Yechezkel 42:4-6

Orthodox Jewish Bible

⁴ And before the leshakhot was a mahalach (walkway) ten cubits in width leading inward, a way of one cubit; and their doors toward the north.

⁵ Now the upper leshakhot were narrow; for the atikim took space from these, from the lower, and from the middlemost of the Binyan.

⁶ For they were in three stories, but had not ammudim like the ammudim of the khatzerot; therefore they were set back from the ground more than the lowest and the middlemost.
