Abraham compared with all the rest of mankind, that the free goodness of God, in selecting them from all other nations, and in embracing them with his favor, may shine forth the more conspicuously. The object of the beginning of the psalm is to show that the Jews had nothing of themselves which could entitle them to approach nearer or more familiarly to God than the Gentiles. As God by his providence preserves the world, the power of his government is alike extended to all, so that he ought to be worshipped by all, even as he also shows to all men, without exception, the fatherly care he has about them. But since he preferred the Jews to all other nations, it was indispensably necessary that there should be some sacred bond of connection between him and them, which might distinguish them from the heathen nations. By this argument David invites and exhorts them to holiness. He tells them that it was reasonable that those whom God had adopted as his children, should bear certain marks peculiar to themselves, and not be altogether like strangers. Not that he incites them to endeavor to prejudice God against others, in order to gain his exclusive favor; but he teaches them, from the end or design of their election, that they shall then have secured to them the firm and peaceful possession of the honor which God had conferred upon them above other nations, when they devote themselves to an upright and holy life. In vain would they have been collected together into a distinct body, as the peculiar people of God, if they did not apply themselves to the cultivation of holiness. In short, the Psalmist pronounces God to be the King of the whole world, to let all men know that, even by the law of nature, they are bound to serve him. And by declaring that he made a covenant of salvation with a small portion of mankind, and by the erection of the tabernacle, gave the children of Abraham the symbol of his presence, thereby to assure them of his dwelling in the midst of them, he teaches them that they must endeavor to have purity of heart and of hands, if they would be accounted the members of his sacred family. With respect to the word fullness, I admit that under it all the riches with which the earth is adorned are comprehended, as is proved by the authority of Paul; but I have no doubt that the Psalmist intends by the expression men themselves, who are the most illustrious ornament and glory of the earth. If they should fail, the earth would exhibit a scene of desolation and solitude, not less hideous than if God should despoil it of all its other riches. To what purpose are there produced so many kinds of fruit, and in so great abundance, and why are there so many pleasant and delightful countries, if it is not for the use and comfort of men? Accordingly, David explains, in the following clause, that it is principally of men that he speaks. It is his usual manner to repeat the same thing twice, and here the fullness of the earth, and the inhabitants of the world, have the same meaning. I do not, however, deny that the riches with which the earth abounds for the use of men, are comprehended under these expressions. Paul, therefore, (1-Corinthians 10:26) when discoursing concerning meats, justly quotes this passage in support of his argument, maintaining that no kind of food is unclean, because, "the earth is the Lord's, and the fullness thereof."

The earth is the Lord's - The whole world belongs to God. He is the Creator of the earth, and therefore, its Proprietor; or, in other words, "the property vests in him." It belongs to Him in a sense somewhat similar to our right of property in anything that is the production of our hands, or of our labor or skill. We claim that as our own. We feel that we have a right to use it, or to dispose of it, as we choose. No other person has a right to take it from us, or to dictate to us how we shall employ it. Thus, God, in the highest possible sense, has a right to the earth, and to all which it produces, as being all of it the creation of His hands, and the fruit of His culture and skill. He has a right to dispose of it as He pleases; by fire, or flood, or tempest; and He has an equal right to direct man in what way He shall employ that portion of the productions of the earth which may be entrusted to Him. All the right which any person has to any portion of the earth's surface, or to what is treasured up in the earth, or to what it is made to produce, is subordinate to the claims of God, and all should be yielded up at His bidding, whether He comes and claims it to be employed in His service, or whether He comes and sweeps it away by fire or flood; by the locust, or by the palmer-worm.
And the fulness thereof - All which it contains; everything which goes to "fill up" the world: animals, minerals, vegetables, people. All belong to God, and He has a right to claim them for His service, and to dispose of them as He pleases. This very language, so noble, so true, and so suitable to be made conspicuous in the eyes of human beings, I saw inscribed in a place where it seemed to be most appropriate, and most adapted to arrest and direct the thoughts of men - on the front of the Royal Exchange in London. It was well to remind the great merchants of the largest commercial city in the world of the truth which it contains; it does much to describe the character of the British nation that it should be inscribed in a place so conspicuous, and, as it were, on the wealth of that great capital.
The world - The word used here - תבל têbêl - is a poetic word, referring to the earth considered as fertile and inhabited - the "habitable" globe; the same as the Greek, οἰκουμένη oikoumenē.
And they that dwell therein - All the inhabitants of the earth, embracing men and animals of all kinds. Compare Psalm 50:10-11. God has a claim on people - upon their services, upon their talents, upon all that they can acquire by labor and skill; He has a right to all that fly in the air, or that walk the earth, or that swim in the sea. On the occasion on which it is supposed that this psalm was written, in bringing up the ark of God, and placing it in the tabernacle provided for it in the capital of the nation, no sentiment could be more appropriate than that which would recognize the universal supremacy of God.

The earth is the Lord's - He is the Creator and Governor of it; it is his own property. Men may claim districts and kingdoms of it as their property, but God is Lord of the soil.
The fullness thereof - "All its creatures." - Targum. Every tree, plant, and shrub; the silver and the gold, and the cattle on a thousand hills.
They that dwell therein - All human beings.

The earth is the Lord's, and the fulness thereof,.... The whole universe, all the terraqueous globe, both land and water, and the circumambient air, and all that is therein; the fishes of the sea, the fowls of the air, the beasts of the field, all plants and vegetables that spring out of the earth, and metals and minerals in the bowels of it; all which are the riches of the Lord the earth is full of, Psalm 104:24; see Psalm 50:10;
the world, and they that dwell therein; the habitable world, and the dwellers on it, rational and irrational. These words may be interpreted of Christ, who is Lord of all; he made the world, and has a right and claim to all things in it; for the same person is here spoken of as in the preceding psalm, under the character of a shepherd; and this shows him to be very fit and proper for such an office, seeing he cannot fail of feeding and protecting his sheep; nor can they want any good thing, since the fulness both of nature and of grace is with him; and hence it is that all things are theirs, whether the world, or things present, or things to come; and though they seem to have nothing, yet possess all things, they possessing him whose all things are. The apostle makes use of this passage of Scripture, to prove, explain, and direct in the use of Christian liberty, with respect to the free use of creatures, they all being the Lord's; and therefore good, and to be received with thanksgiving: and yet, inasmuch as there is a variety of them, such should be abstained from, when to use them serves to embolden evil men in their wicked ways, or offend and grieve weak Christians, 1-Corinthians 10:25.

We ourselves are not our own; our bodies, our souls, are not. Even those of the children of men are God's, who know him not, nor own their relation to him. A soul that knows and considers its own nature, and that it must live for ever, when it has viewed the earth and the fulness thereof, will sit down unsatisfied. It will think of ascending toward God, and will ask, What shall I do, that I may abide in that happy, holy place, where he makes his people holy and happy? We make nothing of religion, if we do not make heart-work of it. We can only be cleansed from our sins, and renewed unto holiness, by the blood of Christ and the washing of the Holy Ghost. Thus we become his people; thus we receive blessing from the Lord, and righteousness from the God of our salvation. God's peculiar people shall be made truly and for ever happy. Where God gives righteousness, he designs salvation. Those that are made meet for heaven, shall be brought safe to heaven, and will find what they have been seeking.

God's supreme sovereignty requires a befitting holiness of life and heart in His worshippers; a sentiment sublimely illustrated by describing His entrance into the sanctuary, by the symbol of His worship--the ark, as requiring the most profound homage to the glory of His Majesty. (Psalm 24:1-10)
fulness--everything.
world--the habitable globe, with
they that dwell--forming a parallel expression to the first clause.

Jahve, whose throne of grace is now set upon Zion, has not a limited dominion, like the heathen deities: His right to sovereignty embraces the earth and its fulness (Psalm 50:12; Psalm 89:12), i.e., everything that is to be found upon it and in it.
(Note: In 1-Corinthians 10:26, Paul founds on this verse (cf. Psalm 50:12) the doctrine that a Christian (apart from a charitable regard for the weak) may eat whatever is sold in the shambles, without troubling himself to enquire whether it has been offered to idols or not. A Talmudic teacher, B. Berachoth 35a, infers from this passage the duty of prayer before meat: He who eats without giving thanks is like one who lays hands upon קדשׁי שׁמים (the sacred things of God); the right to eat is only obtained by prayer.)
For He, הוא, is the owner of the world, because its Creator. He has founded it upon seas, i.e., the ocean and its streams, נהרות, ῥέεθρα (Jonah 2:4); for the waters existed before the dry land, and this has been cast up out of them at God's word, so that consequently the solid land, - which indeed also conceals in its interior a תּהום רבּה (Genesis 7:11), - rising above the surface of the sea, has the waters, as it were, for its foundation (Psalm 136:6), although it would more readily sink down into them than keep itself above them, if it were not in itself upheld by the creative power of God. Hereupon arises the question, who may ascend the mountain of Jahve, and stand above in His holy place? The futures have a potential signification: who can have courage to do it? what, therefore, must he be, whom Jahve receives into His fellowship, and with whose worship He is well-pleased? Answer: he must be one innocent in his actions and pure in mind, one who does not lift up his soul to that which is vain (לשּׁוא, according to the Masora with Waw minusculum). (ל) נשׂא נפשׁ אל, to direct one's soul, Psalm 25:1, or longing and striving, towards anything, Deuteronomy 24:15; Proverbs 19:18; Hosea 4:8. The Ker נפשׁי is old and acknowledged by the oldest authorities.
(Note: The reading נפשׁי is adopted by Saadia (in Enumoth ii., where נפשׁי is equivalent to שׁמי), Juda ha-Levi (Cuzari iii. 27), Abulwalid (Rikma p. 180), Rashi, Kimchi, the Sohar, the Codices (and among others by that of the year 1294) and most editions (among which, the Complutensis has נפשׁי in the text). Nor does Aben-Ezra, whom Norzi has misunderstood, by any means reverse the relation of the Chethb and Ker; to him נפשׁי is the Ker, and he explains it as a metaphor (an anthropomorphism): וכתוב נפשי דוך כנוי. Elias Levita is the only one who rejects the Ker נפשׁי; but he does so though misunderstanding a Masora (vid., Baer's Psalterium p. 130) and not without admitting Masoretic testimony in favour of it (וכן ראיתי ברוב נוסחאות המסורת). He is the only textual critic who rejects it. For Jacob b. Chajim is merely astonished that נפשׁו is not to be found in the Masoreth register of words written with Waw and to be read with Jod. And even Norzi does not reject this Ker, which he is obliged to admit has greatly preponderating testimony in its favour, and he would only too gladly get rid of it.)
Even the lxx Cod. Alex. translates: τὴν ψυχὴν μου; whereas Cod. Vat. (Eus., Apollin., Theodor., et al.): τὴν ψυχὴν αὐτοῦ. Critically it is just as intangible, as it is exegetically incomprehensible; נפשׁי might then be equivalent to שׁמי. Exodus 20:7, an explanation, however, which does not seem possible even from Amos 6:8; Jeremiah 51:14. We let this Kerמ alone to its undisturbed critical rights. But that the poet did actually write thus, is incredible.
In Psalm 24:5 (just as at the close of Psalm 15:1-5), in continued predicates, we are told the character of the man, who is worthy of this privilege, to whom the question in Psalm 24:3 refers. Such an one shall bear away, or acquire (נשׁא, as e.g., Esther 2:17) blessing from Jahve and righteousness from the God of his salvation (Psalm 25:5; Psalm 27:9). Righteousness, i.e., conformity to God and that which is well-pleasing to God, appears here as a gift, and in this sense it is used interchangeably with ישׁע (e.g., Psalm 132:9, Psalm 132:16). It is the righteousness of God after which the righteous, but not the self-righteous, man hungers and thirsts; that moral perfection which is the likeness of God restored to him and at the same time brought about by his own endeavours; it is the being changed, or transfigured, into the image of the Holy One Himself. With Psalm 24:5 the answer to the question of Psalm 24:3 is at an end; Psalm 24:6 adds that those thus qualified, who may accordingly expect to receive God's gifts of salvation, are the true church of Jahve, the Israel of God. דּור (lit., a revolution, Arabic dahr, root דר, to turn, revolve) is used here, as in Psalm 14:5; Psalm 73:15; Psalm 112:2, of a collective whole, whose bond of union is not contemporaneousness, but similarity of disposition; and it is an alliteration with the דּרשׁיו (Chethb דרשו, without the Jod plur.) which follows. מבקשׁי פּניך is a second genitive depending on דּור, as in Psalm 27:8. Here at the close the predication passes into the form of invocation (Thy face). And יעקב is a summarising predicate: in short, these are Jacob, not merely after the flesh, but after the spirit, and thus in truth (Isaiah 44:2, cf. Romans 9:6; Galatians 6:16). By interpolating אלהי, as is done in the lxx and Peshto, and adopted by Ewald, Olshausen, Hupfeld, and Bttcher, the nerve, as it were, of the assertion is cut through. The predicate, which has been expressed in different ways, is concentrated intelligibly enough in the one word יעקב, towards which it all along tends. And here the music becomes forte. The first part of this double Psalm dies away amidst the playing of the instruments of the Levitical priests; for the Ark was brought in בּכל־עז וּבשׁירים, as 2-Samuel 6:5 (cf. 2-Samuel 6:14) is to be read.
