The approaching enemy army operates as a lethal, unstoppable force, perfectly equipped for total destruction. The soldiers carry quivers [רש״י, מצודת ציון] that act like open graves, a stark image illustrating their absolute lethality. Just as a grave is always ready to receive the dead, every single arrow pulled from these warriors' supplies finds its mark, delivering certain death without ever missing [רד״ק, מלבי״ם]. Furthermore, this arsenal of arrows appears completely endless, holding an unlimited capacity for destruction [ביאור שטיינזלץ].
Beyond their deadly precision from a distance, the soldiers themselves are fiercely powerful in close-quarters combat. They are highly trained warriors who fight with relentless intensity, ensuring there is absolutely no avenue of escape for their victims [רד״ק, ביאור שטיינזלץ].
Together, these elements create a terrifying and complete picture of war. The enemy first rains down inevitable death from afar, and as the battle shifts to hand-to-hand combat, the soldiers unleash their overwhelming physical strength, proving to be a force that cannot be withstood [מלבי״ם].
