But those who were to camp in front of the tabernacle on the east, in front of the tent of meeting, were Moses, Aaron, ¹  and his sons. They were responsible for the needs ²  of the sanctuary and for the needs of the Israelites, but the unauthorized person who approached was to be put to death.

¹ The Lord said to Aaron, “You and your sons and your tribe ²  with you must bear the iniquity of the sanctuary, ³  and you and your sons with you must bear the iniquity of your priesthood.
