Ezekiel 44:29-31

New Revised Standard Version, Anglicised Catholic Edition

²⁹ They shall eat the grain-offering, the sin-offering, and the guilt-offering; and every devoted thing in Israel shall be theirs. ³⁰ The first of all the first fruits of all kinds, and every offering of all kinds from all your offerings, shall belong to the priests; you shall also give to the priests the first of your dough, in order that a blessing may rest on your house. ³¹ The priests shall not eat of anything, whether bird or animal, that died of itself or was torn by animals.
