Ezekiel 42:2-8
42:2 Its length was 175 feet on the north side, and its width 87½ feet.
42:3 Opposite 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.
42:4 In 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.
42:5 Now the upper chambers were narrower, because the galleries took more space from them than from the lower and middle chambers of the building.
42:6 For 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.
42:7 As for the outer wall by the side of the chambers, toward the outer court facing the chambers, it was 87½ feet long.
42:8 For the chambers on the outer court were 87½ feet long, while those facing the temple were 175 feet long.
