The fall of Jerusalem was an event so dramatic that it completely shattered the political and military assumptions of the ancient world. Across the entire inhabited earth, kings and leaders viewed the city's strength and spiritual standing as absolute, considering its capture an impossible scenario [אבן עזרא, ביאור שטיינזלץ]. The disbelief among the nations stemmed from the fact that the capital was heavily fortified and simply could not be penetrated by conventional means [ביאור שטיינזלץ, צאינה וראינה].
Indeed, the Babylonian siege led by Nebuzaradan dragged on for three and a half years without success. The commander eventually grew desperate and prepared to abandon the campaign and return to his land. The breach only occurred through direct intervention from God. God inspired Nebuzaradan to measure the city wall, and each day, the wall miraculously sank deeper into the ground until it was completely swallowed by the earth, allowing the enemy forces to walk right in [תורה תמימה, אלשיך].
The nations of the world understood that the city possessed a dual layer of protection, consisting of both a physical and a spiritual gateway. Earthly Jerusalem was perfectly aligned with a heavenly counterpart, and world leaders firmly believed no human force could breach such a profoundly holy place. However, because of the severe sins of the people, the divine presence and upper holiness departed. The enemy was then able to enter through a purely physical gateway that had been stripped of its spiritual defense [אלשיך].
Because the destruction clearly defied the laws of nature, it became obvious to everyone that God Himself had ignited the fire and brought the enemy to their doorstep [פלגי מים, אלשיך]. Yet, the kings of the earth were surprised by His chosen method. They assumed that if God wished to punish His people, He would strike them with a plague within their own land. Instead, God deliberately chose to bring a foreign army and send the people into exile. This specific approach was an act of mercy, designed to allow a few righteous individuals the chance to escape and survive [אלון בכות].
The primary cause of this unimaginable disaster was the deep moral corruption of the leadership. False prophets and idolatrous priests actively shed the blood of true prophets, such as Zechariah, as well as righteous individuals and priests who tried to warn the people and correct their behavior. Under normal circumstances, the death of righteous people can bring atonement for an entire generation, provided the public genuinely mourns their loss. However, because the leadership in Jerusalem cruelly murdered these righteous figures, there was no sorrow or regret over their deaths. Without mourning, there could be no atonement, making the harsh reality of exile absolutely inevitable [לחם דמעה, אלשיך, אלון בכות].
