Numbers 18:21–26

²¹“To the sons of Levi, behold, I have given all the ^atithe in Israel for an inheritance, in return for their service which they perform, the service of the tent of meeting.

²²“^aThe sons of Israel shall not come near the tent of meeting again, or they will bear sin and die.

²³“Only the Levites shall perform the service of the tent of meeting, and they shall ^abear their iniquity; it shall be a perpetual statute throughout your generations, and among the sons of Israel ^bthey shall have no inheritance.

²⁴“For the tithe of the sons of Israel, which they offer as an offering to the Lord, I have given to the Levites for an inheritance; therefore I have said concerning them, ‘^aThey shall have no inheritance among the sons of Israel.’ ”

²⁵Then the Lord spoke to Moses, saying,

²⁶“Moreover, you shall speak to the Levites and say to them, ‘When you take from the sons of Israel ^athe tithe which I have given you from them for your inheritance, then you shall present an offering from it to the Lord, a ^btithe of the tithe.
