A sudden report of an independent altar built on the eastern side of the Jordan River sends shockwaves through the western tribes of Israel, sparking immediate tension. Normally, spreading negative reports about others is strictly forbidden, raising a question about how this troubling information was allowed to circulate so widely and ultimately gather the entire nation together. One perspective suggests that the initial group who discovered the altar received explicit permission and instructions from the builders themselves to share the news, indicating that the construction was not a secretive act done in the shadows. Another possibility is that the initial report came from legally valid witnesses. Because the testimony met strict legal standards, it was entirely appropriate to transmit the information to the broader public [אלשיך].
The deep anxiety among the Israelites was rooted in the specific nature of the structure. The reports indicated that this was not just a generic, random monument. Instead, the listeners understood that the eastern tribes had constructed an exact replica of the central, famous altar located at the Tabernacle in Shiloh [מלבי״ם].
The placement of this new altar, situated at the very edges and slopes of the land, added to the growing alarm [ביאור שטיינזלץ]. Beyond its mere geographic location, the positioning was perceived as a direct and calculated threat. The Israelites suspected that the structure was deliberately built to face the western land of Canaan. They feared the underlying goal was to draw the attention of the western residents, swaying their hearts to abandon the established spiritual center in Shiloh and begin worshipping at this new, rival altar [מלבי״ם].
