Ezekiel 44:28-30

And it shall be unto them for an inheritance: I am their inheritance: and ye shall give them no possession in Israel: I am their possession. They shall eat the meat offering, and the sin offering, and the trespass offering; and every dedicated thing in Israel shall be their's. 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.
