The breadth of the gate from the roof of one little chamber or lodge to another, measuring from door to door, was five and twenty cubits, which were thus made up: 10 cubits of footway + 12 (2 x 6) cubits for the two guard-rooms + 3 (2 x say 1.
5) cubits for the thickness of the two side walls = 25 cubits in all. According to Ezekiel 40:42, the length of a hewn stone was one cubit and a half. The doors from which the measurements were taken must have been in the side walls at the back of the guard- looms.
