Complete vulnerability and humiliation occur when a person is stripped of their most personal defenses. The plunder carried out by enemies reaches an extreme point of degradation when they take not just general wealth, but the very clothes off a person's back. The primary approach among commentators is that this represents a total theft of every asset, going so far as to strip the garments from the victim's body while he is still alive, distributing the pieces among the looters [רש״י, רד״ק, המאירי, ביאור שטיינזלץ].
While this action may be seen as a repeated idea meant simply to strengthen the message of the theft [מצודת דוד], there is also a clear distinction between the types of clothing taken. A person's general attire consists of multiple pieces, which the enemies can easily divide among themselves. However, a singular, unique item—such as a royal robe—cannot be divided without destroying it. Consequently, the enemies must cast lots to decide who will claim the intact prize [מלבי״ם]. This meticulous handling of the clothing and the casting of lots highlight the high status of the victim, as it is the precious nature of royal garments that fuels the captors' greed [אבן עזרא]. Offering a unique scenario, another perspective suggests that the enemies covet and divide the victim's regular clothes, but the lots are cast over a royal garment they themselves brought. In this case, they are competing to see who wins the honor of presenting it to him [אלשיך].
Despite the overwhelming feeling of helplessness and public exposure, a vital point of hope remains. The enemies may strip away property and tear off a person's outer layers, but their power is strictly limited to clothing. They are entirely unable to touch the victim's body or cause physical harm, because God is close and ready to save him [מלבי״ם].
