Leviticus 7:34 For the wave-breast and the heave-shoulder have I taken of the children of Israel from off the sacrifices of their peace-offerings, and have given them to Aaron the priest, and to his sons, by a statute for ever, from among the children of Israel. (WBS)
Leviticus 10:15 The heave-shoulder and the wave-breast shall they bring, with the offerings made by fire of the fat, to wave it for a wave-offering before the LORD; and it shall be thine, and thy sons' with thee, by a statute for ever; as the LORD hath commanded. (WBS)
