Numbers 18:21-23

Revised Standard Version

²¹ “To the Levites I have given every tithe in Israel for an inheritance, in return for their service which they serve, their service in the tent of meeting. ²² And henceforth the people 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 perpetual statute throughout your generations; and among the people of Israel they shall have no inheritance.
