Zechariah 14:9

And the Lord shall be King - When this universal diffusion of Divine knowledge shall take place. Wherever it goes, the laws of God shall be acknowledged; and, consequently, he shall be King over the whole earth. One Lord, and his name one - There shall be in those blessed days, only one religion, and one form of religion. There shall not be gods many, and lords many. All mankind shall be of one religion, the essence of which is, "Thou shalt love the Lord thy God with all thy heart, soul, mind, and strength; and thy Neighbor as thyself."

king over all . . . earth-- Isa 54:5 implies that this is to be the consequence of Israel being again recognized by God as His own people (Dan 2:44; Rev 11:15). one Lord . . . name one--Not that He is not so already, but He shall then be recognized by all unanimously as "One." Now there are "gods many and lords many." Then Jehovah alone shall be worshipped. The manifestation of the unity of the Godhead shall be simultaneous with that of the unity of the Church. Believers are one in spirit already, even as God is one (Eph 4:3-6). But externally there are sad divisions. Not until these disappear, shall God reveal fully His unity to the world (Joh 17:21, Joh 17:23). Then shall there be "a pure language, that all may call upon the name of the Lord with one consent" (Zep 3:9). The Son too shall at last give up His mediatorial kingdom to the Father, when the purposes for which it was established shall have been accomplished, "that God may be all in all" (Co1 15:24).

And the Lord shall be King over all the earth,.... This refers to the spiritual reign of Christ in the latter day; upon the success of the Gospel everywhere, there will be great conversions in all places; Gospel churches will be set up and ordinances administered everywhere; the earth will be filled with the knowledge of the Lord; his kingdom will be from sea to sea, from the eastern to the western one, and his dominion will reach to the ends of the earth; Popish nations, Mahometan kingdoms, Pagan ones, and all the kings of the earth, will become Christian, and submit to the sceptre of Christ's kingdom: in that day shall there be one Lord; there is but one Lord in right now, and there is but one in fact that is owned by real Christians; and there will be but one in the spiritual reign, among all that are called Christians; there will be but one Lord and Head to Jews and Gentiles, Hos 1:11 the pope of Rome will be no more owned as head of the church, nor any other: and his name, one; this refers not to any particular name by which Christ shall be called; but rather to that by which his people shall be called; all names of distinction being now laid aside, and only that of Christians retained; though it chiefly designs unity of doctrine, uniformity of worship, one and the same way of administering ordinances: it signifies that there will be one true, spiritual, uniform worship and religion; there will be no different sentiments and principles in religion; nor different practices and modes of worship; nor different sects; but all agreeing in the same faith and practice, under one Lord and King, Christ Jesus. So the Targum, "they shall serve before the Lord with one shoulder; for his name is firm in the world, and there is none besides it.'' This passage is referred by the…

Divers things were foretold, in the two foregoing chapters, which should come to pass "in that day;" this chapter speaks of a "day of the Lord that cometh," a day of his judgment, and ten times in the foregoing chapters, and seven times in this, it is repeated, "in that day;" but what that day is that is here meant is uncertain, and perhaps will be so (as the Jews speak) till Elias comes; whether it refer to the whole period of time from the prophet's days to the days of the Messiah, or to some particular events in that time, or to Christ's coming, and the setting up of his kingdom upon the ruins of the Jewish polity, we cannot determine, but divers passages here seem to look as far forward as gospel-times. Now the "day of the Lord" brings with it both judgment and mercy, mercy to his church, judgment to her enemies and persecutors. I. The gates of hell are here threatening the church (Zac 14:1, Zac 14:2) and yet not prevailing. II. The power of Heaven appears here for the church and against the enemies of it (Zac 14:3, Zac 14:5). III. The events concerning the church are here represented as mixed (Zac 14:6, Zac 14:7), but issuing well at last. IV. The spreading of the means of knowledge is here foretold, and the setting up of the gospel-kingdom in the world (Zac 14:8, Zac 14:9), which shall be the enlargement and establishment of another Jerusalem (Zac 14:10, Zac 14:11). V. Those shall be reckoned with that fought against Jerusalem (Zac 14:12-15) and those that neglect his worship there (Zac 14:17-19). VI. It is promised that there shall be great resort to the church, and great purity and piety in it (Zac 14:16, Zac 14:20, Zac 14:21).

14:9 the Lord will be king: Zechariah envisions the ultimate fulfillment of many psalms (see Pss 47–48, 93, 97-99). • there will be one Lord: This promise reaffirms Israel’s creed (Deut 6:4) and signals a final end of all idolatry.
