Leviticus 7:30

After the beast was killed, and the parts of it divided, the priest was to put the parts mentioned into the hands of the offerer. See Exodus 29:22. Made by fire; so called not strictly, as burnt-offerings are, because some parts of these were left for the priest, Leviticus 7:31; but more largely, because even these peace-offerings were in part, though not wholly, burnt. The breast may be waved to and fro by his hands, which were supported and directed by the hands of the priest.
