'Wave offerings' in the Bible

The LORD spoke to Aaron, "I, behold, I have given you the command of my wave offerings, even all the holy things of the children of Israel; to you have I given them by reason of the anointing, and to your sons, as a portion forever.

"This is yours, too: the wave offering of their gift, even all the wave offerings of the children of Israel. I have given them to you, and to your sons and to your daughters with you, as a portion forever. Everyone who is clean in your house shall eat of it.

All the wave offerings of the holy things, which the children of Israel offer to the LORD, have I given you, and your sons and your daughters with you, as a portion forever: it is a covenant of salt forever before the LORD to you and to your seed with you."
