There is a profound contrast between the fleeting nature of wealth gained through deceit and the stable, enduring value of a fortune built on honesty and hard work. Drawing upon the imagery of a hunter, the primary approach suggests that a deceitful person will never truly enjoy the fruits of his labor. He will not even have the chance to roast and eat his ill-gotten catch [מצודת ציון, אמרי דעת]. Before he can benefit from it, his wealth will be taken from him, stolen by others, or his dishonesty will be discovered, causing people to refuse to do business with him [רש״י, רלב״ג, אבן עזרא, עמנואל הרומי].
Another perspective grounds this idea in a practical hunting technique, where hunters would slightly singe the wings of captured birds to prevent their escape. A deceitful person might avoid doing this, hoping to keep the birds looking pristine so he can more easily cheat potential buyers. In the end, however, the birds simply fly away, leaving him with nothing. This serves as a metaphor for a stingy person who refuses to give charity from his wealth, and as a result, loses his entire fortune [ביאור שטיינזלץ, מצודת דוד].
The imagery also evokes the idea of a window or lattice. Because his wealth is acquired through robbery, the deceiver is forced to hide his loot, unable to proudly display his catch in the open [מלבי״ם]. Furthermore, consumed by the desire to steal, he peers through the cracks, entirely blind to the tragic fate that awaits him [אמרי דעת]. Taking this concept into the realm of repentance, a person might mistakenly believe he can accumulate wealth through fraud and later use those funds for charity, hoping the merit of the good deed will burn away the sin of his deceit. However, the ill-gotten catch cannot erase the transgression, as a Commandment fulfilled through a sin offers no atonement [האלשיך].
In stark contrast stands the honest individual, whose character and reward share a dual essence: unwavering diligence and pure gold. On one level, this describes someone who is truthful, hardworking, and quick in his labor, earning his livelihood through sincere effort rather than fraud [רש״י, אבן עזרא, מלבי״ם, עמנואל הרומי]. On another level, it refers to fine, unblemished gold [רלב״ג, מצודת ציון, מצודת דוד, ביאור שטיינזלץ]. These two ideas naturally complement each other. The wealth accumulated by a diligent and honest worker is precious, enduring over time, and protected from misfortune. Ultimately, the most honorable and lasting wealth a person can possess—wealth that remains as pure and unspoiled as fine gold—is the direct result of a life lived with honesty, hard work, and a commitment to charity [מצודת דוד, עמנואל הרומי, ביאור שטיינזלץ, אמרי דעת].
