Numbers 18:21-28 And, behold, I have given the children of Levi all the tenth in Israel for an inheritance, for their service which they serve, even the service of the tabernacle of meeting.

KJ2000⁽ⁱ⁾ ²¹ And, behold, I have given the children of Levi all the tenth in Israel for an inheritance, for their service which they serve, even the service of the tabernacle of meeting. ²² Neither must the children of Israel henceforth come near the tabernacle of meeting, lest they bear sin, and die. ²³ But the Levites shall do the service of the tabernacle of meeting, and they shall bear their iniquity: it shall be a statute forever throughout your generations, that among the children of Israel they have no inheritance. ²⁴ But the tithes of the children of Israel, which they offer as a heave offering unto the LORD, I have given to the Levites to inherit: therefore I have said unto them, Among the children of Israel they shall have no inheritance. ²⁵ And the LORD spoke unto Moses, saying, ²⁶ Thus speak unto the Levites, and say unto them, When you take of the children of Israel the tithes which I have given you from them for your inheritance, then you shall offer up a heave offering of it for the LORD, even a tenth part of the tithe. ²⁷ And this your heave offering shall be reckoned unto you, as though it were the grain of the threshing floor, and as the fullness of the winepress. ²⁸ Thus you also shall offer a heave offering unto the LORD of all your tithes, which you receive of the children of Israel; and you shall give thereof the LORD'S heave offering to Aaron the priest.
