Ezekiel 41:5-6
Context41:5 Then he measured the wall of the temple 1 as 10½ feet, 2 and the width of the side chambers as 7 feet, 3 all around the temple. 41:6 The side chambers were in three stories, one above the other, thirty in each story. There were offsets in the wall all around to serve as supports for the side chambers, so that the supports were not in the wall of the temple.
