Leviticus 7:33

‘Now if his offering is a sacrifice of peace offerings, if he is going to bring near one from the herd, whether male or female, he shall bring it near without blemish before Yahweh.

‘Then Aaron’s sons shall offer it up in smoke on the altar on the burnt offering, which is on the wood that is on the fire; it is an offering by fire of a soothing aroma to Yahweh.

Moses also took the breast and waved it as a wave offering before Yahweh; it was Moses’ portion of the ram of ordination, just as Yahweh had commanded Moses.

But the breasts and the right thigh Aaron waved as a wave offering before Yahweh, just as Moses had commanded.

“The breast of the wave offering, however, and the thigh of the contribution offering you may eat in a clean place, you and your sons and your daughters with you; for they have been given as a statute for you and a statute for your sons taken out of the sacrifices of the peace offerings of the sons of Israel.

‘And the priest shall take the ram’s shoulder when it has been boiled, and one unleavened cake out of the basket and one unleavened wafer, and shall put them on the hands of the Nazirite after he has shaved the hair of his Nazirite vow.

Then Yahweh spoke to Aaron, “Now behold, I Myself have given you the responsibility of My contributions, even all the holy gifts of the sons of Israel I have given them to you as a portion and to your sons as a perpetual statute.

“Now this shall be the legal judgment for the priests taken from the people, from those who offer a sacrifice, either an ox or a sheep: they shall give to the priest the shoulder and the two cheeks and the stomach.

And this was the legal judgment for the priests with the people: when any man was offering a sacrifice, the priest’s young man would come while the meat was boiling, with a three-pronged fork in his hand.

Then the cook took up the leg with what was on it and set it before Saul. And Samuel said, “Here is what has been reserved! Set it before you and eat, because it has been kept for you until the appointed time, since I said I have invited the people.” So Saul ate with Samuel that day.

Do you not know that those who perform sacred services eat the food of the temple, and those who attend regularly to the altar have their share from the altar?
