'Ministering' in the Bible

Yet they will occupy My sanctuary, serving as guards at the temple gates and ministering at the temple. They will slaughter the burnt offerings and other sacrifices for the people and will stand before them to serve them.

Before they go out to the outer court, to the people, they must take off the clothes they have been ministering in, leave them in the holy chambers, and dress in other clothes so that they do not transmit holiness to the people through their clothes.
