Vayikra Dibbura DeNedavah, Chapter 12
1) "And if a meal-offering (baked) on a machavath (griddle) is your offering": We are hereby taught that "machavath" is a vessel. (This has various halachic ramifications.) (It is stated here) "your offering," and, below (Vayikra 2:7), "your offering," for a gezeirah shavah (identity). Just as the offering here requires pouring (of oil) and mixing, so, the offering below. And just as the offering below requires placing oil in the vessel before it (the meal-offering) is processed, so, the offering here.
