'Wave offering' in the Bible

You shall put all of this in Aaron's hands, and in his sons' hands, and shall wave them for a wave offering before Yahweh.

"You shall take the breast of Aaron's ram of consecration, and wave it for a wave offering before Yahweh: and it shall be your portion.

You shall sanctify the breast of the wave offering, and the thigh of the wave offering, which is waved, and which is heaved up, of the ram of consecration, even of that which is for Aaron, and of that which is for his sons:

and it shall be for Aaron and his sons as their portion forever from the children of Israel; for it is a wave offering: and it shall be a wave offering from the children of Israel of the sacrifices of their peace offerings, even their wave offering to Yahweh.
