Ezekiel 41:6-8

Amplified Bible, Classic Edition

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].

⁸ I saw also that the temple had an elevation or foundation platform round about it. The foundations of the side chambers measured a full reed measure of six long cubits.
