1 Kings 6:5
Against the walls of the temple and the inner sanctuary, Solomon built a chambered structure around the temple, in which he constructed the side rooms.
Berean Standard Bible
And against the wall of the house he built chambers round about, against the walls of the house round about, both of the temple and of the oracle: and he made chambers round about:
Against the wall of the house, he built floors all around, against the walls of the house all around, both of the temple and of the inner sanctuary; and he made side rooms all around.
