Leviticus 4:31-33 Christian Standard Bible (CSB)
31 He is to remove all its fat just as the fat is removed from the fellowship sacrifice. The priest is to burn it on the altar as a pleasing aroma to the Lord. In this way the priest will make atonement on his behalf, and he will be forgiven.
32 “Or if the offering that he brings as a sin offering is a lamb, he is to bring an unblemished female. 33 He is to lay his hand on the head of the sin offering and slaughter it as a sin offering at the place where the burnt offering is slaughtered.
