Ezekiel 42:4-6

Complete Jewish Bible

⁴ In front of the [block of] rooms was a walkway seventeen-and-a-half feet wide and a path twenty-one inches [wide]; their doors faced north.

⁵ The upper rooms were shorter, because the galleries took up some of their space, more than from the [rooms on the] lower and middle [floors] of the building. ⁶ For the rooms were on three floors, and they didn’t have columns like those in the courtyards; therefore space was taken away from the [rooms on the] lower and middle [floors], in comparison with the ground.
