The long journey through the wilderness brings the Israelites to a clear, recognizable geographic milestone. They establish their camp close to the banks of the Jordan River, positioned directly across from the city of Jericho [ביאור שטיינזלץ].
This leg of their travels involves moving from the mountains of Abarim down into the flat plains of Moab. This movement is the exact same stage of the journey recorded earlier in the Torah portion of Chukat, which details the route passing from Mattanah to Nahaliel [חזקוני].
