The voice of the Lord is powerful - Margin, as in Hebrew: "in power." That is, is mighty; or, has strength. Allusion may be made to what seems to be the effect of thunder in prostrating trees, or tearing off their limbs, or it may be merely to the loud sound of the thunder.
Is full of majesty - Margin, as in Hebrew, "in majesty." That is, it is grand, sublime, overpowering.

Is powerful - There is no agent in universal nature so powerful as the electric fluid. It destroys life, tears castles and towers to pieces, rends the strongest oaks, and cleaves the most solid rocks: universal animate nature is awed and terrified by it. To several of these effects the psalmist here refers; and for the illustration of the whole I must refer to the above notes on Job.
Full of majesty - No sound in nature is so tremendous and majestic as that of thunder; it is the most fit to represent the voice of God.

The voice of the Lord is powerful,.... Or "with power" (a); as thunder, in the effect of it, shows; and so is the Gospel, when it comes, not in word only, but is attended with the power of God to the conversion and salvation of souls; it is then quick and powerful, Hebrews 4:12; and the word of Christ personal, when here on earth, was with power, Luke 4:32;
the voice of the Lord is full of majesty; Christ, in his state of humiliation, spake and taught as one having authority; and now, in the ministration of his Gospel by his servants, he goes forth with glory and majesty, Psalm 45:3.
(a) "in potentia", Pagninus, Montanus; "cum potentia", Cocceius, Michaelis; "with able power", Ainsworth.
