Jewish life in Jericho
A marking point in the boundary between the Tribe of Judah and the Tribe of Benjamin is the Bohan Ben Reuven Stone, between Beit Ha’Arava and the Arava. This point can be placed between Wadi Kelt and Dvir.
The place matches the border between the mountains and the valley and stands as a scarp east of the Hasmonian Palaces. It really looks like a finger sticking out, just like the Hebrew name of Reuven’s son - "Bohan". Even before the Children of Israel entered the Land, under the kingdom of Achad, the Hebrew name had apparently been given. It is therefore conceivable that when Leah called her son "Reuven", she did not invent the name, but used an already popular name and gave it a new meaning.
