4 And in that day his feet will be on the Mount of Olives, which is opposite Jerusalem on the east, and the Mount of Olives will be parted in the middle to the east and to the west, forming a very great valley; and half the mountain will be moved to the north and half of it to the south. 5 And the valley will be stopped ... and you will go in flight as you went in flight from the earth-shock in the days of Uzziah, king of Judah: and the Lord my God will come, and all his holy ones with him. 6 And in that day there will be no heat or cold or ice; 7 And it will be unbroken day, such as the Lord has knowledge of, without change of day and night, and even at nightfall it will be light.

8 And on that day living waters will go out from Jerusalem; half of them flowing to the sea on the east and half to the sea on the west: in summer and in winter it will be so. 9 And the Lord will be King over all the earth: in that day there will be one Lord and his name one. 10 And all the land will become like the Arabah, from Geba to Rimmon south of Jerusalem; and she will be lifted up and be living in her place; from the doorway of Benjamin to the place of the first doorway, to the doorway of the angle, and from the tower of Hananel to the king's wine-crushing places, men will be living in her. 11 And there will be no more curse; but Jerusalem will be living without fear of danger.

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.
