Wave offerings. In the wave offerings the priest evidently put his hands under the hands of the worshiper, who was holding the sacrifice to be presented, and waved them to and fro; or the thing offered was waved by the priest himself. (Le 23:11a) It seems that Moses, as mediator of the Law covenant, did this for Aaron and his sons when consecrating them to the priesthood. (Le 8:28, 29) This action represented a presenting of the sacrificial things to Jehovah. Certain wave offerings went to the priests as their portion.​—Ex 29:27.

Sacred portions (heave offerings). The Hebrew word teru·mahʹ is sometimes translated “sacred portion” when referring to the part of the sacrifice that was lifted up, or heaved, off the sacrifice as the portion belonging to the priests. (Ex 29:27, 28; Le 7:14, 32; 10:14, 15) The word is also frequently rendered “contribution,” when referring to the things given to the sanctuary, which, with the exception of that which was sacrificed on the altar, also went to the priests for their sustenance.​—Nu 18:8-13, 19, 24, 26-29; 31:29; De 12:6, 11.
