Yehezkiel 44:17-19

44:17 “‘When they enter the gates of the inner court, they must wear linen garments; they must not have any wool on them when they minister in the inner gates of the court and in the temple. 44:18 Linen turbans will be on their heads and linen undergarments will be around their waists; they must not bind themselves with anything that causes sweat. 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. ¹ 

[44:19]  ¹ sn For a similar concept of the transmitting of holiness, see Exod 19:12-14; Lev 10:1-2; 2 Sam 6:7. Similar laws concerning the priest are found in Lev 10 and 21.
