6 For they were in three stories, but had not pillars as the pillars of the courts: therefore the building was straitened more than the lowest and the middlemost from the ground.
7 And the wall that was without over against the chambers, toward the utter court on the forepart of the chambers, the length thereof was fifty cubits.
8 For the length of the chambers that were in the utter court was fifty cubits: and, lo, before the temple were an hundred cubits.
