19 Then the Lord spoke to Moses, saying, 20 “This is the offering which Aaron and his sons are to present to the Lord on the day when he is anointed; the tenth of an ephah of fine flour as a [i]regular grain offering, half of it in the morning and half of it in the evening. 21 It shall be prepared with oil on a griddle. When it is well stirred, you shall bring it. You shall present the grain offering in baked pieces as a soothing aroma to the Lord. 22 The anointed priest who will be in his place [j]among his sons shall [k]offer it. By a permanent ordinance it shall be entirely offered up in smoke to the Lord. 23 So every grain offering of the priest shall be burned entirely. It shall not be eaten.”
24 Then the Lord spoke to Moses, saying, 25 “Speak to Aaron and to his sons, saying, ‘This is the law of the sin offering: in the place where the burnt offering is slain the sin offering shall be slain before the Lord; it is most holy. 26 The priest who offers it for sin shall eat it. It shall be eaten in a holy place, in the court of the tent of meeting. 27 Anyone who touches its flesh will become consecrated; and when any of its blood [l]splashes on a garment, in a holy place you shall wash what was splashed on. 28 Also the earthenware vessel in which it was boiled shall be broken; and if it was boiled in a bronze vessel, then it shall be scoured and rinsed in water. 29 Every male among the priests may eat of it; it is most holy. 30 But no sin offering of which any of the blood is brought into the tent of meeting to make atonement in the holy place shall be eaten; it shall be burned with fire.
Basically, if the sacrifice was for the priest, whether in ordination or sin, including the sacrifice for the sins of the community, then it was to be burned completely. The priest were not to partake whatsoever in such a sacrifice, since it was offered on their behalf. It reminds me of a story in the book of Acts, where a couple sells a piece of property to give the money to God. But after they’ve sold it they had second thoughts and decided to keep some of the money back. God didn’t take this lightly, they didn’t just get a reprimand. The couple received death for trying to deceive God and their fellow Christians. We need to be honest and forthright in our giving, not trying to do it for a show or a status symbol.
