The Lord reigneth - The same commencement of a psalm occurs in Psalms 97:1-12; Psalms 99:1-9. The same idea is often found in the Scriptures. 1 Chronicles 16:31; Psalms 47:8; Isaiah 52:7; Revelation 19:6. The thought seems abrupt here. It would appear as if the psalmist had been meditating on the dark things which occur in the world; the mysteries which abound; the things which seem irreconcilable with the idea that there is a just government over the world, and that suddenly the idea occurs, as a flash of lightning in a storm, that Yahweh reigns over all, and that all must be right. Amidst all these things God sits upon the throne; he orders all events; he sways his scepter over all; he orders all things according to his own will; he secures the accomplishment of his own purposes.

He is clothed with majesty - That is, he puts on, or wears this; he appears in this as a garb, or robe. The word rendered “majesty” means properly “loftiness,” and is applied to the swelling of the sea Psalms 89:9, or to a column of smoke, Isaiah 9:18. The idea here is, that God is exalted; and that he appears in such a manner as to indicate his proper dignity. See the notes at Isaiah 6:1.

The Lord is clothed with strength, wherewith he hath girded himself - There is an allusion here to the mode of dress among the Orientals - the custom of girding the loins when one labored, or walked, or ran. See the notes at Matthew 5:38-41.

The world also is stablished - Is firm; is on a solid foundation. It cannot be shaken or destroyed by natural convulsions, or by the power of man.

That it cannot be moved - Moved out of its place; overthrown; destroyed. This seems to have been spoken in view of some impending calamity, as if everything were to be swept away. The psalmist consoles himself with the thought that the world was firmly established; that no storm or tempest could be so violent as to remove it out of its place. The ground of consolation is the essential stability of what God has ordained.
