John Gill's Exposition of the Whole Bible
Psalms 66:3
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;
Psalms 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, Philippians 2:10.
