Leviticus 2:8
Bring to the Lord the grain offering made in one of these ways. When it is presented to the priest, he shall take it to the altar. The bringing, the presenting, and the taking to the altar are three separate acts involving the offerer, the priest, and the altar — a three-stage movement that enacts the covenant's mediated structure. The offerer brings what they have made; the priest receives and takes it forward; the altar receives what the priest brings. The offerer cannot bypass the priest and approach the altar directly; the priest cannot receive the offering without presenting it at the altar. The structure of mediation is built into the physical movement of every grain offering.
