Albert Barnes Commentary Ezekiel 42:1

"Then he brought me forth into the outer court, the way toward the north: and he brought me into the chamber that was over against the separate place, and which was over against the building toward the north." — Ezekiel 42:1 (ASV)

Utter court - Outward court, as in Ezekiel 42:3.

Into the chamber ... before the building - This refers to the chambers (See L, Plan II)... opposite, and so on. “The building” is the temple building, for this row of chambers was built against eighty cubits of the wall bounding “the separate place” and twenty cubits of the wall of the temple court.
