Following days of glory, the Israelites once resembled a beautifully tended and carefully guarded vineyard. Yet, a painful contrast emerges as the nation is left completely exposed and vulnerable. A deep sense of wonder arises over why this sudden shift occurred specifically at this moment [רש״י, מאירי, ביאור שטיינזלץ]. A direct complaint is leveled toward God, asking why He seemingly transformed into an enemy, entirely removing His shelter and protection from His people [רד״ק, מצודת דוד].
The destruction of the vineyard's physical walls represents the shattering of the nation's defensive barriers [מצודת ציון, ביאור שטיינזלץ]. Consequently, God left His vineyard completely abandoned. Now, anyone traveling past can freely pluck the fruit, looting and plundering without consequence [מצודת דוד, אלשיך].
This breach in the walls is understood not merely as a passive failure of defenses, but as an active divine intervention. The kings of the earth and the enemies of the Israelites never would have believed they possessed the power to breach the gates of Jerusalem. Therefore, God Himself had to break down the walls, signaling to the world that the vineyard was now unguarded and abandoned by its Owner. Only after this divine declaration did the enemies dare to enter and ruin the city [אלשיך]. Furthermore, the broken fences provide a convenient excuse for the looters. Because the barriers are gone and the vineyard spills out onto the public path, those who take the fruit argue that they are not stealing. They claim that anything found on an open road is ownerless property [חומת אנך].
Ultimately, this devastation unfolds in a gradual process. In the initial phase, the walls are breached, and casual travelers simply help themselves to the exposed fruit. However, this vulnerability paves the way for a much harsher second phase. Eventually, the true destroyers of the land, Nebuchadnezzar and his officers, arrive to completely annihilate the vine [מלבי״ם].
