Zechariah 14:3-9,16 Prophecy of Judgment Day

Then shall the Lord go forth, and fight against those nations, as when he fought in the day of battle.  ⁴ And his feet shall stand in that day upon the mount of Olives, which is before Jerusalem on the east, and the mount of Olives shall cleave in the midst thereof toward the east and toward the west, and there shall be a very great valley; and half of the mountain shall remove toward the north, and half of it toward the south. ...And the LORD my God shall come, and all the saints with thee. And it shall come to pass in that day, that the light shall not be clear, nor dark ...at evening time it shall be light... And the LORD shall be king over all the earth... And it shall come to pass, that every one that is left of all the nations which come against Jerusalem shall ever go up from year to year to worship the King, the LORD of hosts.

...[23] In Zechariah: Jehovah shall go forth and fight against the nations; His feet shall stand in that day upon the Mount of Olives, before the faces of Jerusalem from the east; and the Mount of Olives shall be cloven asunder, a part thereof toward the east and toward the sea with a great valley, and a part of the mountain shall withdraw toward the north, and a part of it toward the south. Then shall ye flee through the valley of My mountains; and the valley of the mountains shall reach towards Azal (Zech. 14:3-5). This is said of the Last Judgment, which was accomplished by the Lord when He was in the world; for when the Lord was in the world He reduced all things to order in the heavens and in the hells, therefore He then wrought a judgment upon the evil and upon the good. This judgment is what is meant in the word of the Old Testament by "the day of indignation," "of anger," "of wrath," "of the vengeance of Jehovah," and by "the year of retributions" (on this judgment see the small work on The Last Judgment, n. 46). That the Lord's coming and the judgment that then took place are treated of in this chapter, is evident from these words in it: Then Jehovah my God shall come, all the holy ones with Thee. And there shall be in that day no light, brightness, nor flashing; and it shall be one day that shall be known to Jehovah, not day nor night; for about the time of evening there shall be light (Zech. 14:5-7). "The time of evening" means the last time of the church, when judgment takes place; then it is "evening" to the evil, but "light" to the good. As soon as these things are known, it becomes plain, through the spiritual sense, what the particulars here signify, namely, "Jehovah shall go forth and fight against the nations" signifies the Last Judgment upon the evil, "to go forth and fight" means to execute judgment, and "nations" the evil; "His feet shall stand upon the Mount of Olives, before the faces of Jerusalem from the east" signifies that this is effected from the Divine love by means of Divine truths proceeding from His Divine good; "the Mount of Olives" signifying, in reference to the Lord, the Divine love, "Jerusalem," the church in respect to truths, and therefore the Divine truths of the church, and "the east" the Divine good; "the Mount of Olives shall be cloven asunder, a part thereof toward the east and toward the sea, with a great valley" signifies the separation of those who are in good from those who are in evil; for "the Mount of Olives," as was said, means the Divine love; "the east" means where those are who are in Divine good, and "the sea" where those are who are in evil, for in the western quarter of the spiritual world is a sea which separates; "a part of the mountain shall withdraw toward the north, and part of it toward the south" signifies the separation of those who are in the falsities of evil from those who are in the truths of good; "the north" meaning where those are who are in the falsities of evil, since they are in darkness, and "the south" where those are who are in the truths of good, since they are in light; "then shall ye flee through the valley of my mountains" signifies that then those who are in truths from good shall be rescued, "to flee" signifying to be rescued, "the valley of the mountains" signifying where those are who are in the knowledges of truth, and thus in truths from good, for those who are in the knowledges of truth dwell in valleys, and those who are in good upon the mountains; "and the valley of the mountains shall reach even unto Azal" signifies separation from the falsities of evil, "Azal" signifying separation and liberation. [24] Because "the Mount of Olives," which was before Jerusalem eastward, signified the Divine love, and "Jerusalem from the east" Divine truth proceeding from Divine good, as was said above, the Lord was accustomed to stay on that mount, as is evident in Luke: Jesus during the days was teaching in the temple; but at night He went out and lodged in the mount that is called the Mount of Olives (Luke 21:37; 22:39; John 8:1). It was here, too, that He spoke with His disciples about His coming and the consummation of the age, that is, about the Last Judgment (Matt. 24:3 seq.; Mark 13:3 seq.). It was from here, also, that He went to Jerusalem and suffered (Matt. 21:1; 26:30; Mark 11:1; 14:26; Luke 19:29, 37; 21:37; 22:39); signifying thereby that He did all things from the Divine love, for "the Mount of Olives" signified that love; for whatever the Lord did in the world was representative, and whatever He spoke was significative...
