12 And this will be the disease which the Lord will send on all the peoples which have been warring against Jerusalem: their flesh will be wasted away while they are on their feet, their eyes will be wasted in their heads and their tongues in their mouths. 13 And it will be on that day that a great fear will be sent among them from the Lord; and everyone will take his neighbour's hand, and every man's hand will be lifted against his neighbour's. 14 And even Judah will be fighting against Jerusalem; and the wealth of all the nations round about will be massed together, a great store of gold and silver and clothing. 15 And the horses and the transport beasts, the camels and the asses and all the beasts in those tents will be attacked by the same disease.
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.
