Ezekiel 42:3-5

Young's Literal Translation

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.

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;
