Say unto God, How terrible are thy works, O Lord! in the multitude of thy strength thy enemies shall lie to thee.

“"Say ye to God, How to be feared are Your works!" [Psalm 66:3]. Wherefore to be feared and not to be loved? Hear another voice of a Psalm: "Serve the Lord in fear, and exult unto Him with trembling." What means this? Hear the voice of the Apostle: "With fear," he says, "and trembling, work out your own salvation." [Philippians 2:12] Wherefore with fear and trembling? He has subjoined the reason: "for God it is that works in you both to will and to work according to good will." [Philippians 2:13] If therefore God works in you, by the Grace of God you work well, not by your strength. Therefore if you rejoice, fear also: lest perchance that which was given to a humble man be taken away from a proud one....Brethren, if against the Jews of old, cut off from the root of the Patriarchs, we ought not to exalt ourselves, but rather to fear and say to God, "How to be feared are Your works:" how much less ought we not to exalt ourselves against the fresh wounds of the cutting off! Before there had been cut off Jews, graffed in Gentiles; from the very graft there have been cut off heretics; but neither against them ought we to exalt ourselves; lest perchance he deserve to be cut off, that delights to revile them that are cut off. My brethren, a bishop's voice, however unworthy, has sounded to you: we pray you to beware, whosoever you are in the Church, do not revile them that are not within; but pray ye rather, that they too may be within. For God is able again to graft them in. [Romans 11:23] Of the very Jews the Apostle said this, and it was done in their case. The Lord rose again, and many believed: they perceived not when they crucified, nevertheless afterwards they believed in Him, and there was forgiven them so great a transgression. The shedding of the Lord's blood was forgiven the manslayers, not to say, God-slayers: "for if they had known, the Lord of glory they never would have crucified." [1 Corinthians 2:8] Now to the manslayers has been forgiven the shedding of the blood of Him innocent: and that same blood which through madness they shed, through grace they have drunk....O fullness of Gentiles, say thou to God, "How to be feared are Your works!" and so rejoice thou as that you may fear, be not exalted above the branches cut off.”

“Say unto God,.... Or, "concerning God" (t), as some; or, "before God", as the Targum; say to him as follows, in psalms and hymns of praise: how terrible art thou in thy works! or "reverend" (u); to be feared and reverenced with a godly fear on account of them; such as the works of nature and providence, which are stupendous and marvellous, fearfully and wonderfully wrought; and especially those of grace and redemption, in which the goodness of Christ is manifest, and for which he is to be feared: unless rather his judgments upon his enemies are here meant; who, though he is a Lamb to his own people, is the Lion of the tribe of Judah to them, whom he will break in pieces as a potter's vessel it may be read, "how terrible", or "tremendous", is everyone of "thy works"; so Aben Ezra, and also Jarchi, who interprets the next clause, through the greatness of thy power, thus, "when thou showest to the world thy power, by the pestilence, or sword, or famine, or lightnings:'' shall thine enemies submit themselves unto thee? in a lying, flattering, and deceitful manner, as the word (w) here used signifies; See Gill on Psa 18:44; or, as the above interpreters, "they shall, through the greatness of fear, confess the lies and transgressions they have committed.'' It will be a forced, and not a free, confession and submission; Christ's enemies, whether they will or not, will be obliged to own that he is Lord, to the glory of God the Father, Phi 2:10. (t) "dicite de Deo", Campensis apud Gejerum; and some in Michaelis. (u) "reverendus", Junius & Tremellius. (w) "mentientur", V. L. Musculus, Montanus; "mendaciter se dedunt", Junius & Tremellius, Piscator, Amama.”

“Lie. Prove faithless to thee, (Psalm xvii. 46., &c.) notwithstanding the evidence of thy wonders, and their deceitful professions. Thus the Samaritans pretended they wished to assist the Jews to build the temple; yet soon after obtained an order from court to hinder it, 1 Esdras iv. 1., and viii. 36. (Calmet) — Pharao frequently promised to let the people go, but as often broke his word. (Worthington) — They had been moved with servile fear. (Menochius) — The sight of God’s judgments upon the world was enough to inspire terror. (Worthington)”
