Variantly: "You shall not plow": This tells me only of plowing. Whence do I derive (the same for) threshing and sitting in a wagon (to which they are attached) and going out and directing (them)? It is, therefore, written "together" — in any event. R. Meir exempts sitting in a wagon, (for in that instance he is not doing anything).
Variantly: "together": to exclude a mule. Variantly: "together": to exclude tying a horse to a side or the back of a wagon (to which oxen are hitched).
(Devarim 22:11) "You shall not wear shatnez (a mixture), wool and linen together": I might think, he must not wear shorn wool and flax stalks; it is, therefore, written "shatnez," something that is fulled, spun, and twisted (or woven) (shua, tavi, venoz [acronym of "shatnez"]). R. Shimon b. Elazar says: (He who wears shatnez) is perverse ("naloz") and estranges ("meiliz") his Father in heaven [play on "noz" (woven)]. Felt cloaks (of mixed materials) are forbidden as kilayim (intermixtures). Even though they do not come under "weaving," they do come under "spinning."
