A heave offering is a term used in ancient times to describe a portion of an offering to God that was lifted up and given to the priests. This was typically a voluntary act of giving in addition to the required offerings. Synonyms for heave offering include a wave offering, an elevation offering, or a presentation offering. The wave offering was similar to the heave offering in that it was lifted up and presented to God, but it was waved back and forth instead of being moved up and down. The elevation offering was also lifted up, but it was presented as a burnt sacrifice. The presentation offering referred to any voluntary offering that was presented to the priests, but did not necessarily involve physical lifting. In modern times, these terms are no longer used in religious practices, but their historical significance shows the importance of giving to God in ancient cultures.
