Wave-breast (חֲזֵה הִתּנוּפָה; Sept. στηθύνιον ἀφωρίσματος or τῆς ἐπιθέματος; A.V. in Ex 29:27, "breast of the wave-offering") was the breast of the victim offered in sacrifice, a ram (Ex 29:27; Nu 6:20), at the consecration of a priest or the purification of a Nazarite after his vow; or of any other animal in thank-offerings (Le 7:34; Le 10:14 sq.); or of the first-born-offering (Nu 18:18). It was so called because waved by the priest (Ex 29:27; Nu 6:20), and belonged to him (Ex 29:27; Le 7:34), to be eaten by the members of his family who were in a state of ceremonial purity (10:14).
