(1) The Lord reigneth.--See Note, Psalm 93:1.

Tremble.--LXX. and Vulg., "be angry." The optative in this and the following clause is after the LXX.; but the Hebrew is in the ordinary present, the peoples tremble, the earth staggers.

He sitteth.--In original a participle.

Between the cherubims . . .--See Notes on Psalm 80:1.

Verse 1. - The Lord reigneth (see the comment on Psalm 93:1). Let the people tremble; literally, the peoples; i.e. all the nations upon earth. He sitteth between the cherubim; rather, he hath his seat upon the cherubim (comp. Psalm 80:2). The imagery is taken from the internal economy of the Jewish temple, where the Shechinah was enthroned above the cherubic forms that overshadowed and guarded the ark. Let the earth be moved; or, quake (comp. Psalm 114:7).

99:1-5 God governs the world by his providence, governs the church by his grace, and both by his Son. The inhabitants of the earth have cause to tremble, but the Redeemer still waits to be gracious. Let all who hear, take warning, and seek his mercy. The more we humble ourselves before God, the more we exalt him; and let us be thus reverent, for he is holy.The Lord reigneth,.... The King Messiah, he is made and declared Lord and Christ; he has reigned, does reign, and ever will; see Psalm 93:1,

let the people tremble: with awe of his majesty, and reverence of his word and ordinances; rejoicing before him with trembling, as his own people and subjects do, Psalm 2:11, and so it agrees with Psalm 97:1, or it may be understood of the people that are enemies to Christ, who would not have him to reign, though he shall whether they will or not; and who will sooner or later tremble for fear of him, and his righteous judgment. Jarchi refers this to the war of Gog and Magog. The Septuagint, Vulgate Latin, and Arabic versions, render it, "let the people be angry"; or it may be rendered, "they are angry"; or "therefore they are angry"; because he reigns; so the people, both Jews and Gentiles, were angry and raged, when his kingdom was first visibly set up among them, Psalm 2:1, and so the nations will when he takes to himself his great power, and reigns, Revelation 11:18,

he sitteth between the cherubim; "upon" or "above", as the Septuagint, Vulgate Latin, and all the Oriental versions; alluding to the seat of the Shechinah, or divine Majesty, in the holy of holies; and respects either the exalted glory of Christ among the angels, and above them at the right hand of God, where they are subject to him, stand about him, ready to do his will; or rather his presence with his ministers of the word, who are the instruments of spreading his Gospel, and enlarging his kingdom and interest in the world; See Gill on Psalm 80:1.

let the earth be moved: not that itself out of its place, but the inhabitants of it; and these either with a sense of sin and duty, and become subject to Christ their King; or with wrath and indignation at him, or through fear of him, as before; Kimchi says, at the fall of Gog and Magog; it may be particularly understood of the land of Judea, and of the commotion in it, especially in Jerusalem, when the tidings were brought of the birth of the King Messiah, Matthew 2:1, or of the shaking and moving both of the civil and ecclesiastical state of the nation, and of the ruin of it; see Hebrews 12:26.
