Ezekiel 42:9

7The wall that was outside by the side of the rooms, toward the outer court before the rooms, was fifty cubits long.

8For the length of the rooms that were in the outer court was fifty cubits. Behold, those facing the temple were one hundred cubits.

9From under these rooms was the entry on the east side, as one goes into them from the outer court.

10In the thickness of the wall of the court toward the east, before the separate place, and before the building, there were rooms.

11The way before them was like the appearance of the rooms which were toward the north. Their length and width were the same. All their exits had the same arrangement and doors.
