And the priest the son of Aaron shall be with the Levites, when the Levites take tithes: and the Levites shall bring up the tithe of the tithes unto the house of our God, to the chambers, into the treasure house.
and it shall be for Aaron and his sons as a due for ever from the children of Israel: for it is an heave offering: and it shall be an heave offering from the children of Israel of the sacrifices of their peace offerings, even their heave offering unto the LORD.
And the first of all the firstfruits of every thing, and every oblation of every thing, of all your oblations, shall be for the priests: ye shall also give unto the priest the first of your dough, to cause a blessing to rest on thine house.
And ye shall eat neither bread, nor parched corn, nor fresh ears, until this selfsame day, until ye have brought the oblation of your God: it is a statute for ever throughout your generations in all your dwellings.
Moreover thou shalt speak unto the Levites, and say unto them, When ye take of the children of Israel the tithe which I have given you from them for your inheritance, then ye shall offer up an heave offering of it for the LORD, a tithe of the tithe.
