Ezekiel 41:7

41:7 The side chambers surrounding the temple were wider at each successive story; for the structure surrounding the temple went up story by story all around the temple. For this reason the width of the temple increased as it went up, and one went up from the lowest story to the highest by the way of the middle story.

Ezekiel 44:19

44:19 When they go out to the outer court to the people, they must remove the garments they were ministering in, and place them in the holy chambers; they must put on other garments so that they will not transmit holiness to the people with their garments.
