⁵ And the upper chambers [are] short, for the galleries contain more than these, than the lower, and than the middle one, of the building;

⁶ for they [are] threefold, and they have no pillars as the pillars of the court, therefore it hath been kept back -- more than the lower and than the middle one -- from the ground.

⁷ As to the wall that [is] at the outside, over-against the chambers, the way of the outer-court at the front of the chambers, its length [is] fifty cubits;
