Yehezkiel 44:11

44:11 Yet they will be ministers in my sanctuary, having oversight at the gates of the temple, and serving the temple. They will slaughter the burnt offerings and the sacrifices for the people, and they will stand before them to minister to them.

Yehezkiel 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.
