Ezekiel 42:5 WEB

³  Over against the twenty [cubits] which belonged to the inner court, and over against the pavement which belonged to the outer court, was gallery against gallery in the third story.

⁴  Before the chambers was a walk of ten cubits' breadth inward, a way of one cubit; and their doors were toward the north.

⁵  Now the upper chambers were shorter; for the galleries took away from these, more than from the lower and the middle, in the building.

⁶  For they were in three stories, and they didn't have pillars as the pillars of the courts: therefore [the uppermost] was straitened more than the lowest and the middle from the ground.

⁷  The wall that was outside by the side of the chambers, toward the outer court before the chambers, the length of it was fifty cubits.
