What about someone like Mr. Feival Flatbroak who is too poor to even afford a bird? He can still fulfill the Mitzvah of Korbanos by offering a sacrifice of dough made of flour, oil, and spices. The dough can be raw, fried, or baked, as long as it doesn’t rise. This type of Olah is called Minchah, which means “a gift.”
Here’s another Shazak Scenario:
Mr. Flatbroak gives the dough to the Kohen. Now comes the hard part, called kemitza. It’s the Kohen’s job and takes much practice to get right. The Kohen scoops up as much flour as possible with his 3 middle fingers. He brushes off any excess flour with his thumb and pinky. Then, the Kohen sprinkles salt and spices on it, and burns it on the Mizbei’ach. The remaining flour is baked and eaten by the Kohanim in the courtyard of the Mishkan.
This Minchah offering by Mr. Flatbroak, or any poor person for that matter, is extremely precious to HaShem. Let’s consider this: Our wealthy Mr. Goldbucks may not have thought twice about buying a bull for a Korban, and certainly a handful of flour is no big deal for him. But to Mr. Flatbroak, every penny counts. After all, he is flat broke! Still, he does everything possible in order to bring his Korban Minchah.
To HaShem, the humble Minchah is His favorite, because these poor people sacrificed their own needs in order to bring it. Perhaps Mr. Flatbroak even skipped some meals so he could afford to bring this Korban!
That is why the Pasuk says, “If a Nefesh brings a Korban Minchah,” because it is as if the poor person has offered his nefesh – his very own life – by bringing his Korban!
