Ezekiel 41:7 Amplified Bible (AMP)

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].
