Ezekiel 44:17-19

New Catholic Bible

¹⁷ Whenever they approach the gates of the inner court, the priests are to wear linen vestments. They must not wear any garment of wool when they minister at the gates of the inner court or inside the temple. ¹⁸ They are to have linen turbans on their heads and linen undergarments on their loins, and they may not wear anything that might cause them to perspire.

¹⁹ Before they go out to the people in the outer court, they are to remove the clothes in which they have been performing their ministry, and they are then to put on other garments so that they will not communicate holiness to the people with their garments.
