Ezekiel 44:30-31

Amplified Bible

³⁰ The first of all the first fruits of every kind, and every contribution and offering of every kind, from all your contributions and offerings, shall belong to the priests. You shall also give to the priest the first of your coarse meal and bread dough, so that a blessing may rest on your house. ³¹ The priests shall not eat any bird or animal that has died a natural death or has been torn to pieces.
