Psalm 89

PSALM 89Ps 89:1-52. Of Ethan—(See on [625]Ps 88:1, title). This Psalm was composed during some season of great national distress, perhaps Absalom's rebellion. It contrasts the promised prosperity and perpetuity of David's throne (with reference to the great promise of 2Sa 7:12-17), with a time when God appeared to have forgotten His covenant. The picture thus drawn may typify the promises and the adversities of Christ's kingdom, and the terms of confiding appeal to God provided appropriate prayers for the divine aid and promised blessing.1. mercies—those promised (Isa 55:3; Ac 13:34), and—faithfulness—that is, in fulfilling them.

89:1-4 Though our expectations may be disappointed, yet God's promises are established in the heavens, in his eternal counsels; they are out of the reach of opposers in hell and earth. And faith in the boundless mercy and everlasting truth of God, may bring comfort even in the deepest trials.

PSALM 89 Many psalms that begin with complaint and prayer end with joy and praise, but this begins with joy and praise and ends with sad complaints and petitions; for the psalmist first recounts God’s former favours, and then with the consideration of them aggravates the present grievances. It is uncertain when it was penned; only, in general, that it was at a time when the house of David was woefully eclipsed; some think it was at the time of the captivity of Babylon, when king Zedekiah was insulted over, and abused, by Nebuchadnezzar, and then they make the title to signify no more than that the psalm was set to the tune of a song of Ethan the son of Zerah, called Maschil; others suppose it to be penned by Ethan, who is mentioned in the story of Solomon, who, outliving that glorious prince, thus lamented the great disgrace done to the house of David in the next reign by the revolt of the ten tribes. I. The psalmist, in the joyful pleasant part of the psalm, gives glory to God, and takes comfort to himself and his friends. This he does more briefly, mentioning God’s mercy and truth (v. 1) and his covenant (v. 2-4), but more largely in the following verses, wherein, 1. He adores the glory and perfection of God (v. 5–14). 2. He pleases himself in the happiness of those that are admitted into communion with him (v. 15–18). 3. He builds all his hope upon God’s covenant with David, as a type of Christ (v. 19–37). II. In the melancholy part of the psalm he laments the present calamitous state of the prince and royal family (v. 38–45), expostulates with God upon it (v. 46–49), and then concludes with prayer for redress (v. 50, 51). In singing this psalm we must have high thoughts of God, a lively faith in his covenant with the Redeemer, and a sympathy with the afflicted parts of the church.Maschil of Ethan the Ezrahite.Verses 1-4 The psalmist has a very sad complaint to make of the deplorable condition of the family of David at this time, and yet he begins the psalm with songs of praise; for we must, in every thing, in every state, give thanks; thus we must glorify the Lord in the fire. We think, when we are in trouble, that we get ease by complaining; but we do more—we get joy, by praising. Let our complaints therefore be turned into thanksgivings; and in these verses we find that which will be matter of praise and thanksgiving for us in the worst of times, whether upon a personal or a public account, 1. However it be, the everlasting God is good and true, v. 1. Though we may find it hard to reconcile present dark providences with the goodness and truth of God, yet we must abide by this principle, That God’s mercies are inexhaustible and his truth is inviolable; and these must be the matter of our joy and praise: "I will sing of the mercies of the Lord for ever, sing a praising song to God’s honour, a pleasant song for my own solace, and Maschil, an instructive song, for the edification of others." We may be for ever singing God’s mercies, and yet the subject will not be drawn dry. We must sing of God’s mercies as long as we live, train up others to sing of them when we are gone, and hope to be singing them in heaven world without end; and this is singing of the mercies of the Lord for ever. With my mouth, and with my pen (for by that also do we speak), will I make known thy faithfulness to all generations, assuring posterity, from my own observation and experience, that God is true to every word that he has spoken, that they may learn to put their trust in God, Ps. 78:6. 2. However it be, the everlasting covenant is firm and sure, v. 2-4. Here we have, (1.) The psalmist’s faith and hope: "Things now look black, and threaten the utter extirpation of the house of David; but I have said, and I have warrant from the word of God to say it, that mercy shall be built up for ever." As the goodness of God’s nature is to be the matter of our song (v. 1), so much more the mercy that is built for us in the covenant; it is still increasing, like a house in the building up, and shall still continue our rest for ever, like a house built up. It shall be built up for ever; for the everlasting habitations we hope for in the new Jerusalem are of this building. If mercy shall be built for ever, then the tabernacle of David, which has fallen down, shall be raised out of its ruins, and built up as in the days of old, Amos 9:11. Therefore mercy shall be built up for ever, because thy faithfulness shalt thou establish in the very heavens. Though our expectations are in some particular instances disappointed, yet God’s promises are not disannulled; they are established in the very heavens (that is, in his eternal counsels); they are above the changes of this lower region and out of the reach of the opposition of hell and earth. The stability of the material heavens is an emblem of the truth of God’s word; the heavens may be clouded by vapours arising out of the earth, but they cannot be touched, they cannot be changed. (2.
