² At the front of the length [is] a hundred cubits [at] the north opening, and the breadth fifty cubits.

³ Over-against the twenty [cubits] that are to the inner court, and over-against the pavement that [is] to the outer court, [is] gallery over-against gallery, in the three [storeys].

⁴ And at the front of the chambers [is] a walk of ten cubits in breadth unto the inner part, a way of one cubit, and their openings [are] at the north.
