'Wave Offering' in the Bible

"Then Aaron is to present the descendants of Levi as a wave offering before the LORD from the Israelis, because they are to work in the service of the LORD.

You are to make the descendants of Levi stand in the presence of Aaron and his sons. Then you are to wave them as wave offerings to the LORD.

"After this, the descendants of Levi are to come to serve at the appointed place of meeting, after you have purified them and presented them as wave offerings,

The descendants of Levi therefore purified themselves, washed their clothes, and then Aaron presented them as wave offerings to the LORD. Aaron provided atonement for them to purify them.

The raised offering and wave offerings presented by the Israelis are yours, too. I've given them to you, to your sons, and to your daughters as a prescribed apportionment forever. Everyone who is clean in your household may eat it.

Their meat is to belong to you, just as the breast wave offering and the right thigh is yours.
