The hostility of the wicked is not always a public display of force; often, it operates in the shadows through treacherous, calculated surprise attacks. Enemies of justice prepare a careful ambush, using their physical strength to step on and string their weapons [רש״י]. They carefully stabilize and aim their arrows on the bowstring [מצודת ציון, ביאור שטיינזלץ], intending to shoot from the cover of darkness [רד״ק, מצודת ציון, מאירי] to strike innocent people who are upright in their hearts [רד״ק, מאירי].
The primary approach among commentators is to view this military imagery as a metaphor for the destructive power of gossip and slander. The bow represents the human tongue, and the arrows are deceitful words of defamation spoken in secret [רש״י, מאירי]. Historically, this points to Doeg the Edomite and the informers who fueled the bitter conflict between David and King Saul. The innocent victims struck by these metaphorical arrows of false accusations were David himself and the priests of the city of Nob, who were tragically killed because of this slander [רש״י, מצודת דוד].
Another historical perspective links this ambush to the Assyrian king Sennacherib's siege of Jerusalem. In this scenario, the wicked are Shebna and his followers, who betrayed King Hezekiah. They used actual bows and arrows to shoot a letter of surrender out of a window into the enemy camp. Their goal was to break the resolve of the righteous leaders of that generation, King Hezekiah and the prophet Isaiah [תורה תמימה, רד״ק]. Moving beyond physical weapons and harmful words, the imagery also serves as a philosophical metaphor. The bow and arrow represent false foundational ideas that launch destructive conclusions, designed to damage the soul [אלשיך].
Regarding the final outcome of these dark ambushes, commentators offer differing perspectives. While some maintain that the wicked successfully carry out their schemes and strike the innocent [מלבי״ם], others emphasize a different reality. Because these attacks are launched in absolute darkness, the arrows ultimately miss their true target. The malicious plots fail completely, as the upright find shelter in God and are safely rescued [רד״ק, אלשיך].
