Context
21 “To the children of Levi, behold, I have given all the tithe in Israel for an inheritance, in return for their service which they serve, even the service of the Tent of Meeting.
22 Henceforth the children of Israel shall not come near the Tent of Meeting, lest they bear sin, and die.
23 But the Levites shall do the service of the Tent of Meeting, and they shall bear their iniquity. It shall be a statute forever throughout your generations. Among the children of Israel, they shall have no inheritance.
