Tohoros 7:6-7

Tohoros 7:6

If tax collectors entered a house, the house is unclean. If a non-Jew was with them, they’re believed if they say that they didn’t enter but not if they say that they didn’t touch anything. If thieves entered a house, only the part where they walked is unclean. They only render food, liquids and open earthenware vessels unclean; couches, chairs and earthenware vessels with tight-fitting lids remain clean. If a non-Jew or a woman was with them, everything is rendered unclean.

Tohoros 7:7

If a person left his clothes in the bathhouse attendant’s lockers, Rabbi Elazar ben Azariah says that they’re clean but the Sages say they’re only clean if the attendant gives him the key or the seal, or if he left some recognizable sign on them. If a person left his utensils from one year’s wine-pressing to the next, they remain clean; if he left them with a Yisroel (an Israelite, as opposed to a kohein or a Levi), the utensils aren’t clean unless the watchman tells him that he watched them carefully.
