Zechariah 12:4 - Matthew Poole's English Annotations on the Holy Bible

In that day: see Malachi 4:3. I will smite every horse: horses are of very great use in wars; they were the main strength of Antiochus Epiphanes, his best preparations. With astonishment; a dull, sottish fear and perplexity. And his rider with madness; an impotency of mind both in the understanding, which is folly and imprudence, and in the will and resolution, which is either cowardice or unconstancy, like madmen that neither know how to resolve or act. God will turn all their counsel into foolishness, their strength into weakness, their courage into fear, and so overturn them all. I will open mine eyes upon the house of Judah; a while I seemed as one that slept or winked at the proceedings of my church's enemies, yet now I will open mine eyes, and see all that is going forward against them, and I will watch over my people for good; against their enemies, to confound and destroy them and their enterprises: this eye of God open upon his people is his wise, powerful, gracious providence for them, Psalms 31:22 Jeremiah 24:6. I will smite every horse of the people with blindness; all their warriors in their projecting and consults shall be as full of improvidence, and have as little foresight, as a stark blind man hath of sight to see by.
