Ezekiel 42:13-14

13Then he said to me, “The north chambers and the south chambers, which are opposite the 1separate area, they are the 2holy chambers where the priests who are 3near to the Lord shall eat the 4most holy things. There they shall set the most holy things, the grain offering, the sin offering, and the guilt offering; for the place is holy. 14When the priests enter, they shall not go out into the outer courtyard from the sanctuary 5without 6laying their 7garments there in which they minister, for they are holy. They shall put on other garments; then they shall approach that which is for the people.”
