 Noting the words "shall eat and be satisfied" in the Sifre taught that one had to give the poor and the Levite enough to satisfy them.The Mishnah thus taught that they did not give the poor person at the threshing floor less than a half a "kav" (the equivalent in volume of 12 eggs, or roughly a liter) of wheat or a "kav" (roughly two liters) of barley.The Mishnah taught that they did not give the poor person wandering from place to place less than a loaf of bread.
