Leviticus 4:3, 21, 31, 35

“If the high priest sins, bringing guilt upon the entire community, he must give a sin offering for the sin he has committed. He must present to the LORD a young bull with no defects.

Then the priest must take what is left of the bull and carry it outside the camp and burn it there, just as is done with the sin offering for the high priest. This offering is for the sin of the entire congregation of Israel.

Then he must remove all the goat’s fat, just as he does with the fat of the peace offering. He will burn the fat on the altar, and it will be a pleasing aroma to the LORD. Through this process, the priest will purify the people, making them right with the LORD, and they will be forgiven.

Then he must remove all the sheep’s fat, just as he does with the fat of a sheep presented as a peace offering. He will burn the fat on the altar on top of the special gifts presented to the LORD. Through this process, the priest will purify the people from their sin, making them right with the LORD, and they will be forgiven.
