4 On that day his feet will stand on the Mount of Olives, east of Jerusalem. And the Mount of Olives will split apart, making a wide valley running from east to west. Half the mountain will move toward the north and half toward the south. 5 You will flee through this valley, for it will reach across to Azal. Yes, you will flee as you did from the earthquake in the days of King Uzziah of Judah. Then the Lord my God will come, and all his holy ones with him. 6 On that day the sources of light will no longer shine, 7 yet there will be continuous day! Only the Lord knows how this could happen. There will be no normal day and night, for at evening time it will still be light.

8 On that day life-giving waters will flow out from Jerusalem, half toward the Dead Sea and half toward the Mediterranean, flowing continuously in both summer and winter. 9 And the Lord will be king over all the earth. On that day there will be one Lord -his name alone will be worshiped. 10 All the land from Geba, north of Judah, to Rimmon, south of Jerusalem, will become one vast plain. But Jerusalem will be raised up in its original place and will be inhabited all the way from the Benjamin Gate over to the site of the old gate, then to the Corner Gate, and from the Tower of Hananel to the king's winepresses. 11 And Jerusalem will be filled, safe at last, never again to be cursed and destroyed.

Matthew Henry's Commentary on Zechariah 14:4-11

Commentary on Zechariah 14:1-7

(Read Zechariah 14:1-7)

The Lord Jesus often stood upon the Mount of Olives when on earth. He ascended from thence to heaven, and then desolations and distresses came upon the Jewish nation. Such is the view taken of this figuratively; but many consider it as a notice of events yet unfulfilled, and that it relates to troubles of which we cannot now form a full idea. Every believer, being related to God as his God, may triumph in the expectation of Christ's coming in power, and speak of it with pleasure. During a long season, the state of the church would be deformed by sin; there would be a mixture of truth and error, of happiness and misery. Such is the experience of God's people, a mingled state of grace and corruption. But, when the season is at the worst, and most unpromising, the Lord will turn darkness into light; deliverance comes when God's people have done looking for it.

Commentary on Zechariah 14:8-15

(Read Zechariah 14:8-15)

Some consider that the progress of the gospel, beginning from Jerusalem, is referred to by the living waters flowing from that city. Neither shall the gospel and means of grace, nor the graces of the Spirit wrought in the hearts of believers by those means, ever fail, by reason either of the heat of persecution, or storms of temptation, or the blasts of any other affliction. Tremendous judgments appear to be foretold, to be sent upon those who should oppose the settlement of the Jews in their own land. How far they are to be understood literally, events alone can determine. The furious rage and malice which stir up men against each other, are faint shadows of the enmity which reigns among those who have perished in their sins. Even the inferior creatures often suffer for the sin of man, and in his plagues. Thus God will show his displeasure against sin.
