And thou shalt sanctify the breast of the wave offering, and the shoulder of the heave offering, which is waved, and which is heaved up, of the ram of the consecration, even of that which is for Aaron, and of that which is for his sons: And it shall be Aaron's and his sons' by a statute for ever from the children of Israel: for it is an heave offering: and it shall be an heave offering from the children of Israel of the sacrifice of their peace offerings, even their heave offering unto the LORD. And the holy garments of Aaron shall be his sons' after him, to be anointed therein, and to be consecrated in them. And that son that is priest in his stead shall put them on seven days, when he cometh into the tabernacle of the congregation to minister in the holy place. read more
And the priest shall take one he lamb, and offer him for a trespass offering, and the log of oil, and wave them for a wave offering before the LORD: And he shall slay the lamb in the place where he shall kill the sin offering and the burnt offering, in the holy place: for as the sin offering is the priest's, so is the trespass offering: it is most holy:
Moreover, when ye shall divide by lot the land for inheritance, ye shall offer an oblation unto the LORD, an holy portion of the land: the length shall be the length of five and twenty thousand reeds, and the breadth shall be ten thousand. This shall be holy in all the borders thereof round about. Of this there shall be for the sanctuary five hundred in length, with five hundred in breadth, square round about; and fifty cubits round about for the suburbs thereof. And of this measure shalt thou measure the length of five and twenty thousand, and the breadth of ten thousand: and in it shall be the sanctuary and the most holy place. The holy portion of the land shall be for the priests the ministers of the sanctuary, which shall come near to minister unto the LORD: and it shall be a place for their houses, and an holy place for the sanctuary.
And it shall be unto them for an inheritance: I am their inheritance: and ye shall give them no possession in Israel: I am their possession. They shall eat the meat offering, and the sin offering, and the trespass offering; and every dedicated thing in Israel shall be theirs. And the first of all the firstfruits of all things, and every oblation of all, of every sort of your oblations, shall be the priest's: ye shall also give unto the priest the first of your dough, that he may cause the blessing to rest in thine house. The priests shall not eat of any thing that is dead of itself, or torn, whether it be fowl or beast.
1 Samuel 2:13-14
And the priests' custom with the people was, that, when any man offered sacrifice, the priest's servant came, while the flesh was in seething, with a fleshhook of three teeth in his hand; And he struck it into the pan, or kettle, or caldron, or pot; all that the fleshhook brought up the priest took for himself. So they did in Shiloh unto all the Israelites that came thither.
And this shall be the priest's due from the people, from them that offer a sacrifice, whether it be ox or sheep; and they shall give unto the priest the shoulder, and the two cheeks, and the maw. The firstfruit also of thy corn, of thy wine, and of thine oil, and the first of the fleece of thy sheep, shalt thou give him. For the LORD thy God hath chosen him out of all thy tribes, to stand to minister in the name of the LORD, him and his sons for ever.
And the LORD spake unto Aaron, Behold, I also have given thee the charge of mine heave offerings of all the hallowed things of the children of Israel; unto thee have I given them by reason of the anointing, and to thy sons, by an ordinance for ever. This shall be thine of the most holy things, reserved from the fire: every oblation of theirs, every meat offering of theirs, and every sin offering of theirs, and every trespass offering of theirs, which they shall render unto me, shall be most holy for thee and for thy sons. In the most holy place shalt thou eat it; every male shall eat it: it shall be holy unto thee. And this is thine; the heave offering of their gift, with all the wave offerings of the children of Israel: I have given them unto thee, and to thy sons and to thy daughters with thee, by a statute for ever: every one that is clean in thy house shall eat of it. read more
And the priest shall take the sodden shoulder of the ram, and one unleavened cake out of the basket, and one unleavened wafer, and shall put them upon the hands of the Nazarite, after the hair of his separation is shaven: And the priest shall wave them for a wave offering before the LORD: this is holy for the priest, with the wave breast and heave shoulder: and after that the Nazarite may drink wine.
And Moses spake unto Aaron, and unto Eleazar and unto Ithamar, his sons that were left, Take the meat offering that remaineth of the offerings of the LORD made by fire, and eat it without leaven beside the altar: for it is most holy: And ye shall eat it in the holy place, because it is thy due, and thy sons' due, of the sacrifices of the LORD made by fire: for so I am commanded. And the wave breast and heave shoulder shall ye eat in a clean place; thou, and thy sons, and thy daughters with thee: for they be thy due, and thy sons' due, which are given out of the sacrifices of peace offerings of the children of Israel.
And he shall bring it to Aaron's sons the priests: and he shall take thereout his handful of the flour thereof, and of the oil thereof, with all the frankincense thereof; and the priest shall burn the memorial of it upon the altar, to be an offering made by fire, of a sweet savour unto the LORD: And the remnant of the meat offering shall be Aaron's and his sons': it is a thing most holy of the offerings of the LORD made by fire.
And the priest shall burn the fat upon the altar: but the breast shall be Aaron's and his sons'. And the right shoulder shall ye give unto the priest for an heave offering of the sacrifices of your peace offerings. He among the sons of Aaron, that offereth the blood of the peace offerings, and the fat, shall have the right shoulder for his part. For the wave breast and the heave shoulder have I taken of the children of Israel from off the sacrifices of their peace offerings, and have given them unto Aaron the priest and unto his sons by a statute for ever from among the children of Israel.
Every male among the priests shall eat thereof: it shall be eaten in the holy place: it is most holy. As the sin offering is, so is the trespass offering: there is one law for them: the priest that maketh atonement therewith shall have it. And the priest that offereth any man's burnt offering, even the priest shall have to himself the skin of the burnt offering which he hath offered. And all the meat offering that is baken in the oven, and all that is dressed in the fryingpan, and in the pan, shall be the priest's that offereth it. read more
The priest that offereth it for sin shall eat it: in the holy place shall it be eaten, in the court of the tabernacle of the congregation.
And he shall take of it his handful, of the flour of the meat offering, and of the oil thereof, and all the frankincense which is upon the meat offering, and shall burn it upon the altar for a sweet savour, even the memorial of it, unto the LORD. And the remainder thereof shall Aaron and his sons eat: with unleavened bread shall it be eaten in the holy place; in the court of the tabernacle of the congregation they shall eat it. It shall not be baken with leaven. I have given it unto them for their portion of my offerings made by fire; it is most holy, as is the sin offering, and as the trespass offering. All the males among the children of Aaron shall eat of it. It shall be a statute for ever in your generations concerning the offerings of the LORD made by fire: every one that toucheth them shall be holy.
And he shall make amends for the harm that he hath done in the holy thing, and shall add the fifth part thereto, and give it unto the priest: and the priest shall make an atonement for him with the ram of the trespass offering, and it shall be forgiven him.
Then shall he bring it to the priest, and the priest shall take his handful of it, even a memorial thereof, and burn it on the altar, according to the offerings made by fire unto the LORD: it is a sin offering. And the priest shall make an atonement for him as touching his sin that he hath sinned in one of these, and it shall be forgiven him: and the remnant shall be the priest's, as a meat offering.
1 Corinthians 9:13
Do ye not know that they which minister about holy things live of the things of the temple? and they which wait at the altar are partakers with the altar?
