Ezekiel 42:14

42:14 When the priests enter, then they will not go out from the sanctuary to the outer court without taking off their garments in which they minister, for these are holy; they will put on other garments, then they will go near the places where the people are.”

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. 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.
