For they were in three stories, but had not pillars as the pillars of the courts: therefore the building was straitened more than the lowest and the middlemost from the ground.
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].
1 Kings 6:8
The doorway for the lowest side chamber [was] on the right side of the house; and they would go up by winding stairs to the middle [story], and from the middle to the third.
