וּמְחִ֣י קָֽבָלּ֔וֹ יִתֵּ֖ן בְּחֹֽמוֹתָ֑יִךְ וּמִ֨גְדְּלֹתַ֔יִךְ יִתֹּ֖ץ בְּחַרְבוֹתָֽיו׃
Les coups de son bélier, il les assénera sur tes remparts, et tes tours, il les brisera par ses armes.
Mishnah Kelim
The sheath of a sword, a knife or a dagger, the case for scissors, or shears or a razor, the case of make-up and the make-up box, the stylus case, the compass case, the tablet case, the case for a board, a quiver and a javelin case all these are susceptible to uncleanness. The case for a double flute is susceptible to uncleanness if the instrument is put in from above, but if it is put in from the side it is clean. A case for flutes Rabbi Judah says it is clean because these are put in from the side. The covering of a club, a bow or a spear is clean. This is the general rule: that which serves as a case is susceptible to uncleanness, but that which is merely a covering is clean.
