Ezekiel 41:5

Having left the holy of holies measured in the 3rd verse, now he is come to take the measures of the outer wall. The house; the temple itself, Six cubits; three yards thick was this wall from the ground to the first story of the side chambers. Every side chamber of the lowest floor; for there were three stories of these, and they differed in their breadth, as the wall of the temple on which they rested abated of its thickness; for the middle chambers were broader than the lowest by a cubit, and the highest as much broader than the middle. Round about; on the north, south, and west parts. On every side; on each side of every one of these three gates. The east gate, and buildings about that, were not faced with such facings.
