Leviticus 4:10

(just as these are taken from the ox of the sacrifice of the peace offerings ); and the priest shall burn them on the altar of burnt offering .

just as the fat is removed from the ox sacrificed as a fellowship offering. Then the priest shall burn them on the altar of burnt offering.

As it was taken off from the bullock of the sacrifice of peace offerings : and the priest shall burn them upon the altar of the burnt offering.
