'Wave offering' in the Bible

and thou shall put the whole upon the hands of Aaron, and upon the hands of his sons, and shall wave them for a wave-offering before LORD.

And thou shall take the breast of Aaron's ram of consecration, and wave it for a wave-offering before LORD, and it shall be thy portion.

And thou shall sanctify the breast of the wave-offering, and the thigh of the heave-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,
