Ezekiel 41:6-7
6 And the side-chambers were in three stories, one over another, and thirty in order; and they entered into the wall which belonged to the house for the side-chambers round about, that they might have hold `therein', and not have hold in the wall of the house.
7 And the side-chambers were broader as they encompassed `the house' higher and higher; for the encompassing of the house went higher and higher round about the house: therefore the breadth of the house `continued' upward; and so one went up `from' the lowest `chamber' to the highest by the middle `chamber'.
