Translation:Mishnah/Seder Moed/Tractate Shabbat/Chapter 22/3

Mishnah 3
 A man may break open a cask, to eat dry figs therefrom; provided, he does not intend using the cask afterwards as a vessel. He must not pierce the bunghole of a cask, such is the decree of R. Jehudah (or R. Jose); the sages permit this to be done. And one must not bore a hole in the side of it; but if it was already perforated, he must not fill it up with wax, because he would smoothen the wax thereby. Said R. Jehudah: "Such a case was brought before R. Johanan ben Sachai, at Arab, and he observed: 'I doubt whether that act does not involve liability to bring a sin-offering.'"
