(Mishnah): A man may not go out [on Shabbos] with a sword, bow, shield, Alah (club) or spear. If he did, he is Chayav Chatas;

R. Liezer says, these are Tachshitim for him;

Chachamim say, they are only a disgrace for him - "v'Chitsu Charvosam l'Itim... Lo Yisa Goy El Goy Cherev v'Lo Yilmedu Od Milchamah.''

A Biris is Tahor, and one may go out with it. Kevalim are Teme'im, and one may not go out with them. (These will be explained.)

(Gemara): "Va'Chamushim Alu Vnei Yisrael me'Eretz Mitzrayim'' teaches that they were armed with five kinds of weapons (those listed in our Mishnah).

Question: What is Alah?

Answer: Since R. Yakov bar Sisi taught in the name of R. Yosah "from when does one tithe the granary? From when they uproot the Alah (the spike inserted in the ground, around which they make a granary)'', this teaches that [Alah] is like a spike (PNEI MOSHE).

What is R. Eliezer's source [that they are Tachshitim]? "Chagor Charbecha Al Yerech Gibor Hodcha va'Hadarecha.''

What is Rabanan's source? "V'Chitsu Charvosam l'Itim'' - (they will beat their swords to become) Itin (shovels), "va'Chanisoseihem l'Mazmeros'' - (their spears) to shearing scissors.
