The pursuit of material wealth often carries an illusion of stability, but hard-earned assets can vanish in an instant. The primary approach among commentators is that relying on money is ultimately futile, as its very nature is to slip away quickly. The speed of this loss is intimately tied to the simple act of looking. Some explain that in the brief moment a person merely closes their eyes, their wealth can completely disappear [רש״י, מלבי״ם]. Others suggest that taking a quick glance at one's money is enough for it to be gone [מצודת ציון, מצודת דוד, ביאור שטיינזלץ]. Alternatively, this sudden disappearance occurs precisely at the moment a person's eyes light up with satisfaction while looking at their fortune [אבן עזרא].
When wealth is lost, it does not merely slip away quietly; it actively makes wings for itself. Rather than a person finding shelter under the protective wings of their riches, the wealth grows wings to escape. These wings symbolize the specific circumstances that lead to financial ruin, such as thieves or poor business decisions. At times, God will intentionally cloud a person's judgment, allowing the wealth itself to generate the reasons for its own departure [אלשיך]. This sudden loss is compared to an eagle flying into the sky. Just as an eagle carries its young to heights no other bird can reach, when wealth begins to slip away, it becomes completely untouchable, and there is no way to stop or save it. Furthermore, while accumulating wealth is a slow and gradual process, much like an eagle slowly gaining altitude, its loss happens all at once, resembling an eagle diving at tremendous speed toward its prey [אלשיך].
As the wealth flies upward to the heavens, it symbolizes money returning to God. He reclaims it from one individual and transfers it to another exactly as He sees fit [רלב״ג, אלשיך]. Beyond financial matters, this concept also serves as an allegory for the study of wisdom and divine teachings. In this light, understanding does not sustain itself; it requires immense diligence and persistence. Wisdom is compared to a live bird held tightly in a person's hand. If a person closes their eyes and becomes distracted from their studies for even a brief moment, their knowledge will instantly fly away and escape [מלבי״ם]. Additionally, this serves as a warning against acquiring wisdom from an unworthy teacher, or approaching study with a negative attitude and flawed perspective [אמרי דעת].
