Yechezkel 42:5-7

Orthodox Jewish Bible

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.

⁷ And the wall that was outside over against the leshakhot, toward the khatzer hakhitzonah on the forepart of the leshakhot, the length thereof was fifty cubits.
