English: It is said here “your offering” and of the marcheshes minchah “your offering” — just as there oil is put in the vessel, so here oil is put in the vessel.
Gezerah shavah of korbanecha — the oil is placed in the vessel before mixing for both forms.
Before mixing, oil is placed in the vessel for a machavas minchah as for a marcheshes. The gezerah shavah drawn from the shared word “your offering” teaches that the initial placement of oil in the vessel applies equally to the flat-pan offering.
