And the priest the son of Aaron shall be with the Levites, when the Levites take tithes: and the Levites shall bring up the tenth of the tithes to the house of our God, to the chambers, into the treasure house.
And it shall be Aaron's and his sons' by a statute for ever, from the children of Israel: for it is a heave-offering: and it shall be a heave-offering from the children of Israel of the sacrifice of their peace-offerings, even their heave-offering to the LORD.
And the first of all the first-fruits of all things, and every oblation of all, of every sort of your oblations, shall be the priest's: ye shall also give to the priest the first of your dough, that he may cause the blessing to rest in thy house.
And ye shall eat neither bread, nor parched corn, nor green ears, until the same day that ye have brought an offering to your God: It shall be a statute for ever throughout your generations in all your dwellings.
Thus speak to the Levites, and say to 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 a tenth part of the tithe.
