Keil & Delitzsch

On Psalms 89:1-4

The poet, who, as one soon observes, is a חכם (for the very beginning of the Psalm is remarkable and ingenious), begins with the confession of the inviolability of the mercies promised to the house of David, i.e., of the הסדי דוד הנּאמנים, Isa 55:3.

(Note: The Vulgate renders: Misericordias Domini in aeternum cantabo. The second Sunday after Easter takes its name from this rendering.)

God's faithful love towards the house of David, a love faithful to His promises, will he sing without ceasing, and make it known with his mouth, i.e., audibly and publicly (cf. Job 19:16), to the distant posterity. Instead of חסדי, we find here, and also in Lam 3:22, חסדי with a not merely slightly closed syllable. The Lamed of לדר ודר is, according to Psa 103:7; Psa 145:12, the datival Lamed. With כּי־אמרתּי (lxx, Jerome, contrary to Psa 89:3, ὅτι εἶπας) the poet bases his resolve upon his conviction. נבנה means not so much to be upheld in building, as to be in the course of continuous building (e.g., Job 22:23; Mal 3:15, of an increasingly prosperous condition). Loving-kindness is for ever (accusative of duration) in the course of continuous building, viz., upon the unshakeable foundation of the promise of grace, inasmuch as it is fulfilled in accordance therewith. It is a building with a most solid foundation, which will not only not fall into ruins, but, adding one stone of fulfilment upon another, will rise ever higher and higher. שׁמים then stands first as casus absol., and בּהם is, as in Psa 19:5, a pronoun having a backward reference to it. In the heavens, which are exalted above the rise and fall of things here below, God establishes His faithfulness, so that it stands fast as the sun above the earth, although the condition of things here below seems sometimes to contradict it (cf. Psa 119:89). Now follow in Psa 89:4-5 the direct words of God, the sum of the promises given to David and to his seed in 2 Sam. 7, at which the poet arrives more naturally in Psa 89:20. Here they are strikingly devoid of connection. It is the special substance of the promises that is associated in thought with the "loving-kindness" and "truth" of Psa 89:3, which is expanded as it were appositionally therein. Hence also אכין and תּכין, וּבניתי and יבּנה correspond to one another. David's seed, by virtue of divine faithfulness, has an eternally sure existence; Jahve builds up David's throne "into generation and generation," inasmuch as He causes it to rise ever fresh and vigorous, never as that which is growing old and feeble.

Matthew Henry

On Psalms 89:1-4

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, Psa 89:1. 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, Psa 78:6. 2. However it be, the everlasting covenant is firm and sure, Psa 89:2-4. 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 (Psa 89:1), 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, Amo 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.) An abstract of the covenant upon which this faith and hope are built: I have said it, says the psalmist, for God hath sworn it, that the heirs of promise might be entirely satisfied of the immutability of his counsel. He brings in God speaking (Psa 89:3), owning, to the comfort of his people, "I have made a covenant, and therefore will make it good." The covenant is made with David; the covenant of royalty is made with him, as the father of his family, and with his seed through him and for his sake, representing the covenant of grace made with Christ as head of the church and with all believers as his spiritual seed. David is here called God's chosen and his servant; and, as God is not changeable to recede from his own choice, so he is not unrighteous to cast off one that served him. Two things encourage the psalmist to build his faith on this covenant: - [1.] The ratification of it; it was confirmed with an oath: The Lord has sworn, and he will not repent. [2.] The perpetuity of it; the blessings of the covenant were not only secured to David himself, but were entailed on his family; it was promised that his family should continue - Thy seed will I establish for ever, so that David shall not want a son to reign (Jer 33:20, Jer 33:21); and that it should continue a royal family - I will build up thy throne to all generations, to all the generations of time. This has its accomplishment only in Christ, of the seed of David, who lives for ever, to whom God has given the throne of his father David, and of the increase of whose government and peace there shall be no end. Of this covenant the psalmist will return to speak more largely, Psa 89:19, etc.

Spurgeon's Treasury of David

About this Psalm

We have now reached the majestic Covenant Psalm, which, according to the Jewish arrangement closes the third book of the Psalms. It is the utterance of a believer, in presence of great national disaster, pleading with his God, urging the grand argument of covenant engagements, and expecting deliverance and help, because of the faithfulness of Jehovah.

TITLE. Maschil. This is most fitly called a Maschil, for it is most instructive. No subject is more important or is so fully the key to all theology as that of the covenant. He who is taught by the Holy Spirit to be clear upon the covenant of grace will be a scribe well instructed in the things of the kingdom; he whose doctrinal theory is a mingle mangle of works and grace is scarcely fit to be teacher of babes. Of Ethan the Ezrahite: perhaps the same person as Jeduthun, who was a musician in David's reign; was noted for his wisdom in Solomon's days, and probably survived till the troubles of Rehoboam's period. If this be the man, he must have written this Psalm in his old age, when troubles were coming thick and heavy upon the dynasty of David and the land of Judah; this is not at all improbable, and there is much in the Psalm which looks that way.

DIVISION. The sacred poet commences by affirming his belief in the faithfulness of the Lord to his covenant with the house of David, and makes his first pause at Ps 89:4. He then praises and magnifies the name of the Lord for his power, justice, and mercy, Ps 89:5-14. This leads him to sing of the happiness of the people who have such a God to be their glory and defence, Ps 89:15-18. He rehearses the terms if the covenant at full length with evident delight, Ps 89:19-37, and then mournfully pours out his complaint and petition, Ps 89:38-51, closing the whole with a hearty benediction and a double Amen. May the Holy Spirit greatly bless to us the reading of this most precious Psalm of instruction .

Exposition

I will sing of the mercies of the Lord for ever. A devout resolve, and very commendable when a man is exercised with great trouble on account of an apparent departure of the Lord from his covenant and promise. Whatever we may observe abroad or experience in our own persons, we ought still to praise God for his mercies, since they most certainly remain the same, whether we can perceive them or not. Sense sings but now and then, but faith is an eternal songster. Whether others sing or not, believers must never give over; in them should be constancy of praise, since God's love to them cannot by any possibility have changed, however providence may seem to frown. We are not only to believe the Lord's goodness, but to rejoice in it evermore; it is the source of all our joy, and as it cannot be dried up, so the stream ought never to fail to flow, or cease to flash in sparkling crystal of song. We have not one, but many mercies to rejoice in, and should therefore multiply the expressions of our thankfulness. It is Jehovah who deigns to deal out to us our daily benefits, and he is the all sufficient and immutable God; therefore our rejoicing in him must never suffer diminution. By no means let his exchequer of glory be deprived of the continual revenue which we owe to it. Even time itself must not bound our praises-they must leap into eternity; he blesses us with eternal mercies-let us sing unto him forever.

With my mouth will I make known thy faithfulness to all generations. The utterances of the present will instruct future generations. What Ethan sung is now a text book for Christians, and will be so as long as this dispensation shall last. We ought to have an eye to posterity in all that we write, for we are the schoolmasters of succeeding ages. Ethan first spoke with his mouth that which he recorded with his pen-a worthy example of using both means of communication; the mouth has a warmer manner than the pen, but the pen's speech lives longest, and is heard farther and wider. While reading this Psalm, such in the freshness of the style, that one seems to hear it gushing from the poet's mouth; he makes the letters live and talk, or, rather, sing to us. Note, that in this second sentence he speaks of faithfulness, which is the mercy of God's mercies-the brightest jewel in the crown of goodness. The grace of an unfaithful God would be a poor subject for music, but unchangeable love and immutable promises demand everlasting songs. In times of trouble it is the divine faithfulness which the soul hangs upon; this is the bower anchor of the soul, its hold fast, and its stay. Because God is, and ever will be, faithful, we have a theme for song which will not be out of date for future generations; it will never be worn out, never be disproved, never be unnecessary, never be an idle subject, valueless to mankind. It will also be always desirable to make it known, for men are too apt to forget it, or to doubt it, when hard times press upon them. We cannot too much multiply testimonies to the Lord's faithful mercy-if our own generation should not need them others will: sceptics are so ready to repeat old doubts and invent new ones that believers should be equally prompt to bring forth evidences both old and new. Whoever may neglect this duty, those who are highly favoured, as Ethan was, should not be backward.

Tyndale Study Notes

On Psalms 89:1-2

Ps 89 Book Three (Pss 73-89) begins and ends with weighty questions. Though Ps 89 begins with a praise-filled account of how the Lord exalted the throne of David (89:1-37), the psalmist protests the Lord’s apparent rejection of his covenant with David (89:38-51; see 2 Sam 7:8-16).

89:title Ethan the Ezrahite was a wise man (1 Kgs 4:31; cp. Ps 88:title).

89:1 God’s unfailing love gives reason to celebrate forever.
