Ezekiel 44:17-19

17“ ‘When they enter the gates of the inner court, they are to wear linen clothes; they must not wear any woolen garment while ministering at the gates of the inner court or inside the temple.

18They are to wear linen turbans on their heads and linen undergarments around their waists. They must not wear anything that makes them perspire.

19When they go out into the outer court where the people are, they are to take off the clothes they have been ministering in and are to leave them in the sacred rooms, and put on other clothes, so that the people are not consecrated through contact with their garments.
