Eruvin 65B

אי נשפך בביתו כמים ⁠— איכא ברכה, ואי לא ⁠— לא.

This teaches that if wine flows in a person’s house like water, there is a blessing, but if not, there is no blessing.

אמר רבי אילעאי, בשלשה דברים אדם ניכר: בכוסו, ובכיסו ובכעסו. ואמרי ליה אף בשחקו.

R' Elai said: In 3 matters a person’s true character is ascertained; in his cup, i.e., his behavior when he drinks; in his pocket, i.e., his conduct in his financial dealings with other people; and in his anger. And some say: A person also reveals his real nature in his laughter.

אמר רב יהודה אמר רב: ישראל וגוי בפנימית, וישראל בחיצונה. בא מעשה לפני רבי, ואסר, ולפני רבי חייא, ואסר.

The Talmud returns to the topic of eiruvin: Rav Yehuda said that Rav said: It once happened that there were two courtyards, one within the other, with a Jew and a non-Jew living in the inner courtyard, while a single Jew lived in the outer one. The case came before R' Yehuda HaNasi for a decision as to whether carrying in the outer courtyard could be permitted without renting from the non-Jew, and he prohibited it. The case then came before R' Ḥiyya, and he too prohibited it.

יתוב רבה ורב יוסף בשילהי פירקיה דרב ששת, ויתיב רב ששת וקאמר: כמאן אמרה רב לשמעתיה, כרבי מאיר. כרכיש רבה רישיה.

Rabba and Rav Yosef were sitting at the end of Rav Sheshet’s lecture, and Rav Sheshet sat and said: In accordance with whose opinion did Rav say this ruling of his, with regard to the residents of two courtyards? It was in accordance with the opinion of R' Meir, who maintains that a non-Jew renders it prohibited for even a single Jew who resides with him to carry in the courtyard, and therefore it is necessary for the Jew to rent from him. Rabba nodded his head in agreement with this explanation.
