E il confine saliva a Debir dalla valle di Achor, e così verso nord, guardando verso Gilgal, che è finito contro la salita di Adummim, che si trova sul lato sud del ruscello; e il confine passò lungo le acque di En-Shemesh, e le uscite di esso furono ad En-Rogel.
Rashi on Joshua

Rashi on Joshua
And it turned northward to Gilgol. When it reached Gilgol, the boundary widens, and the borderline extends northward to Gilgol which is opposite Maalei-adumim, whose elevation [Maalei] is south of the Valley. The valley therefore is outside the borderline and is not within the boundary of Yehudah.
Rashi on Joshua
