Psalm LXXXIX
1Understand, beloved, this Psalm, which I am about to explain, by the grace of God, of our hope in the Lord Jesus Christ, and be of good cheer, because He who promised, will fulfil all, as He has fulfilled much: for it is not our own merit, but His mercy, that gives us confidence in Him. He Himself is meant, in my belief, by “the understanding of Æthan the Israelite:” which has given this Psalm its title. You see then, who is meant by Æthan: but the meaning of the word is “strong.” No man in this world is strong, except in the hope of God’s promises: for as to our own deservings, we are weak, in His mercy we are strong. Weak then in himself, strong in God’s mercy, the Psalmist thus begins: “I will sing of Thy mercies, O Lord, for ever: with my mouth will I make known Thy truth unto all generations” (ver. 1).
2Let my limbs, he saith, serve the Lord: I speak, but it is of Thine I speak. “With my mouth will I make known Thy truth:” if I obey not Thee, I am not Thy servant: if I speak on my own part, I am a liar. To speak then from Thee, and in my own person, are two things: one mine, one Thine: Truth Thine, language mine. Let us hear then what faithfulness he maketh known, what mercies he singeth.
3“For Thou hast said, Mercy shall be built up for ever” (ver. 2). It is this that I sing: this is Thy truth, for the making known of which my mouth serveth. In such wise Thou sayest, I build, as not to destroy: for some Thou destroyest and buildest not; and some whom Thou destroyest Thou dost rebuild. For unless there were some who were destroyed to be rebuilt, Jeremiah would not have written, “See, I have this day set thee to throw down and to build.” And indeed all who formerly worshipped images and stones could not be built up in Christ, without being destroyed as to their old error. While, unless some were destroyed not to be built up, it would not be written, “He shall destroy them, and not build them up.” … In what follows, he joins these two words, mercy and faithfulness; “For Thou hast said, Mercy shall be built up for ever: Thy truth shall be established in the Heavens:” in which mercy and truth are repeated, “for all the ways of the Lord are mercy and truth,” for truth in the fulfilment of promises could not be shown, unless mercy in the remission of sins preceded. Next, as many things were promised in prophecy even to the people of Israel that came according to the flesh from the seed of Abraham, and that people was increased that the promises of God might be fulfilled in it; while yet God did not close the fountain of His goodness even to the Gentiles, whom He had placed under the rule of the Angels, while He reserved the people of Israel as His own portion: the Apostle expressly mentions the Lord’s mercy and truth as referring to these two parties. For he calls Christ “a minister of the Circumcision for the truth of God, to confirm the promises made unto the fathers.” See how God deceived not; see how He cast not off His people, whom He foreknew.
For while the Apostle is treating of the fall of the Jews, to prevent any from believing them so far disowned of God, that no wheat from that floor’s fanning could reach the granary, he saith, “God hath not cast away His people, whom He foreknew; for I also am an Israelite.” If all that nation are thorns, how am I who speak unto you wheat? So that the truth of God was fulfilled in those Israelites who believed, and one wall from the circumcision is thus brought to meet the corner stone. But this stone would not form a corner, unless it received another wall from the Gentiles:
so that the former wall relates in a special manner to the truth, the latter to the mercy of God.
“Now I say,” says the Apostle, “that Jesus Christ was a minister of the Circumcision for the truth of God, to confirm the promise made unto the fathers: and that the Gentiles might glorify God for His mercy.” Justly then is it added, “Thy truth shalt Thou stablish in the Heavens:” for all those Israelites who were called to be Apostles became as Heavens which declare the glory of God: as it is written by them, “The Heavens declare the glory of God, and the firmament showeth His handywork.” …Since, although they were taken up from hence before the Church filled the whole world, yet as “their words reached to the ends of the world,” we are right in supposing this which we have just read, “Thy truth shalt Thou stablish in the Heavens,” fulfilled in them.
4“Thou hast said, I have made a covenant with My chosen” (ver. 3). What covenant, but the new, by which we are renewed to a fresh inheritance, in our longing desire and love of which we sing a new song. “I have made a covenant with My chosen,” saith the Psalmist: “I have sworn unto David My servant.” How confidently does he speak, who understands, whose mouth serves truth! I speak without fear; since “Thou hast said.” If Thou makest me fearless, because Thou hast said, how much more so dost Thou make me, when Thou hast sworn! For the oath of God is the assurance of a promise. Man is justly forbidden to swear: lest by the habit of swearing, since a man may be deceived, he fall into perjury. God alone swears securely, because He alone is infallible.
5Let us see then what God hath sworn. “I have sworn,” He saith, “to David My servant; thy seed will I establish for ever” (ver. 4). But what is the seed of David, but that of Abraham. And what is the seed of Abraham? “And to thy seed,” He saith, “which is Christ.” But perhaps that Christ, the Head of the Church, the Saviour of the body, is the seed of Abraham, and therefore of David; but we are not Abraham’s seed? We are assuredly; as the Apostle saith, “And if ye be Christ’s, then are ye Abraham’s seed, and heirs according to the promise.” In this sense, then, let us take the words, brethren, “Thy seed will I stablish for ever,” not only of that Flesh of Christ, born of the Virgin Mary, but also of all of us who believe in Christ, for we are limbs of that Head. This body cannot be deprived of its Head: if the Head is in glory for ever, so are the limbs, so that Christ remains entire for ever. “Thy seed will I stablish for ever: and set up thy throne to generation and generation.” We suppose he saith, “for ever,” because it is “to generation and generation:” since he has said above, with “my mouth will I ever be showing Thy truth to generation and generation.” What is “to generation and generation”? To every generation: for the word needed not as many repetitions, as the coming and passing away of the several generations. The multiplication of generations is signified and set forth to notice by the repetition. Are possibly two generations to be understood, as ye are aware, my beloved brethren, and as I have before explained? for there is now a generation of flesh and blood: there will be a future generation in the resurrection of the dead. Christ is proclaimed here: He will be proclaimed there: here He is proclaimed, that He may be believed in: there, He will be welcomed, that He may be seen.
“I will set up Thy throne from one generation to another.” Christ hath now a throne in us, His throne is set up in us: for unless he sat enthroned within us, He would not rule us: but if we were not ruled by Him, we should be thrown down by ourselves. He therefore sits within us, reigning over us: He sits also in another generation, which will come from the resurrection of the dead. Christ will reign for ever over His Saints. God has promised this; He hath said it: if this is not enough, God hath sworn it.
As then the promise is certain, not on account of our deservings, but of His pity, no one ought to be afraid in proclaiming that which he cannot doubt of. Let that strength then inspire our hearts, whence Æthan received his name, “strong in heart:” let us preach the truth of God, the utterance of God, His promises, His oath; and let us, strengthened on every side by these means, glorify God, and by bearing Him along with us, become Heavens.
6“O Lord, the very Heavens shall praise Thy wondrous works” (ver. 5). The Heavens will not praise their own merits, but Thy wondrous works, O Lord. For in every act of mercy on the lost, of justification of the unrighteous, what do we praise but the wondrous works of God? Thou praisest Him, because the dead have risen: praise Him yet more, because the lost are redeemed. What grace, what mercy of God! Thou seest a man yesterday a whirlpool of drunkenness, to-day an ornament of sobriety: a man yesterday the sink of luxury, to-day the beauty of temperance: yesterday a blasphemer of God, to-day His praiser: yesterday the slave of the creature, to-day the worshipper of the Creator. From all these desperate states men are thus converted: let them not look at their own merits: let them become Heavens, and praise the wondrous works of Him by whom they were made Heavens.…
7“For who is he among the clouds, who shall be compared unto Thee, Lord!” (ver. 6). Is this to be the praise of the Heavens, is this to be their rain? What? are the preachers confident, because “none among the clouds shall be compared unto the Lord”? Does it appear to you, brethren, a high ground of praise, that the clouds cannot be compared with their Creator? If it is taken in its literal, not in its mystical meaning, it is not so: what? are the stars that are above the clouds to be compared with the Lord? what? can the Sun, Moon, Angels, Heavens, be even compared with the Lord? Why is it then that he says, as if he meant some high praise, “For who is he among the clouds?” etc. We understand, my brethren, those clouds, as the Heavens, to be the preachers of truth; Prophets, Apostles, the announcers of the word of God.…If therefore the clouds are the preachers of the truth, let us first enquire why they are clouds. For the same men are Heavens and clouds: Heavens from the brightness of the truth, clouds from the hidden things of the flesh: for all clouds are obscure, owing to their mortality: and they come and go. It is on account of these very obscurities of the flesh, that is, of the clouds, that the Apostle saith, “Therefore judge nothing before the time, until the Lord come, who will bring to light the hidden things of darkness.”
