Numbers

And the first of all the firstfruits of all things, and every oblation of all, of every sort of your oblations, shall be the priest’s: ye shall also give unto the priest the first of your dough, that he may cause the blessing to rest in thine house.

And it shall be Aaron’s and his sons’ by a statute 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 sacrifice of their peace offerings, even their heave offering unto the Lord.

Speak unto the children of Israel, and say unto them, When ye be come into the land which I give unto you, and shall reap the harvest thereof, then ye shall bring a sheaf of the firstfruits of your harvest unto the priest:

For if the firstfruit be holy, the lump is also holy: and if the root be holy, so are the branches.

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.
