“A wave offering before the LORD”
he shall bring the fat, together with the breast, and wave the breast as a wave offering before the LORD. (Leviticus 7:30 BSB)
What it sounds like today
An odd instruction to wave a piece of meat around.
The cultural key
'Wave offering' names a specific liturgical gesture, not random motion. The Hebrew tenufah refers to an elevating and extending movement: the priest took the designated portion (here the breast of the fellowship offering) and ceremonially lifted and moved it out toward the altar and back, or raised it up and set it down, presenting it before the LORD. The symbolism is a transaction made visible: the worshiper's gift is formally handed over to God (moved toward the altar), and then God grants a portion back to the priests to eat (moved back). It enacts the whole logic of sacrifice, offering to God and receiving from God, in a single gesture, and it assigns the priests their living from the altar. A modern reader pictures someone absurdly waving meat; the first hearers saw a solemn ritual of presenting a gift to God and receiving His portion in return.
Recovered meaning
The 'wave offering' (tenufah) was a ceremonial gesture of lifting and presenting the portion toward the altar and back, dramatizing the gift's transfer to God and God's return of a share to the priests. It is ritual presentation, not aimless waving.
