1 Kings 6:5-6

⁵And against the wall of the house he built stories round about, against the walls of the house round about, both of the temple and of the oracle; and he made side-chambers round about. ⁶The nethermost story was five cubits broad, and the middle was six cubits broad, and the third was seven cubits broad; for on the outside he made offsets [in the wall] of the house round about, that [the beams] should not have hold in the walls of the house.
