Ezekiel Chapter 41 Vs. 6

 The Inner Temple

And the side chambers were three, one over another, and thirty in order; and they entered into the wall which was of the house for the side chambers round about, that they might have hold, but they had not hold in the wall of the house. Eze 41:6

not hold in... It seems that the rooms were not built against the temple walls but against other walls facing them.

There seemed to be 30 of these chambers which were 6 feet wide at the lowest level.

Surrounding the temple were three levels of side rooms… one above another, 30 on each level.
