Ezekiel 41:5-7

Amplified Bible, Classic Edition

⁵ Then he measured the wall of the temple, six cubits thick [to accommodate side chambers]; and the breadth of every side chamber, four cubits, round about the temple proper on every side.

⁶ These side chambers were three stories high, one over another and thirty in each story; and they entered into the wall which belonged to the house for the side chambers round about, that they might have hold of the wall [of the house], but they did not have hold of the wall of the temple.

⁷ And the side rooms became broader as they encompassed the temple higher and higher, for the encircling of the house went higher and higher round about the temple; therefore the breadth of the house continued upward, and so one went up from the lowest story to the highest one by way of the middle story [on a winding stairway].
