Ezekiel 42:12

And according to the doors of the chambers that were toward the south was a door in the head of the way, literally. "And like their doors," namely, those of the cells toward the north, "so were also the doors of the cells toward the south: an opening was at the head of the way,'' where the passages connecting the cell-buildings came together, even the way directly before the wall toward the east, as one entereth into them, as one approached the cells.
