Letting time slip away in idleness sets the stage for an inevitable and quiet decline. Poverty and lack are personified as approaching figures, serving as a stark warning to anyone who allows life to pass by doing nothing. The descent into ruin often happens without any prior warning. The primary approach among commentators is that poverty arrives suddenly, much like a traveler or guest who shows up unannounced at an inn [אבן עזרא, מצודת דוד]. It can also be seen as advancing quickly and confidently, with the steady pace of someone accustomed to marching [רש"י, ביאור שטיינזלץ].
As the situation deteriorates, the next stage of ruin takes hold. The primary approach among commentators explains that this subsequent lack arrives swiftly and decisively, resembling an armed soldier with a shield rushing into battle, marching forward without anything to stop him [רש"י, אבן עזרא, מצודת דוד, ביאור שטיינזלץ]. However, this can also be understood as a gradual process. At first, poverty enters easily like a simple wanderer with no one standing in its way. By the time the lack worsens and the person finally tries to fight it off and chase it from their home, the destitution has already taken the form of an armored soldier, making it impossible to defeat [מלבי"ם]. Alternatively, it is the lazy person who is left entirely defenseless and exposed to punishment, much like a cavalryman in battle who has lost the shield that was supposed to protect him from enemy blows [אמרי דעת].
Beyond physical wealth, there is a deep spiritual allegory at play, warning against laziness in the study of Torah and the performance of good deeds [רש"י, אמרי דעת]. When a person finally wakes up from the slumber of worldly illusions and examines their actions, they suddenly discover their own spiritual poverty and inner emptiness [אלשיך]. Yet, this realization carries a profound comfort for those who choose to repent. When a person returns to God out of pure love, their intentional sins are transformed into merits. In such a state, their very flaws and past emptiness become their defenders, standing up to protect them like a shield-bearing soldier [אלשיך].
Finally, a Midrashic perspective offers a glimpse of ultimate hope. The language used to describe this approaching poverty also contains a hidden hint to leadership, pointing toward the Messiah who will one day march at the head of Israel and lead them forward [מנחת שי].
