28 Thus ye also shall offer a heave-offering to the LORD of all your tithes which ye receive of the children of Israel; and ye shall give of them the LORD'S heave-offering to Aaron the priest.
29 Out of all your gifts ye shall offer every heave-offering of the LORD, of all the best of it, even its hallowed part out of it.
30 Therefore thou shalt say to them, When ye have heaved from it the best of it, then it shall be counted to the Levites as the increase of the threshing-floor, and as the increase of the wine-press.
31 And ye shall eat it in every place, ye and your households: for it is your reward for your service in the tabernacle of the congregation.
32 And ye shall bear no sin by reason of it, when ye have heaved from it the best of it: neither shall ye pollute the holy things of the children of Israel, lest ye die.
