Ezekiel 40:21-22

21Here, too, there were three guard alcoves on each side, with dividing walls and an entry room. All the measurements matched those of the east gateway. The gateway passage was 87-1/2 feet long and 43-3/4 feet wide between the back walls of facing guard alcoves.

22The windows, the entry room, and the palm tree decorations were identical to those in the east gateway. There were seven steps leading up to the gateway entrance, and the entry room was at the inner end of the gateway passage.
