Exodus

And Moses took the breast, and waved it for a wave offering before the Lord: for of the ram of consecration it was Moses’ part; as the Lord commanded Moses.

And the priest shall burn the fat upon the altar: but the breast shall be Aaron’s and his sons’.

Moses and Aaron among his priests, and Samuel among them that call upon his name; they called upon the Lord, and he answered them.

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 thou shalt put all in the hands of Aaron, and in the hands of his sons; and shalt wave them for a wave offering before the Lord.
