Sing unto Jehovah. David, not contented with giving thanks individually, and on his own account, exhorts the faithful to unite with him, praising God, and to do this not only because it is their duty to stir up one another to this religious exercise, but because the deliverances of which he treats were worthy of being publicly and solemnly celebrated; and this is expressed more clearly in the second clause, where he commands them to be published among the nations. The meaning is, that they are not published or celebrated as they deserve, unless the whole world is filled with the renown of them. To proclaim God's doings among the nations was indeed, as it were, to sing to the deaf; but by this manner of speaking, David intended to show that the territory of Judea was too narrow to contain the infinite greatness of Jehovah's praises. He gives God this title, He who dwelleth in Sion, to distinguish him from all the false gods of the Gentiles. There is in the phrase a tacit comparison between the God who made his covenant with Abraham and Israel, and all the gods who, in every other part of the world except Judea, were worshipped according to the blinded and depraved fancies of men. It is not enough for persons to honor and reverence some deity indiscriminately or at random; they must distinctly yield to the only living and true God the worship which belongs to him, and which he commands. Moreover, as God had particularly chosen Sion as the place where his name might be called upon, David very properly assigns it to him as his peculiar dwelling-place, not that it is lawful to attempt to shut up, in any particular place, Him whom "the heaven of heavens cannot contain," (1 Kings 8:1.) but because, as we shall afterwards see, (Psalm 132:12) he had promised to make it his rest for ever. David did not, according to his own fancy, assign God a dwelling-place there; but he understood, by a revelation from heaven, that such was the pleasure of God himself, as Moses had often predicted, (Deuteronomy 12:1.) This goes far to prove what I have said before, that this psalm was not composed upon the occasion of David's victory over Goliath; for it was only towards the close of David's reign that the ark of the covenant was removed to Sion according to the commandment of God. The conjecture of some that David spake by the Spirit of prophecy of the residence of the ark on Sion, as a future event, appears to me to be unnatural and forced. Farther, we see that the holy fathers, when they resorted to Sion to offer sacrifices to God, did not act merely according to the suggestion of their own minds; but what they did proceeded from faith in the word of God, and was done in obedience to his command; and they were, therefore, approved of by him for their religious service. Whence it follows, that there is no ground whatever to make use of their example as an argument or excuse for the religious observances which superstitious men have, by their own fancy, invented for themselves. Besides, it was not enough for the faithful, in those days, to depend upon the word of God, and to engage in those ceremonial services which he required, unless, aided by external symbols, they elevated their minds above these, and yielded to God spiritual worship. God, indeed, gave real tokens of his presence in that visible sanctuary, but not for the purpose of binding the senses and thoughts of his people to earthly elements; he wished rather that these external symbols should serve as ladders, by which the faithful might ascend even to heaven. The design of God from the commencement in the appointment of the sacraments, and all the outward exercises of religion, was to consult the infirmity and weak capacity of his people. Accordingly, even at the present day, the true and proper use of them is, to assist us in seeking God spiritually in his heavenly glory, and not to occupy our minds with the things of this world, or keep them fixed in the vanities of the flesh, a subject which we shall afterwards have a more suitable opportunity of discussing more fully. And as the Lord, in ancient times, when he called himself, He who dwelleth in Sion, intended to give his people full and solid ground of trust, tranquillity, and joy; so even now, after the law has come out of Sion, and the covenant of grace has flowed to us from that fountain, let us know and be fully persuaded, that wherever the faithful, who worship him purely and in due form, according to the appointment of his word, are assembled together to engage in the solemn acts of religious worship, he is graciously present, and presides in the midst of them.

Sing praises to the Lord - As the result of these views of his character, and at the remembrance of his doings. The heart of the psalmist is full of exultation and joy at the remembrance of the divine interposition, and he naturally breaks out into these strong expressions, calling on others to rejoice also.
Which dwelleth in Zion - On the word Zion, see the notes at Psalm 2:6. Compare Psalm 3:4; Psalm 5:7. As Zion was the place where at this time the tabernacle was set up, and the worship of God was celebrated, it is spoken of as his dwelling-place.
Declare among the people his doings - Make general and wide proclamation of what he has done; that is, make him known abroad, in his true character, that others may be brought also to put their trust in him, and to Praise him.

Declare among the people his doings - It is the duty of all those who have received the salvation of God, to recommend him and his salvation to the whole circle of their acquaintance, Christians, so called, when they meet, seldom speak about God! Why is this? Because they have nothing to say.

Sing praises to the Lord, which dwelleth in Zion,.... The psalmist having determined in the strength of grace to praise the Lord himself, and show forth all his marvellous works, and given his reasons for it, both with respect to himself in particular, and with respect to the people of God in general, here calls upon others to engage in the same work; the Lord is not only to be praised, which may be done by celebrating the perfections of his nature, and the works of his hands; by giving him thanks for mercies temporal and spiritual, and by living to his glory; but his praises are to be sung by a modulation of the voice in musical notes, as the word used signifies; see Song 2:12; where the same word is used of the singing of birds; and this is to be done by the saints jointly, in concert together, as Paul and Silas in prison sang the praises of God; and there is great reason why they should join together in this work, since they share the blessings of divine grace in common together; and it is their duty to stir up one another to this service, as well as to other parts of worship: and this perfectly agrees with the exhortation to the saints, and the work they shall be employed in at the fall of Babylon, or destruction of antichrist, Revelation 14:1. Jehovah, to whom praises are to be sung, is described as the inhabitant of Zion, the ark and tabernacle being there before the temple was built, which were symbols of the divine Presence. The Targum paraphrases it, "who causeth his Shechinah to dwell in Zion"; as many of the Jewish writers interpret this psalm of Goliath, a doubt arises here about it, since in the days of Saul, and at the time of Goliath's death, Zion was in the hands of the Jebusites, and the ark of God was not there till many years afterwards; to this it is replied, that David might compose this psalm upon that occasion not immediately at that time, but after he was king of Israel, and when the ark was brought to Zion; or that he said this by a prophetic spirit, foreseeing that, God would dwell there; and Kimchi observes, that it was everywhere a received tradition among the people of Israel that the sanctuary would be built there; but however this be, certain it is that the church of God goes by the name of Zion frequently; see Psalm 2:6, Hebrews 12:22. God by his essence and power is everywhere, he fills heaven and earth, and cannot be contained in either; his glorious presence is in heaven; his gracious presence is in his church and among his people; where they dwell he dwells, and where he dwells they dwell: hence the church is called by the same name as the Lord is here, the inhabitant of Zion, Isaiah 12:6; and this description of him points out the place where his praises are to be sung, in Zion; who are to sing them, the members of the church; and the reason why, because the Lord dwells in Zion; and is there a refuge for his people, and protects them;
declare among the people his doings; what God does for the souls of men is not only to be declared among the people of God, Psalm 66:16; but also among the people of the world, when a suitable opportunity offers; and especially in the public ministry of the word; partly that the name of God may be exalted, his grace, goodness, and mercy be displayed; and partly that it might be the means of the conversion of God's chosen ones among them, Psalm 96:2; though it may be here his doings in providence are meant, his special providential care of his church and people, and his vengeance on their enemies, on Babylon; for upon the ruin of antichrist, the judgments of God, his providential dispensations towards his church and people, will be made manifest, and all nations will be called upon to fear and worship him; see Jeremiah 50:28; the word (k) which is here used signifies such deeds and actions as are the effects of thought and counsel, and which are purposely and industriously done; and whatsoever is done by the Lord, whether in a way of grace or providence, is done after the counsel of his own will; as he thought so it is, as he purposes so it comes to pass, and all things are done well and wisely, and answer the ends and designs of them.
(k) "significat tam machinationes, sive consilia", 1 Sam. ii. 3. "quam consiliorum eventus, seu opera ipsa, quomodo", Jeremiah. xxxii. 19. Gejerus.

Those who believe that God is greatly to be praised, not only desire to praise him better themselves, but desire that others may join with them. There is a day coming, when it will appear that he has not forgotten the cry of the humble; neither the cry of their blood, or the cry of their prayers. We are never brought so low, so near to death, but God can raise us up. If he has saved us from spiritual and eternal death, we may thence hope, that in all our distresses he will be a very present help to us. The overruling providence of God frequently so orders it, that persecutors and oppressors are brought to ruin by the projects they formed to destroy the people of God. Drunkards kill themselves; prodigals beggar themselves; the contentious bring mischief upon themselves: thus men's sins may be read in their punishment, and it becomes plain to all, that the destruction of sinners is of themselves. All wickedness came originally with the wicked one from hell; and those who continue in sin, must go to that place of torment. The true state, both of nations and of individuals, may be correctly estimated by this one rule, whether in their doings they remember or forget God. David encourages the people of God to wait for his salvation, though it should be long deferred. God will make it appear that he never did forget them: it is not possible he should. Strange that man, dust in his and about him, should yet need some sharp affliction, some severe visitation from God, to bring him to the knowledge of himself, and make him feel who and what he is.

(Compare Psalm 2:6; Psalm 3:4).

(Hebrews.: 9:12-13) Thus then the z-strophe summons to the praise of this God who has done, and will still do, such things. The summons contains a moral claim, and therefore applies to all, and to each one individually. Jahve, who is to be praised everywhere and by every one, is called ישׁב ציּון, which does not mean: He who sits enthroned in Zion, but He who inhabiteth Zion, Ges. 138, 1. Such is the name by which He is called since the time when His earthly throne, the ark, was fixed on the castle hill of Jerusalem, Psalm 76:3. It is the epithet applied to Him during the period of the typical kingship of promise. That Jahve's salvation shall be proclaimed from Zion to all the world, even outside Israel, for their salvation, is, as we see here and elsewhere, an idea which throbs with life even in the Davidic Psalm; later prophecy beholds its realisation in its wider connections with the history of the future. That which shall be proclaimed to the nations is called עלילותיו, a designation which the magnalia Dei have obtained in the Psalm and the prophets since the time of Hannah's song, 1-Samuel 2:3 (from עלל, root על, to come over or upon anything, to influence a person or a thing, as it were, from above, to subject them to one's energy, to act upon them).
With כּי, quod, in Psalm 9:13, the subject of the proclamation of salvation is unfolded as to its substance. The praett. state that which is really past; for that which God has done is the assumption that forms the basis of the discourse in praise of God on account of His mighty acts. They consist in avenging and rescuing His persecuted church-persecuted even to martyrdom. The אותם, standing by way of emphasis before its verb, refers to those who are mentioned afterwards (cf. Psalm 9:20): the Chethb calls them עניּים, the Keri ענוים. Both words alternate elsewhere also, the Ker at one time placing the latter, at another the former, in the place of the one that stands in the text. They are both referable to ענה to bend (to bring low, Isaiah 25:5). The neuter signification of the verb ענה = ענו, Arab.. ‛nâ, fut o., underlies the noun ענו (cf. שׁלו), for which in Numbers 12:3 there is a Ker עניו with an incorrect Jod (like שׁליו Job 21:23). This is manifest from the substantive ענוה, which does not signify affliction, but passiveness, i.e., humility and gentleness; and the noun עני is passive, and therefore does not, like ענו, signify one who is lowly-minded, in a state of ענוה, but one who is bowed down by afflictions, עני. But because the twin virtues denoted by ענוה are acquired in the school of affliction, there comes to be connected with עני - but only secondarily - the notion of that moral and spiritual condition which is aimed at by dispensations of affliction, and is joined with a suffering life, rather than with one of worldly happiness and prosperity, - a condition which, as Numbers 12:3 shows, is properly described by ענו (ταπεινός and πραΰ́ς). It shall be proclaimed beyond Israel, even among the nations, that the Avenger of blood, דּמים דּרשׁ, thinks of them (His דּרשׁים), and has been as earnest in His concern for them as they in theirs for Him. דּמים always signifies human blood that is shed by violence and unnaturally; the plur. is the plural of the product discussed by Dietrich, Abhandl. S. 40. דּרשׁ to demand back from any one that which he has destroyed, and therefore to demand a reckoning, indemnification, satisfaction for it, Genesis 9:5, then absolutely to punish, 2-Chronicles 24:22.

Zion - Whose special and gracious presence is there. People - To the heathen nations.
