Pesachim 113A

גזייתא נינהו, דשמטי סוסיא ואתו דברי להו.

are found on the paths [gazyata] near the city, as horses belonging to the demons flee along those paths, and the demons come to lead them away. Generally, however, demons do not enter inhabited places.

(ואמר ליה) רב לרב אסי: לא תדור במתא דלא צניף בה סוסיא ולא נבח בה כלבא. ואל תדור בעיר דריש מתא אסיא, ולא תנסיב תרתי. אי נסבת תרתי ⁠— נסיב תלת.

And Rav said to Rav Asi: Do not live in a city where horses do not neigh and where dogs do not bark, as these animals provide security and protection. And do not live in a city where the mayor is a doctor, as he will be too busy working to govern properly. And do not marry two women, as they will likely join forces against you. And if you do marry two, marry a third as well. If two of your wives plot against you, the third will inform you of their plans.

אמר ליה רב לרב כהנא: הפוך בנבילתא ולא תיפוך במילי. פשוט נבילתא בשוקא ושקיל אגרא, ולא תימא ״כהנא אנא, וגברא רבא אנא, וסניא בי מלתא״. סלקת לאיגרא ⁠— שירותך בהדך. מאה קרי במתא בזוזא ⁠— תותי כנפיך ניהוו.

Rav said to Rav Kahana: It is better for one to turn over a carcass than to turn over his word, i.e., to break his promise. Rav further said: Skin a carcass in the market and take payment, but do not say: I am a priest, or: I am a great man, and this matter disgusts me. It is preferable for one to work, even in menial labor, than to be dependent on others. Rav also advised Rav Kahana: If you ascend to the roof, carry your food with you. One should always carry his sustenance with him, even if he goes only on a short trip. If 100 pumpkins in the city cost a zuz, place them carefully under the corners of your clothes. Treat food respectfully even if it is inexpensive.
