Ezekiel 42:3-6

3Opposite the 35 feet that belonged to the inner court, and opposite the pavement which belonged to the outer court, gallery faced gallery in the three stories.

4In front of the chambers was a walkway on the inner side, 17½ feet wide at a distance of 1¾ feet, and their entrances were on the north.

5Now the upper chambers were narrower, because the galleries took more space from them than from the lower and middle chambers of the building.

6For they were in three stories and had no pillars like the pillars of the courts; therefore the upper chambers were set back from the ground more than the lower and upper ones.
