Albert Barnes Commentary Ezekiel 42:3

"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." — Ezekiel 42:3 (ASV)

These “chambers” did not reach the western wall; between it and them lay a court for cooking (M), probably forty by thirty cubits; this court with its approaches filled up the corner of fifty cubits square, similar to the kitchen-courts for the people. In these chambers were dining-rooms for the priests and baths, for no priest could begin his daily ministry without first bathing. “The chambers” extended beyond “the separate place” to the wall of the temple court; on the other side of this wall was the twenty-cubit space. The “pavement” (H) was undoubtedly continued along the temple wall, so that these priests’ chambers, like the thirty chambers, stood on “a pavement” and were, on the east side, opposite “this pavement.”

Translate Ezekiel 42:1-3: “Then he brought me forth into the outward court, the way toward the north, and he brought me to the chambers which were over against the separate place, and which were over against the building, toward the north along the front of the length of an hundred cubits, with the door by the north, and the breadth fifty cubits over against the twenty cubits which were in the inner court, and over against the pavement which was in the outward court, gallery upon gallery in three stories.”
