Eruvin 54A

בטשה ביה, אמרה ליה: לא כך כתוב ״ערוכה בכל ושמורה״, אם ערוכה ברמ״ח אברים שלך ⁠— משתמרת, ואם לאו ⁠— אינה משתמרת. תנא: תלמיד אחד היה לרבי אליעזר שהיה שונה בלחש, לאחר שלש שנים שכח תלמודו.

She kicked him and said to him: Isn’t it written as follows: “Ordered in all things and secure” (ii Samuel 23:5), which indicates that if the Torah is ordered in your 248 limbs, i.e., if you exert your entire body in studying it, it will be secure, and if not, it will not be secure. The Talmud relates that it was similarly taught in a baraita: R' Eliezer had a student who would study quietly, and after 3 years he forgot his studies.

תנא, תלמיד אחד היה לו לרבי אליעזר שנתחייב בשריפה למקום. אמרו: הניחו לו אדם גדול שמש.

Incidental to the story cited above involving a student of R' Eliezer, the Talmud cites the following episode: It was taught in a baraita: R' Eliezer had a student who was liable for the punishment of death by burning, for his sins against God, but the Rabbis said: Let him alone and do not punish him as he deserves, because he served a great person.

אמר ליה שמואל לרב יהודה: שיננא, פתח פומיך קרי, פתח פומיך תני, כי היכי דתתקיים ביך ותוריך חיי, שנאמר: ״כי חיים הם למצאיהם ולכל בשרו מרפא״, אל תקרי ״למצאיהם״ אלא ״למוציאיהם בפה״.

The Talmud cites instructions issued by Shmuel that are similar to those of Berurya. Shmuel said to Rav Yehuda: Keen scholar [shinnana], open your mouth and read from the Torah, open your mouth and study the Talmud, in order that your studies should endure in you and that you should live a long life, as it is stated: “For they are life to those who find them, and health to all their flesh” (Proverbs 4:22). Do not read: “To those who find them [lemotzeihem],” but rather “to those who express them [lemotzi’eihem],” with their mouth.

אמר ליה שמואל לרב יהודה: שיננא, חטוף ואכול חטוף ואישתי, דעלמא דאזלינן מיניה כהלולא דמי.

The Talmud cites additional instructions issued by Shmuel: Shmuel said to Rav Yehuda, his beloved student: Keen scholar, grab and eat, grab and drink, as the world from which we are departing is like a wedding feast, whose joy is only temporary, and one who does not take pleasure in it now will not be able to do so in the future.
