LEV 4:35

35 And he shall remove all the chelev [(fat)] thereof, just as the chelev [(fat)] of the keves [(lamb)] is taken away from the zevach hashelamim [(sacrifice of the peace offerings)]; and the kohen shall burn them upon the Mizbe'ach, according to the offerings made by eish unto Hashem; and the kohen shall make kapporah for his chattat [(sin)] that he hath sinned, and it shall be forgiven him.
