Psalms 96:9

“O worship the Lord in the beauty of holiness, etc.] (See Gill on “<192902>Psalm 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 f1371 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…”

“O worship the Lord in the beauty of holiness - This verse is literally taken from 1 Chronicles 16:29-30. The margin here is, “in the glorious sanctuary.” The Septuagint, ἐν αὐλῇ ἁγίᾳ en aulē hagia - “in his holy court.” So the Latin Vulgate. On the meanings of the expression, see the notes at Psalms 29:2. Fear before him, all the earth - All lands; all people. The word rendered “fear” means properly to writhe, to twist, to be in pain; and then, to tremble, to quake, to be afraid. The word “tremble” would perhaps best express the idea here. It is that solemn awe produced by the sense of the divine presence and majesty which causes trembling. It denotes profound reverence for God.…”

“Beauty - Cloathed with all the gifts and graces, which are necessary in God's worship. Psalms 96:10”

“96:9 Worshipers should tremble in awe (96:4; see 18:7-15; 97:4) at the splendor of the Lord’s majesty and holiness (Heb 12:25).”
