Ezekiel 40:5

A wall — This was that outmost wall, that compassed the whole mount Sion, upon whose top the temple stood. The man's hand — Christ, hath, and keeps the reed in his own hand, as the only fit person to take the measures of all. A measuring reed — Or cane, for this measuring rod was of those canes growing in that country, long, and light, which architects made use of. Six cubits long — Each cubit consisting of eighteen inches in our common account. An hand breadth — Added to each six cubits. The breadth — The thickness of the walls, which were one reed, and one hand's breadth, or three yards, and three inches thick. Height — And the height equal, taking the measure from the floor on the inside of the wall.
