(9) I have preached.--Literally, I have made countenances glad.

Notice the rapid succession of clauses, like successive wave-beats of praise, better than any elaborate description to represent the feelings of one whose life was a thanksgiving.

Verse 9. - I have preached righteousness in the great congregation: rather, I have proclaimed righteousness. David has sung the praises of God in the "great congregation," and extolled his righteousness and truth (Psalm 35:18). He has not "preached," in the modern sense of the word, since the preaching office was reserved for the priests and Levites. Lo, I have not refrained my lips; or, I will not refrain my lips. I will continue to glorify thee openly, and praise thy Name while I have my being (Psalm 104:33). O Lord, thou knowest; i.e. thou knowest the truth of my statement as to the past, and the sincerity of my promise as to the future.

40:6-10 The psalmist foretells that work of wonder, redemption by our Lord Jesus Christ. The Substance must come, which is Christ, who must bring that glory to God, and that grace to man, which it was impossible the sacrifices should ever do. Observe the setting apart of our Lord Jesus to the work and office of Mediator. In the volume, or roll, of the book it was written of him. In the close rolls of the Divine decrees and counsel, the covenant of redemption was recorded. Also, in all the volumes of the Old Testament something was written of him, Joh 19:28. Now the purchase of our salvation is made, the proclamation is sent forth, calling us to come and accept it. It was preached freely and openly. Whoever undertook to preach the gospel of Christ, would be under great temptation to conceal it; but Christ, and those he calls to that work, are carried on in it. May we believe his testimony, trust his promise, and submit to his authority.I have preached righteousness in the great congregation,.... Not the righteousness which the law requires men to do; but the righteousness which Christ himself wrought out, for the justification of them that believe; this he was a preacher, as well as the author of, and is part of the glad tidings he was anointed to preach, Isaiah 61:1; and the word (n) here used signifies, for the most part, the publishing of good tidings; and this our Lord did publicly, before all the people, in the synagogues of the Jews, and in the temple, whither the people in great numbers resorted; especially at the three great festivals in the year; the feasts of passover, pentecost, and tabernacles, when all the males were obliged to appear, and made up a great congregation indeed; see John 2:23;

lo, I have not refrained my lips, O Lord, thou knowest; Christ appeals to his divine Father, the searcher of hearts, and trier of reins, for the truth of this; that he had not laid any restraint upon his lips, nor kept back anything in his ministry that was profitable; but had taught the way of God in great integrity and sincerity; had opened his mouth, and spoke freely and fully, and used great plainness of speech.
