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, ( Psalms 2:11 ) , and so it agrees with ( Psalms 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, ( Psalms 2:1 Psalms 2:2 ) , 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 Psalms 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 Matthew 2:2 ) , 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 Hebrews 12:27 ) ( 1 Thessalonians 2:16 ) .
