Leviticus 7:34

“Then you shall take the breast of Aaron’s ram of ordination and wave it as a wave offering before Yahweh; and it shall be your portion.

‘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.

‘It is a perpetual statute throughout your generations in all your places of habitation: you shall not eat any fat or any blood.’”

‘And you shall give the right thigh to the priest as a contribution from the sacrifices of your peace offerings.

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.

“The thigh contributed by raising up and the breast offered by waving they shall bring along with the offerings by fire of the portions of fat, to wave as a wave offering before Yahweh; so it shall be a perpetual statute for you and your sons with you, just as Yahweh has commanded.”

‘Also every contribution pertaining to all the holy gifts of the sons of Israel, which they bring near to the priest, shall be his.

‘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.

“Aaron then shall present the Levites before Yahweh as a wave offering from the sons of Israel, that they may be qualified to perform the service of Yahweh.

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.

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?
