Leviticus

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 unto Aaron the priest and unto his sons by a statute for ever from among the children of Israel.

And the breasts and the right shoulder Aaron waved for a wave offering before the Lord; as Moses commanded.

And the priest shall wave them for a wave offering before the Lord: this is holy for the priest, with the wave breast and heave shoulder: and after that the Nazarite may drink wine.

And the cook took up the shoulder, and that which was upon it, and set it before Saul. And Samuel said, Behold that which is left! set it before thee, and eat: for unto this time hath it been kept for thee since I said, I have invited the people. So Saul did eat with Samuel that day.
