As the members of the Tribe of Dan prepare to embark on a long journey and leave their familiar homeland behind, they establish a crucial staging area. They set up camp in the vicinity of Kiriath-jearim, using this location to gather necessary provisions for the road ahead [מלבי״ם]. This serves as their final stop before departing the region entirely [ביאור שטיינזלץ].
Rather than entering the city itself, the travelers choose to settle just outside its borders [מצודת דוד, מלבי״ם]. The specific site where they pitch their tents becomes known as the Camp of Dan, a name referring exclusively to their exact camping location [מצודת דוד]. To pinpoint this spot, the geographical position is described as being behind the city. This indicates that the camp is located on the far side of Kiriath-jearim, facing away from their starting points of Zorah and Eshtaol [מצודת דוד].
