Bava Metzia 91 - May 29, 21 Iyar

If someone rents an animal and muzzles it while it is threshing, they must receive lashes as punishment and also compensate the owner for the food the animal should have eaten while working. The Gemara questions how this can be allowed since it appears to be a double punishment, and the court cannot give one a double punishment for one action. Abaye, Rava and Rav Papa each suggest a possible answer. Rav Papa rules on two unrelated issues - one prohibiting baking bread that is dairy or meat, and another prohibiting putting a male and female animal of different species in the same pen to prevent mating between different species, even though this latter ruling is not explicitly prohibited by the letter of the law. Rav Achdevoi bar Ami raises a difficulty against Rav Papa's second ruling, but this difficulty is resolved. He also brings the same source to question a ruling of Rav Yehuda on animal mating, but it is also resolved. The Mishna discusses the laws regarding a worker eating while on the job, including whether the obligation to allow them to eat is only if they are engaged in work with both hands and legs like an ox who can't be muzzled and works with all fours. If one works with one type of produce, one cannot eat a different type of produce in the field. Even though workers are only permitted by Torah law to eat while actively working, the rabbis permitted them to eat while walking between rows to prevent financial loss for the employer. The Gemara raises a question about whether a worker can eat from the same type of produce in a different area and attempts to answer this from three different rulings in the Mishna, but rejects each suggestion.
