And the LORD spake unto Moses, saying,(Números 18:25)

Thus 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 an heave offering of it for the LORD, even a tenth part of the tithe.(Números 18:26)

And 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.(Números 18:27)

Out 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.(Números 18:29)

Therefore thou shalt say unto them, When ye have heaved the best thereof from it, then it shall be counted unto the Levites as the increase of the threshingfloor, and as the increase of the winepress.(Números 18:30)

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.(Números 18:31)
