דניאל, פרק ב׳, פסוק מ׳

The vision of the great statue reaches its dramatic peak with the rise of a fourth and final kingdom, symbolized by iron. The primary approach among commentators is that this fierce empire represents Rome [מלבי״ם, מצודת דוד]. Unlike the transitions between previous empires, the rise of this new power is not described as coming strictly after the one before it. Rome did not replace the Greek empire overnight. Instead, the two superpowers coexisted for a period, resting right next to each other in history, just as the copper thighs and iron legs of the statue are physically connected [מלבי״ם, מצודת דוד].

This final kingdom is defined by an unprecedented, aggressive force meant to conquer and shatter all the empires that preceded it. Its absolute might acts like a heavy hammer that crushes, flattens, and mashes everything in its path [רש״י, מצודת ציון, ביאור שטיינזלץ]. It is destined to subdue and break down all the different materials that made up the statue, leaving no remnant of the earlier kingdoms untouched [רש״י, יוסף אבן יחיא, ביאור שטיינזלץ]. The empire employs two distinct methods of domination. On one hand, it crushes and weakens certain nations, deliberately keeping them alive so they can be ruled and subjugated. On the other hand, it completely shatters and wipes out other nations until absolutely no trace of them remains [מלבי״ם]. This devastating force will strike the lingering remnants of Babylon and Media, and will even extend to the kingdom of Ishmael that will rise in the future [מצודת דוד].

One might wonder why iron is highlighted solely for its destructive power rather than its ability to build strong, defensive walls and fortresses. The answer lies in the structure of the empire itself. The legs of pure iron represent only the military arm of the kingdom—its generals, warriors, and fighters. While the outer provinces and ordinary citizens are represented later in the vision by the fragile feet mixed with clay, the military force is made of pure, unyielding iron. It contains no weaknesses, and its single, focused purpose is to trample and crush the enemy [אלשיך].
