side chamber
Ezekiel 41:6
The side chambers were in three stories, one above another, and thirty in each story; and the side chambers extended to the wall which [stood] on their inward side all around, that they might be fastened, and not be fastened into the wall of the temple [itself].
Ezekiel 41:7
The side chambers surrounding the temple were wider at each successive story. Because the structure surrounding the temple went upward by stages on all sides of the temple, therefore the width of the temple [increased] as it went higher; and thus one went up from the lowest [story] to the highest by way of the second [story].
Ezekiel 42:3-14
Opposite the twenty [cubits] which belonged to the inner court, and opposite the pavement which belonged to the outer court, [was] gallery corresponding to gallery in three stories.
Before the chambers [was] an inner walk ten cubits wide, a way of one [hundred] cubits; and their openings [were] on the north.
Now the upper chambers [were] smaller because the galleries took more [space] away from them than from the lower and middle ones in the building.
For they [were] in three stories and had no pillars like the pillars of the courts; therefore [the upper chambers] were set back from the ground upward, more than the lower and middle ones.
As for the outer wall by the side of the chambers, toward the outer court facing the chambers, its length [was] fifty cubits.
For the length of the chambers which [were] in the outer court [was] fifty cubits; and behold, [the length of those] facing the temple [was] a hundred cubits.
Below these chambers [was] the entrance on the east side, as one enters them from the outer court.
In the thickness of the wall of the court toward the east, facing the separate area and facing the building, [there were] chambers.
The way in front of them [was] like the appearance of the chambers which [were] on the north, according to their length so was their width, and all their exits [were] both according to their arrangements and openings.
Corresponding to the openings of the chambers which were toward the south was an opening at the head of the way, the way in front of the wall toward the east, as one enters them.
Then he said to me, "The north chambers [and] the south chambers, which are opposite the separate area, they are the holy chambers where the priests who are near to the LORD shall eat the most holy things. There they shall lay the most holy things, the grain offering, the sin offering and the guilt offering; for the place is holy.
"When the priests enter, then they shall not go out into the outer court from the sanctuary without laying there their garments in which they minister, for they are holy. They shall put on other garments; then they shall approach that which is for the people."
1 Kings 6:5
Against the wall of the house he built stories encompassing the walls of the house around both the nave and the inner sanctuary; thus he made side chambers all around.
1 Kings 6:6
The lowest story [was] five cubits wide, and the middle [was] six cubits wide, and the third [was] seven cubits wide; for on the outside he made offsets [in the wall] of the house all around in order that [the beams] would not be inserted in the walls of the house.
