איוב, פרק ל״ט, פסוק כ״א

The war horse is a creature of explosive power, radiating self-confidence and an intense readiness for the chaos of battle. As it anticipates the coming clash, the horse interacts with the valley terrain in a way that captures this restless energy. The primary approach among commentators understands this as a physical action, where the horse strikes the ground forcefully out of sheer excitement. Eager for the fight, it beats the earth until it carves out holes in the valley floor [רלב״ג, מלבי״ם, אבן עזרא, ביאור שטיינזלץ]. The sheer force of the animal's hooves is what tears up the soil [רמב״ן].

However, this activity in the valley can also be understood as a mission of scouting. In this view, the riders gallop swiftly to spy and search the landscape, scanning the terrain because a valley is a prime location for enemy forces to set ambushes [רש״י, מצודת דוד, מצודת ציון]. A third, unique perspective shifts the focus entirely to the enemy. Rather than the horse or rider digging, the enemy forces are the ones digging trenches and setting traps in the valley. When the horse hears these distant sounds of preparation, it is instantly awakened and provoked to fight [אלשיך].

This fierce readiness reflects the nature of the horse species as a whole, with each individual animal displaying the exact same drive and anticipation [מלבי״ם, רמב״ן]. Fueled by this alert state, the horse rejoices in its immense physical strength. It trusts completely in its ability to withstand the clash and eagerly awaits its role in the fight [מצודת דוד, מלבי״ם, אבן עזרא]. Driven by this deep confidence and joy, the horse does not pull back. Instead, it charges forward with bold willingness, running directly toward the drawn weapons of the enemy forces [רש״י, רלב״ג, מצודת ציון].
