O worship the Lord in the beauty of holiness,.... See Gill on Psa 29:2, in this and the three preceding verses there is a manifest allusion to the form of addresses made to kings in the eastern nations; who being arrayed, and seated in a majestic manner, with all the marks of royal honour and dignity about them, whom their subjects approach with ascriptions of glory to them; bringing presents in their hands, and bowing down to the ground before them, as the word (r) for "worship" signifies; expressing the utmost awe and reverence of them, as in the next clause: fear before him, all the earth; or, as the Targum, "all the inhabitants of the earth;'' it is the duty of all men to fear the Lord; but none can fear him aright without his grace, or an heart given them to fear him: this respects the latter day, when the Jews shall seek the Lord, and fear him and his goodness; when all nations shall fear and worship him; when, from the rising of the sun to the going down of the same, the name of the Lord shall be great and tremendous among the Gentiles; see Hos 3:5. (r) "incurvate vos", Pagninus, Montanus, Junius & Tremellius, Piscator; "prosternite vos", Tigurine version.
