The western boundary of the future city spans a fixed, expansive distance. Along this entire stretch, which measures exactly four thousand five hundred units across, a total of three gates will be constructed [מצודת דוד]. Each of these entrances is dedicated to a specific tribe of Israel, with the western wall featuring gates named for Gad, Asher, and Naphtali.
While the dimensions and the number of gates are clearly established, the reasoning behind this specific arrangement remains a mystery. It is unknown why these particular three tribes were selected for the western boundary rather than another direction. Additionally, the exact order in which their gates will be positioned along the wall is left unexplained [ביאור שטיינזלץ].
