[If] an idolater was found standing beside a wine cistern: if he has a lien (lit., a loan) upon it, it is prohibited; if he does not have a lien upon it, it is permitted. [If] he fell into the cistern and came out, or he measured it with a reed, [or] he flicked out a hornet with the reed, or if he was tapping on top of a foaming barrel —- all these [cases] were actual incidents, and they said it should be sold. R’ Shimon, however, permits. [If] he took a barrel and threw it in his anger into the cistern, this was [once] an incident and they declared [it] fit.
