'Sacrifice of the Peace Offering' in the Bible

From the sacrifice of the peace offerings he shall present an offering by fire to the Lord, the fat that covers the entrails and all the fat that is on the entrails,

Then he shall remove all its fat, just as the fat of the lamb is removed from the sacrifice of the peace offerings, and the priest shall offer them up in smoke on the altar, on the offerings by fire to the Lord. Thus the priest shall make atonement for him in regard to his sin which he has committed, and he will be forgiven.
