Shared ground
Zechariah 12:4–6 portrays a decisive reversal “in that day”: God destabilizes the attackers’ military power while giving focused care to Judah. The text is explicit that enemy war capacity is disrupted (horses struck with terror/blindness; riders with madness) and that Judah’s leaders gain inner confidence tied to Jerusalem’s relationship to “Yahweh of Hosts.”
The passage also makes a strong claim about agency: the turning point is God’s action (“I will strike… I will open my eyes… I will make…”), not Judah’s natural advantage. Judah’s leaders act, but only after God’s intervention enables them.
Where interpretation differs
Some readers take the horses/riders language mainly as literal battlefield imagery; others hear it as a picture for military technology and power more generally (whatever form it takes). Either way, the effect is the same in the passage: the attackers lose coordinated strength.
There is also real uncertainty about how to locate “in that day.” Some read it as pointing to an event or pattern near Zechariah’s post-exile setting; others see it as a later, climactic horizon tied to the larger end-of-book hopes for Jerusalem (cf. Zechariah 12:1–9).
Finally, “they shall devour all the peoples round about” can be heard in a range from decisive military defeat to more sweeping destruction. The metaphors (firepot/torch) press toward thoroughness, but metaphor still leaves questions about the exact kind of outcome envisioned.
Why the disagreement exists
The passage uses dense prophetic imagery (horses, blindness, fire devouring) that can describe real warfare while also functioning as symbolic language. It also sits inside a larger section marked by repeated “in that day,” which can describe either a near decisive moment or a later comprehensive one.
What this passage clearly contributes
It presents God as the one who can unmake an invader’s advantage and stabilize a threatened community. It links Judah’s strength to Jerusalem’s people specifically because “Yahweh of Hosts [is] their God,” making the relationship between God, Jerusalem, and Judah central to the outcome. It also depicts God empowering Judah’s leaders to overcome surrounding enemies and concludes with a concrete result: Jerusalem continues inhabited “in their own place,” signaling security and continuity rather than erasure or exile.
