Comentario citado sobre Deuteronómio 5:14

Now, consider: All matters are included in muzzling - that is to say, you are forced to concede that "ox" is not meant specifically, but that all other animals are included in the halakha of muzzling, since we derive [a verbal analogy using the words] "ox" "ox" from [the laws of] Shabbat [Bava Kamma 54b:10]. It is written regarding [the laws of resting one's animals on] Shabbat: "or any of your cattle" [Deuteronomy 5:14]. Since "ox" is not meant specifically, why would the All-Merciful need to write it? Let it have written [instead] "do not thresh with a muzzle."

ושנסקל תרנגול שהרג את הנפש – that perorated the brain of a baby and even though it is written (Exodus 22:28): “When an ox gores [a man or a woman...],” both an ox and cattle, beasts and birds are included, for every place where it says, “ox,” we learn (Deuteronomy 5:14): “[but the seventh day is a sabbath of the LORD your God; you shall not do any work] – you, your son, or your daughter, your male or female slave, your ox or your ass, or any of your cattle…” from [the law of] Shabbat. Just as further on, the same law applies to all cattle, beasts and birds, even here the same law applies to all cattle, beasts and birds.

Unreines mit Reinem und Reines mit Unreinem darf man nicht zusammenpflügen. Natürlich sind hier zweierlei Arten gemeint. Obgleich in der Bibel nur von Ochs und Esel die Rede ist, so wurden dennoch nach der Analogie von שבת (Deut. 5,14) alle Tiere darunter verstanden.
