The overwhelming power, speed, and cruelty of the Chaldean army are vividly captured through the imagery of wild predators. This comparison highlights the physical traits of the warriors and their horses, as well as the sheer size of their military force. Their war horses possess an extraordinary speed that outpaces even leopards, animals well known for their swiftness [מצודת דוד, מצודת ציון, שטיינזלץ]. Beyond speed, a distinct sharpness and fierce energy define this force [רד״ק, מצודת ציון, שטיינזלץ]. There is a difference of opinion regarding the source of this fierce nature. Some suggest that the horses themselves are so wild and aggressive that even their own riders fear them [מלבי״ם]. Alternatively, the sharpness and quickness to strike apply directly to the Chaldean warriors themselves [מצודת דוד, אברבנאל].
This intense ferocity is compared to that of wolves. The primary approach among commentators is that this refers to wolves emerging to hunt at the beginning of the evening, driven by intense hunger and craving after fasting throughout the entire day. A different perspective suggests that the comparison is to wilderness wolves, specifically wild and exceptionally dangerous beasts that roam the forests and plains [מלבי״ם].
As the army advances, the cavalry forces present a terrifying sight. Most commentators explain that the riders constantly multiply; their numbers grow day by day, and they do not fall in battle [רש״י, רד״ק, מצודת דוד, מצודת ציון, אברבנאל]. This constant increase in numbers is driven by their robust health and physical strength [מלבי״ם]. On the other hand, a different interpretation suggests that rather than multiplying in number, the cavalry forces spread out widely across the land as they advance [אבן עזרא, שטיינזלץ].
Even though these forces travel from a great distance, the long journey does not leave them fatigued [מצודת דוד, אברבנאל]. Instead, they move with the sudden, rushing speed of an eagle. Because an eagle flies higher than all other birds, it can spot its prey from far away and dive down with sudden, blinding speed [רד״ק, שטיינזלץ]. In the exact same way, the Chaldean army flies toward its target without stopping to rest. They arrive fully prepared to fight, conquer, and plunder their enemies the moment they appear [מלבי״ם].
