'Sacrifice of the Peace Offering' in the Bible

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

(just as these are removed from the ox of the sacrifice of peace offerings), and the priest is to offer them up in smoke on the altar of burnt offering.

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 it up in smoke on the altar, on the offerings by fire to the Lord. In this way the priest shall make atonement for him in regard to the sin which he has committed, and he will be forgiven.
