The downfall of those who pursue evil is often brought about by the very weapons and plots they prepare against the righteous. God ensures that the wicked are repaid exactly according to their actions. The weapons and schemes they carefully craft to harm the poor and the upright ultimately turn against them, resulting in the exact opposite of their original intentions. The swords they draw end up piercing their own hearts [אבן עזרא, רד״ק, מצודת דוד]. In a similar manner, their bows are shattered, completely stopping them from firing their arrows and carrying out their wicked plans [רד״ק, מצודת דוד].
This destruction extends far beyond physical weaponry. The shattering of these tools of war also represents the crushing of the spiritual forces of impurity and the heavenly powers that support those who do evil. A clear historical example of this divine reversal is Nimrod's plot to harm Abraham. God intervened and turned the scheme upside down, causing the intended harm to fall upon Nimrod himself.
Understanding this pattern offers deep comfort. There is no reason to despair or feel sadness when witnessing the temporary success of wicked people. God clearly sees the day of their downfall and actively ensures that the evil they project into the world returns directly to them [אלשיך].
