The military campaign through the southern region of Canaan moves swiftly from one city to the next, with the destruction of Eglon directly mirroring the earlier fall of Lachish. The account of Eglon's defeat closely parallels the previous battle, sharing a notable omission in the details of the conquest. In the records of both victories, there is no mention of capturing or executing the ruling monarch.
This absence of the kings is not an oversight in the historical record. The king of Eglon, much like the king of Lachish, had already met his end earlier in the campaign at the hands of Joshua [ביאור שטיינזלץ]. With the leadership of these cities previously eliminated, the narrative naturally leaves them out, focusing entirely on the capture and destruction of the cities themselves.
