Psalms 97:3-6

Verse 3

A fire goeth before him - Literally, this and the following verse may refer to the electric fluid, or to manifestations of the Divine displeasure, in which, by means of ethereal fire, God consumed his enemies. But fire is generally represented as an accompaniment of the appearances of the Supreme Being. He appeared on Mount Sinai in the midst of fire, thunder, and lightninys, Exo 19:16-18. Daniel, Dan 7:9, Dan 7:10, represents the Sovereign Judge as being on a throne which was a fiery flame, and the wheels of his chariot like burning fire; and a fiery streamer issuing from it, and coming forth from before him. St. Paul tells us (2Thes 1:8) that the Lord Jesus shall be revealed from heaven with his mighty angels, in faming fire; and St. Peter, (2Pet 3:7, 2Pet 3:10, 2Pet 3:11), that when the Lord shall come to judgment the heavens and the earth shall be destroyed by fire. the heavens shall pass away with a great noise, the elements melt with fervent heat, and the earth and its works be burnt up. Here then, will appear: - "Our God in grandeur, and our world on fire."

Burneth up his enemies round about - The fire is his pioneer which destroys all the hinderances in his way, and makes him a plain passage.
Verse 4

His lightnings enlightened the world - Though this be no more than a majestic description of the coming of the Lord, to confound his enemies and succor his followers, yet some spiritualize the passage, and say, the lightnings signify the apostles, who enlightened the world by their heavenly doctrine.

The earth saw, and trembled - The earth is represented as a sentient being. It saw the terrible majesty of God; and trembled through terror, fearing it should be destroyed on account of the wickedness of its inhabitants.
Verse 5

The hills melted like wax - The fire of God seized on and liquefied them, so that they no longer opposed his march; and the mountains before him became a plain.

The Lord of the whole earth - אדון כל הארץ adon col haarets, the Director, Stay, and Support of the whole earth. The universal Governor, whose jurisdiction is not confined to any one place; but who, having created all, governs all that he has made.
Verse 6

The heavens declare his righteousness - They also, in this poetic description, become intelligent beings, and proclaim the majesty and the mercy of the Most High. Metaphorically, they may be said to declare his glory. Their magnitude, number, revolutions, order, influence, and harmony, proclaim the wondrous skill, matchless wisdom, and unlimited power of the Sovereign of the universe. See the notes on Psa 19:1-14 (note).

And all the people see his glory - Whatsoever God has made proclaims his eternal power and Godhead; and who, from a contemplation of the work of his hands, can be ignorant of his being and providence?
