Leviticus 9:21

9:21 Finally Aaron waved the breasts and the right thigh as a wave offering before the Lord just as Moses had commanded.

Leviticus 10:14

10:14 Also, the breast of the wave offering and the thigh of the contribution offering you must eat in a ceremonially ¹  clean place, you and your sons and daughters with you, for they have been given as your allotted portion and the allotted portion of your sons from the peace offering sacrifices of the Israelites. ² 

Exodus 29:24

29:24 You are to put all these ³  in Aaron’s hands ⁴  and in his sons’ hands, and you are to wave them as a wave offering ⁵  before the Lord.

¹ tn The word “ceremonially” has been supplied in the translation to clarify that the cleanness of the place specified is ritual or ceremonial in nature.

² sn Cf. Lev 7:14, 28-34 for these regulations.

³ tn Heb “the whole” or “the all.”

⁴ tn Heb “palms.”

⁵ tn The “wave offering” is תְּנוּפָה (tÿnufah); it is, of course, cognate with the verb, but an adverbial accusative rather than the direct object. In Lev 23 this seems to be a sacrificial gesture of things that are for the priests – but they present them first to Yahweh and then receive them back from him. So the waving is not side to side, but forward to Yahweh and then back to the priest. Here it is just an induction into that routine, since this is the ordination of the priests and the gifts are not yet theirs. So this will all be burned on the altar.
