Today's daf is sponsored by Rabbi Art Gould in loving memory of his beloved bride and best friend of 50 years, Carol Joy Robinson, Karina Gola bat Huddah v’Yehuda Tzvi, on the occasion of her first yahrzeit. "You will be in my heart forever." 

There are two more attempts to prove that tza'ar ba'alei chayim is a rabbinic law, but they are rejected. Within what distance from the animal is one obligated to help load/unload? What is the order of precedence in dealing with people's lost items between oneself, one's father, and one's rabbi? What is the definition of 'one's rabbi'? Is it better to learn Torah, Mishna, or Gemara? What are the dangers of learning Mishna without learning Gemara? What are the dangers of learning Gemara without learning Mishna? If one is watching another's item (an animal or vessels) and is not getting paid (shomer chinam), and the item is stolen, the shomer can take an oath and is exempt. If they find the thief and retrieve the item, the thief pays the double payment to the original owner. But if the shomer decides to pay for the stolen item, the thief will pay the double payment to the shomer. Why was it necessary to mention both an animal and vessels?
