Leviticus 7:2-7

2In the place where they kill the burnt offering shall they kill the trespass offering: and the blood of it shall he sprinkle around upon the altar.

3And he shall offer of it all its fat; the rump, and the fat that covereth the inwards,

4And the two kidneys, and the fat that is on them, which is by the flanks, and the fat that is above the liver, with the kidneys, that shall he take away:

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

6Every male among the priests shall eat of it: 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 with it shall have it .
