Ezekiel 42:3-5

3Opposite the 35 foot space belonging to the inner court and opposite the paved surface belonging to the outer court, the structure rose gallery by gallery in three tiers.

4In front of the chambers was a walkway toward the inside, 17½ feet wide and 175 feet long, and their entrances were on the north.

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