Mishnah/Seder Nashim/Tractate Sotah/Chapter 2/1
She brings the Minchah offering in an egyptian vessel, and it is put in her hands in order to tire her. All the Minchah offerings begin and end in service vessels, and this, begins in an Egyptian vessel and ends in a service vessel. All of the Minchah offerings require oil and frankincense, and this does not require oil and not frankincense. All the Minchah offerings consists of wheat, and this consists of barley. The Minchah offering of the omer, even though it consists of barley, what she brings consists of sifted flour; and this consists of unsifted flour. Raban Gamliel says: Like she did the doings of an animal, so too her sacrifice is the food of an animal.
