The destructive power of slander and deceit goes far beyond mere sound. Harmful words act as deadly weapons and hidden fires that strike with force from a distance, leaving behind lasting and unseen damage. This reality is especially painful when living among hostile nations who spread false accusations [אבן עזרא].
The primary approach among commentators compares harmful speech to two distinct and dangerous elements. First, it is likened to the sharp, pointed arrows of a strong warrior [מצודת ציון]. Just as an arrow can strike and kill someone standing far away, slander harms victims from a great distance [רש״י, מצודת דוד, מלבי״ם]. Shot with immense force, a warrior's arrow is designed to penetrate deeply [רד״ק]. In the same way, a person who speaks evil carefully selects harsh words, sharpening them with smooth delivery so they strike swiftly, often before the victim even realizes they have been attacked [אלשיך, מאירי]. The words themselves are sometimes viewed as arrows that heat up in mid-flight until they become burning embers [אבן עזרא].
The second element compares harmful speech to coals made from broom tree wood [מאירי, מצודת דוד]. The unique nature of these specific coals is that they appear cold and completely extinguished on the outside, yet they continue to burn intensely on the inside for a very long time [רש״י, רד״ק, מצודת דוד, מאירי]. This perfectly mirrors a deceitful person who presents a friendly face to the world while hiding evil intentions. The victim drops their guard, only to be burned when the hidden malice is finally revealed [רד״ק, מצודת דוד, מאירי]. Furthermore, these coals symbolize the lingering emotional damage caused by slander. The pain does not pass immediately; it continues to burn and consume the listener's soul long after the conversation ends [אלשיך]. A related perspective suggests that the arrows represent lies that kill from afar, while the coals represent the quiet deceit that burns a person from up close [מלבי״ם].
While the primary approach views these images as a description of the sin itself, an alternative perspective interprets them as the ultimate punishment waiting for the liar. According to this line of thought, a person's lies eventually turn back on them, bringing continuous suffering [ביאור שטיינזלץ]. This punishment arrives from two directions. God acts as the mighty warrior, striking the slanderer with arrows from above, while the broom tree coals represent the fires of hell burning and punishing the deceitful person from below [רש״י, תורה תמימה].
