Numbers 18:21–30

²¹And behold, ^rI have given the children of Levi all the tenth in Israel for an inheritance, for their service which they serve, even ^sthe service of the tabernacle of the congregation. ^22tNeither must the children of Israel henceforth come nigh the tabernacle of the congregation, ^ulest they bear sin, and die. ²³But the Levites ^wshall do the service of the tabernacle of the congregation, and ^xthey shall bear their iniquity: it shall be a statute for ever throughout your generations, that among the children of Israel they have no inheritance. ²⁴But the tithes of the children of Israel, which ^ythey offer as a heave offering unto the Lord, I have given to the Levites to inherit: therefore I have said unto them, ^zAmong the children of Israel they shall have no inheritance.

²⁵And the Lord spake unto Moses, saying, ²⁶Thus speak unto the Levites, and say unto them, When ye take of the children of Israel the tithes which I have given you from them for your inheritance, then ye shall offer up a heave offering of it for the Lord, even ^aa tenth part of the tithe. ^27bAnd this your heave offering shall be reckoned unto you, as though it were the corn of the threshingfloor, and as the fulness of the winepress. ²⁸Thus you also shall offer a heave offering unto the Lord of all your tithes, which ye receive of the children of Israel; and ye shall give thereof the Lord’s heave offering to Aaron the priest. ²⁹Out of all your gifts ye shall offer every heave offering of the Lord, of all the best thereof, even the hallowed part thereof out of it. ³⁰Therefore thou shalt say unto them, When ye have heaved the best thereof from it, ^cthen it shall be counted unto the Levites as the increase of the threshingfloor, and as the increase of the winepress.
