'Wave offering' in the Bible

Waving them for a wave offering before the Lord; this is holy for the priest, together with the waved breast and the leg which is lifted up; after that, the man may take wine.

And Aaron is to give the Levites to the Lord as a wave offering from the children of Israel, so that they may do the Lord's work.

Then the Levites are to be put before Aaron and his sons, to be offered as a wave offering to the Lord.

After that, the Levites will go in to do whatever has to be done in the Tent of meeting; you are to make them clean and give them as a wave offering.

And the Levites were made clean from sin, and their clothing was washed, and Aaron gave them for a wave offering before the Lord; and Aaron took away their sin and made them clean.

Their flesh is to be yours; like the breast of the wave offering and the right leg, it is to be yours.
