A person facing a sudden downfall often discovers that their previous success only temporarily silenced their enemies. When the tide turns, hidden resentment quickly erupts into a toxic environment of slander and open aggression [ביאור שטיינזלץ].
The primary approach among commentators explains that the experience of being surrounded by hatred means the victim is actively besieged by curses and insults [אבן עזרא, מאירי]. Another perspective views this in a more visual way, suggesting that the hateful words themselves act as a physical barrier enclosing him [אבן עזרא]. This hostility is not always expressed directly to his face. Instead, the slander circles him from the outside, spoken behind his back [אלשיך], stemming from a deep hostility that was long concealed in the hearts of his adversaries [מצודת דוד]. Historically, this reflects the vicious rumors spread about King David to King Saul, which ultimately provoked Saul to hunt David down and surround him in battle [רד״ק].
This conflict is entirely unprovoked and lacks any justification, as the victim never caused his attackers any harm [רד״ק, מצודת דוד]. The injustice is even more profound because he actually went out of his way to do good for them, showing them many acts of kindness [מאירי]. Despite his complete innocence, these enemies band together with a single, ruthless goal: to wage war against him and bring about his total destruction [אלשיך].
