Leviticus 3:5

3:5 Then the sons of Aaron must offer it up in smoke on the altar atop the burnt offering that is on the wood in the fire as a gift of a soothing aroma to the Lord.

Leviticus 6:20-30

6:20 “This is the offering of Aaron and his sons which they must present to the Lord on the day when he is anointed: a tenth of an ephah of choice wheat flour as a continual grain offering, half of it in the morning and half of it in the evening. 6:21 It must be made with olive oil on a griddle and you must bring it well soaked, so you must present a grain offering of broken pieces as a soothing aroma to the Lord. 6:22 The high priest who succeeds him from among his sons must do it. It is a perpetual statute; it must be offered up in smoke as a whole offering to the Lord. 6:23 Every grain offering of a priest must be a whole offering; it must not be eaten.”

The Sin Offering

6:24 Then the Lord spoke to Moses: 6:25 “Tell Aaron and his sons, ‘This is the law of the sin offering. In the place where the burnt offering is slaughtered the sin offering must be slaughtered before the Lord. It is most holy. 6:26 The priest who offers it for sin is to eat it. It must be eaten in a holy place, in the court of the Meeting Tent. 6:27 Anyone who touches its meat must be holy, and whoever spatters some of its blood on a garment, you must wash whatever he spatters it on in a holy place. 6:28 Any clay vessel it is boiled in must be broken, and if it was boiled in a bronze vessel, then that vessel must be rubbed out and rinsed in water. 6:29 Any male among the priests may eat it. It is most holy. 6:30 But any sin offering from which some of its blood is brought into the Meeting Tent to make atonement in the sanctuary must not be eaten. It must be burned up in the fire.
