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
Ezekiel 46:20
46:20 He said to me, “This is the place where the priests will boil the guilt offering and the sin offering, and where they will bake the grain offering, so that they do not bring them out to the outer court to transmit holiness to the people.”
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.
