The object of breaking down the wall was to leave Jerusalem at the mercy of her rival; and it must have been among the conditions of the peace that the breach thus made should not be repaired.
Gates in Oriental cities are named from the places to which they lead. The gate of Ephraim must therefore have been a north gate: perhaps also known, later on, by the name of the “gate of Benjamin” Jeremiah 37:13; Zechariah 14:10. The corner gate was probably a gate at the northwest angle of the city, where the north wall approached the Valley of Hinnom. The entire breach was thus in the north wall, on the side where Jerusalem was naturally the weakest. Josephus says that Joash drove his chariot through the breach into the town, a practice not unusual with conquerors.
