12 And this shall be the plague with which the Lord will strike all the peoples that wage war against Jerusalem: their flesh will rot while they are still standing on their feet, their eyes will rot in their sockets, and their tongues will rot in their mouths. 13 And on that day a great panic from the Lord shall fall on them, so that each will seize the hand of another, and the hand of the one will be raised against the hand of the other. 14 Even Judah will fight at Jerusalem. And the wealth of all the surrounding nations shall be collected, gold, silver, and garments in great abundance. 15 And a plague like this plague shall fall on the horses, the mules, the camels, the donkeys, and whatever beasts may be in those camps.

Matthew Henry's Commentary on Zechariah 14:12-15

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.
