Numbers 18:21–23

21 “Look, I have given the Levites every tenthm in Israel as an inheritance in return for the work they do, the work of the tent of meeting. 22 The Israelites must never again come near the tent of meeting, or they will incur guilt and die. 23 The Levites will do the work of the tent of meeting, and they will bear the consequences of their iniquity. The Levites will not receive an inheritance among the Israelites;n this is a permanent statute throughout your generations.
