dear rabbi
I am learning megillah 8b i wanted to know if a mezorah will touch a earthen vessel with a long stick will it become tumah or is this law only by tuma of a zav?
rashi sounds like only a zav
menachem friederwitzer, Israel
Only by Zav (and Zavah, Nidah, and Yoledes) -- and not by Metzora -- is Tum'ah conveyed in your case of a Tamei moving a Tahor item.
The source is the Mishnah in Zavim 5:6, and the Mefarshim there --Tosfos Yom Tov (DH Echad ha'Meisit), Tiferes Yisrael (Yachin 52), Mishnah Achrona DH v'Echad ha'Nosei. See also Tosfos in Pesahim 67b, DH she'Ken.
(A Tahor person moving a Tamei, though, is different.)
All the best,
