Ezekiel 44:30-31

Wycliffe Bible

³⁰ And the first things of all first engendered things, and all moist sacrifices, of all things that be offered, shall be the priests’ part; and ye shall give the first things of your meats to the priest, that he lay up blessing to his house. (And the first things of all the first begotten things, and of all the other things that be offered, shall be the portion for the priests; and ye shall give the first things of your food to the priest, so that a blessing may rest upon thy house.)

³¹ Priests shall not eat anything dead by itself, and taken of a beast, of fowls, and of sheep. (Priests shall not eat anything that dieth naturally, or is killed by a wild beast, neither bird, nor beast.)
