Albert Barnes Commentary Ezekiel 42:14

"When the priests enter in, then shall they not go out of the holy place into the outer court, but there they shall lay their garments wherein they minister; for they are holy: and they shall put on other garments, and shall approach to that which pertaineth to the people." — Ezekiel 42:14 (ASV)

Compare Leviticus 16:23.

Those things which are for the people — namely, the outer court.
