'Heave Offering' in the Bible

But upon my holy hill, even upon the high hill of Israel shall all the house of Israel and all that is in the land worship me: and in the same place will I favour them, and there will I require your heave offerings, and the firstlings of your oblations, with all your holy things.

"This is the heave offering, that ye shall give to be heaved: namely, the sixteenth part of an Ephah, out of a Homer of wheat: and the sixteenth part of an Ephah, out of a Homer of barley.

All the people of the land shall give this heave offering with a free will.
