4 Then present Aaron and his sons at the entrance to the Tent of Meeting and wash them with water.

3 And they shall attend to your duties and to all the duties of the Tent; but they must not come near to the furnishings of the sanctuary or the altar, or both they and you will die.
4 They are to join you and attend to the duties of the Tent of Meeting, doing all the work at the Tent; but no outsider may come near you.
