When they go out into the outer court where the people are, they are to take off the clothes they have been ministering in and are to leave them in the sacred rooms, and put on other clothes, so that the people are not consecrated through contact with their garments. (NIV)
And when they go out into the outer court to the people, they shall put off the garments in which they ministered and lay them in the holy chambers, and they shall put on other garments, lest by contact of their garments with the people they should consecrate (separate and set apart for holy use) such persons [unintentionally and unfittingly]. (AMP)
And when they go forth into the utter court, even into the utter court to the people, they shall put off their garments wherein they ministered, and lay them in the holy chambers, and they shall put on other garments; and they shall not sanctify the people with their garments. (KJV)
