31 Then he must remove all of its fat (just as fat was removed from the peace-offering sacrifice) and the priest must offer it up in smoke on the altar for a soothing aroma to the Lord. So the priest will make atonement[a] on his behalf and he will be forgiven.[b]
32 “‘But if he brings a sheep as his offering, for a sin offering, he must bring a flawless female. 33 He must lay his hand on the head of the sin offering and slaughter it for a sin offering in the place where the burnt offering is slaughtered.
