נחמיה, פרק ו׳, פסוק י״ז

Even in the wake of great triumph, internal betrayal can threaten a nation's stability. Despite the successful reconstruction of Jerusalem's wall and the fear it struck into surrounding nations, Nehemiah found himself facing a hidden danger from within his own camp. The local leadership, consisting of the nobles and officials of Judah, was secretly corresponding with his primary opponent, Tobiah, exchanging letters back and forth [רש״י, ביאור שטיינזלץ].

The timing of this secret communication highlights the depth of the subversion. Some understand that these letters were exchanged while the wall was still being built, creating a constant obstacle to the work [רלב״ג]. Others point out that these connections persisted even after the construction was finished. Even though the officials clearly saw that the success of the project was an act of God, they continued to maintain a relationship of deep affection with Tobiah [מצודת דוד, מלבי״ם].

The motivation behind this ongoing relationship with an enemy stemmed from a complex social and political landscape. Tobiah was, in fact, an Israelite, albeit a wicked one [רש״י]. At that time, the division between the Jews and the Samaritans was not yet absolute. Because the Samaritans presented themselves as fellow Jews seeking to participate in the rebuilding effort, many people in Judah believed that the conflict with Tobiah was merely an internal political disagreement within a single nation [ביאור שטיינזלץ]. Furthermore, Tobiah had secured strong political alliances by marrying into the families of prominent officials, convincing many of them that he was a genuinely good and honest man [מלבי״ם].

Lacking the courage to confront Nehemiah openly, these officials chose to operate behind his back [ביאור שטיינזלץ]. Through their extensive network of letters, they effectively acted as spies. They leaked Nehemiah's confidential plans to Tobiah, which in turn provided Tobiah with the information he needed to send targeted, threatening messages meant to terrorize Nehemiah. This grim reality clarifies why Nehemiah was forced to appoint guards over Jerusalem and maintain a state of high security long after the physical wall was completed. The hidden threat coming from the Israelites themselves proved to be just as dangerous as the visible threat posed by the surrounding nations [מלבי״ם].
