Leviticus 7:6 KJV

4And 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:

5And the priest shall burn them upon the altar for an offering made by fire unto the LORD: it is a trespass offering.

6Every male among the priests shall eat thereof: it shall be eaten in the holy place: it is most holy.

7As the sin offering is, so is the trespass offering: there is one law for them: the priest that maketh atonement therewith shall have it.

8And the priest that offereth any man’s burnt offering, even the priest shall have to himself the skin of the burnt offering which he hath offered.
