He ruleth by his power forever,.... Christ is the Ruler in Israel, King over his holy hill of Zion; who must reign till all enemies are put under his feet. He rules in the kingdom of nature and providence by his power, and does whatsoever he pleases; nor can any stay his hand. He rules in the kingdom of grace, in the hearts of his people, by his efficacious grace; which makes them willing, in the day of his power, to be subject to him; and in the latter day he will take to himself his great power and reign, when he will be King for ever. His kingdom is an everlasting kingdom, it shall never be subverted nor usurped; nor will he in it be succeeded by another; he will reign to the end of the world, throughout the thousand years, with his saints on earth, and then with them in heaven for evermore. The Targum renders it, "over the world;'' over the whole world; for Christ will be King over all the earth in the latter day, Zac 14:9; his eyes behold the nations; the antichristian states. He sees all the idolatry and wickedness committed in them; and his eyes will be as flames of fire to destroy them, when the time is come. The allusion is to God's looking through the pillar of fire and cloud upon the Egyptians in the Red sea, and troubling them, Exo 14:24; let not the rebellious exalt themselves. That are rebels against Christ, would not have him to reign over them; antichrist, who exalts himself above all that is called God, and all his followers. Or, "they shall not exalt themselves" (a): or, as the Targum, "they shall not be exalted in themselves for ever;'' see Rev 18:7. Selah; on this word; see Gill on Psa 3:2. (a) "haudquaquam sese exultabunt", Tigurine version, Musculus, & Gejerus.
