Leviticus 7:8 (KJV)

And he shall offer of it all the fat thereof; the rump, and the fat that covereth the inwards,

And the two kidneys, and the fat that is on them, which is by the flanks, and the caul that is above the liver, with the kidneys, it shall he take away:

And the priest shall burn them upon the altar for an offering made by fire unto the LORD: it is a trespass offering.

Every male among the priests shall eat thereof: it shall be eaten in the holy place: it is most holy.

As the sin offering is, so is the trespass offering: there is one law for them: the priest that maketh atonement therewith shall have it.

And all the meat offering that is baken in the oven, and all that is dressed in the fryingpan, and in the pan, shall be the priest's that offereth it.

And every meat offering, mingled with oil, and dry, shall all the sons of Aaron have, one as much as another.

And this is the law of the sacrifice of peace offerings, which he shall offer unto the LORD.

If he offer it for a thanksgiving, then he shall offer with the sacrifice of thanksgiving unleavened cakes mingled with oil, and unleavened wafers anointed with oil, and cakes mingled with oil, of fine flour, fried.

Besides the cakes, he shall offer for his offering leavened bread with the sacrifice of thanksgiving of his peace offerings.
