Kiddushin 31B

ומביאו לחיי העולם הבא.

and this action brings him to the life of the World-to-Come.

אמר רבי אבהו: כגון אבימי ברי קיים מצות כיבוד. חמשה בני סמיכי הוה ליה לאבימי בחיי אביו, וכי הוה אתא רבי אבהו, קרי אבבא, רהיט ואזיל ופתח ליה ואמר: אין, אין, עד דמטאי התם.

R' Abbahu said: One such as Avimi, my son, properly fulfilled the mitzva of honoring his parents. The Talmud relates: Avimi had 5 sons during his father’s lifetime who were ordained to issue halakhic rulings, and he too was ordained. And yet when R' Abbahu, his father, came and called at the gate to enter, Avimi would himself run and go to open the door for him. And before he arrived there, he would already say: Yes, yes, so that his father would not think that he was being ignored.

יומא חד אמר ליה: אשקיין מיא. אדאייתי ליה נמנם. גחין קאי עליה עד דאיתער. איסתייעא מילתיה ודרש אבימי ״מזמור לאסף״.

One day R' Abbahu said to Avimi his son: Give me water to drink. Before he brought him the water, R' Abbahu dozed off. Avimi bent over and stood over him until his father awoke. The performance of this mitzva aided him, i.e., as a reward God helped him in his studies, and Avimi succeeded in homiletically interpreting the psalm: “A song to Asaph” (Psalms 79).

אמר ליה רב יעקב בר אבוה לאביי: כגון אנא, דעד דאתינא מבי רב אבא מדלי לי כסא ואמא מזגה לי, היכי איעביד? אמר ליה: מאמך קביל, ומאבוך לא תקבל דכיון דבר תורה הוא חלשה דעתיה.

Rav Ya’akov bar Avuh said to Abaye: With regard to one such as I, so beloved by my parents that before I return from the study hall my father brings me a cup and my mother pours for me, how should I act? Is it disrespectful to accept this honor from them? Abaye said to him: Accept it from your mother, but do not accept it from your father, as, since he is a Torah scholar he will be disheartened if his son does not show him the proper level of respect.
