Numbers 18:25–32

²⁵And Jehovah spoke to Moses, saying, ²⁶And to the Levites shalt thou speak, 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 a heave-offering from it for Jehovah, the tenth of the tithe. ²⁷And your heave-offering shall be reckoned unto you, as the corn from the threshing-floor, and as the fulness of the winepress. ²⁸Thus ye also shall offer Jehovah’s heave-offering of all your tithes, which ye take of the children of Israel; and ye shall give thereof Jehovah’s heave-offering to Aaron the priest. ²⁹Out of all that is given you ye shall offer the whole heave-offering of Jehovah, —of all the best thereof the hallowed part thereof. ³⁰And thou shalt say unto them, When ye heave the best thereof from it, then it shall be counted unto the Levites as produce of the threshing-floor, and as produce of the winepress. ³¹And ye shall eat it in every place, ye and your households; for it is your reward for your service in the tent of meeting. ³²And ye shall bear no sin by reason of it, if ye heave from it the best of it; and ye shall not profane the holy things of the children of Israel, lest ye die.
