7:9But unto the sons of Kohath he gave none: because the service of the sanctuary belonging unto them was that they should bear upon their shoulders.

10:21And the Kohathites set forward, bearing the sanctuary: and the other did set up the tabernacle against they came.

4:5And when the camp setteth forward, Aaron shall come, and his sons, and they shall take down the covering vail, and cover the ark of testimony with it:

4:19But thus do unto them, that they may live, and not die, when they approach unto the most holy things: Aaron and his sons shall go in, and appoint them every one to his service and to his burden:

4:20But they shall not go in to see when the holy things are covered, lest they die.
