1 Kings 6:6

In order to preserve the sanctity of the temple, and at the same time allow the attachment to it of secular buildings - sleeping apartments, probably, for the priests and other attendants - Solomon made “rebatements” in the wall of the temple, or in other words built it externally in steps, thus: The beams, which formed the roof of the chambers and the floors of the upper stories, were then laid on these steps or “rests” in the wall, not piercing the wall, or causing any real union of the secular with the sacred building. It resulted from this arrangement that the lowest; chambers were the narrowest, and the uppermost considerably the widest of all, the wall receding each time by the space of a cubit.
