Numbers 18:22-24

Revised Standard Version

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. ²⁴ For the tithe of the people of Israel, which they present as an offering to the Lord, I have given to the Levites for an inheritance; therefore I have said of them that they shall have no inheritance among the people of Israel.”
