Urgency and immediate action are vital when a pressing task lies ahead, leaving no room for procrastination or neglect. A clear distinction exists between deep, steady sleep and a light, temporary slumber [מלבי״ם]. When facing a critical situation, both must be completely avoided. On a practical level, this applies directly to a person who has fallen into debt or finds himself in a difficult predicament. In such a state, he must work tirelessly and without rest. He should not allow himself to sleep until he has paid off what he owes and freed himself from the burden of his troubles [אבן עזרא, ביאור שטיינזלץ].
Beyond the specific issue of financial debt, the primary approach among commentators views this as a broader warning against the dangers of laziness. Tasks should never be put off with the excuse that they will be handled only when free time becomes available [אלשיך, מצודת דוד]. Instead, a person must act with intense drive and a sense of urgency. The ideal attitude is that of someone so passionate about completing his mission that he simply cannot close his eyes until his plans are fully realized [עמנואל הרומי].
On a spiritual and philosophical level, this urgency transforms into a call to awaken the mind and soul. A person must remain alert and vigilant, keeping the eye of the intellect wide open and refusing to let it fall asleep. This mental sharpness is what allows a person to control physical desires and escape the trap of being enslaved to the material world, much like a deer or a bird breaking free from a snare [אמרי דעת]. Through constant seeking and quickness in acquiring wisdom, a person is able to distance himself from evil and cling to God [רלב״ג].
