Ezekiel 44:29-31

44:29 They may eat the grain offering, the sin offering, and the guilt offering, and every devoted thing in Israel will be theirs. 44:30 The first of all the first fruits and all contributions of any kind will be for the priests; you will also give to the priest the first portion of your dough, so that a blessing may rest on your house. 44:31 The priests will not eat any bird or animal that has died a natural death or was torn to pieces by a wild animal.
