Numbers 18:21-24

“Behold, I have given the Levites all the tithe in Israel as an inheritance, in return for their service which they perform, the service of the Tent of Meeting (tabernacle). The Israelites shall never again approach the Tent of Meeting [the covered sanctuary, the Holy Place, and the Holy of Holies], or they [who do] will incur sin and die. Only the Levites shall perform the service of the Tent of Meeting (tabernacle), and they shall bear their iniquity; it shall be a statute forever throughout your generations, that the Levites shall have no inheritance [of land] among the children of Israel. But the tithe of the Israelites, which they present as an offering to the LORD, I have given to the Levites as an inheritance; therefore I have said to them, ‘They shall have no inheritance among the children of Israel.’ ”
