Divine justice often operates measure for measure, where the very weapons intended to harm innocent people become a deadly trap for their creators. The imagery centers on lethal instruments that the wicked carefully plan to use against others [אבן עזרא]. The primary approach among commentators is that this scene involves relentless pursuers hunting down their victims [רש״י, רד״ק, מצודת ציון, אבן עזרא]. However, an alternative understanding suggests the imagery describes the weapons themselves, portraying them as being forged in a burning fire, much like a freshly polished sword [אבן עזרא].
There are two main ways to understand how this justice is delivered. One perspective focuses on the self-destructive nature of evil. The wicked person labors to build his arsenal, but he is unknowingly preparing it for his own downfall. His ultimate punishment is that the very arrows and tools he crafted with his own hands to strike the righteous will reverse course, and he will ultimately be killed by his own creations [רד״ק, מצודת דוד, ביאור שטיינזלץ, אלשיך, מלבי״ם].
A second perspective shifts the focus to God as the active enforcer of justice. In this view, it is God who prepares the instruments of death specifically for the wicked. God readies His own divine arrows to strike down those who chase after the righteous, ensuring that every arrow acts directly and precisely against the pursuers [רש״י, מאירי].
