Leviticus 7:30

30. A wave offering The rabbies say that the offering was laid upon the hands of the offerer. The priest, putting his hands beneath, moves the offering to and fro horizontally. But it is not certain from Exodus 29:26-27 whether the waving was done by the offerer alone or by the help of the priest. The significance of this peculiar motion is doubtful. The rabbies say that it symbolically teaches that Jehovah is present in every quarter of the earth. The breast thus waved was eaten by the priest and his family.
