Rashi
שור או חמור AN OX OR AN ASS — This is the law also with respect to all cattle and beasts, because wherever the Torah prescribes something with regard to “ox or ass”, we derive it (the fact that it applies to all cattle and beasts) on the grounds of the verbal similarity of שור in the text in question with שור which occurs in the law prescribing the Sabbath rest, for — with regard to the latter — it is stated, (Exodus 23:12) “that thine ox and thine ass may rest”. Now how is it in the latter case? We know that all cattle and beasts are to be treated in this respect as the “ox”, because in another passage referring to Sabbath (Deuteronomy 5:14) it is expressly said “[thy ox and thy ass] and all thy cattle”! So here, too, all cattle and beasts are to be treated as the ox. The only reason why ox and ass are alone mentioned is to imply: “an ox” — but not a man, “an ass” — but not vessels (Bava Kamma 53b).
