Inference: Talmidim may go to learn Torah without permission of their wives for 30 days. With permission of their wives, it is even for much [time].

Source #1 (R. Shmuel bar Nachman citing R. Yonason): "Va'Yishlachem Levanonah Aseres Alafim ba'Chodesh." (This shows that one may go for a month without permission.)

(R. Avin): Hash-m endeared Peru u'Rvu more than building the Beis ha'Mikdash.

What is the source? "Chodesh Yihyu ba'Levanon u'Shenayim Chadashim b'Veiso" (the men spent more time at home with their wives than they did cutting trees for the Mikdash).

Source #2 (Rav): "Ha'Ba'ah veha'Yotzeis Chodesh b'Chodesh l'Chol Chadshei ha'Shanah." (Also this shows that one may go for a month without permission. We explained this like MAR'EH HA'PANIM.)

Question: Here (the Reisha) you say [that Onah of workers] is once a week, and here (the Seifa) you say [that it is] twice a week!

Answer (Bar Kapara - Beraisa): Workers may go away without permission of their wives for one week. (This answers the question. The Reisha teaches this; it does not discuss Onah. - PNEI MOSHE)

(Mishnah): The Onah said in the Torah.

Some teach that She'er is intimacy, and Onah is food. Some teach that Onah is intimacy, and She'er is food.

The one who says that She'er is intimacy, he learns from "Ish Ish El Kol She'er Besaro." Onah is food - "va'Ya'ancha va'Yar'ivecha";

The one who says that She'er is food, he learns from "va'Yamter Aleihem ke'Afar She'er." Onah is intimacy - "Im Ta'aneh Es Benosai" - this is [denying] intimacy.

R. Eliezer ben Yakov explained "She'erah Kesusah" - the clothing is according to the age. He may not give what is proper for a youth to an old woman, nor what is proper for an old woman to a youth.

"Kesusah v'Onasah" - the clothing is according to the season. He may not give what is proper for summer in winter, nor what is proper for winter in summer.

Question: What is [R. Eliezer ben Yakov's] source for food? (He does not expound She'erah or Onasah to obligate feeding her.)

Answer: If matters not essential for life (clothing) he may not withhold from her, matters essential for life, all the more so!

Question: What is his source for Onah (of intimacy? He does not learn this from She'erah or Onasah.)

Answer: If matters that she did not marry for (i.e. in order to get) them, he may not withhold from her, matters that she married for them, all the more so!

From the gift that Yakov Avinu sent to Esav, R. Eliezer learned [that Onah is according to one's occupation]. He sent (a proportional number of males to females) based on their labor;

"Izim Masayim u'Syashim Esrim" - one [male] for 10 [females]. "Rechelim Masayim v'Eilim Esrim" - one for 10 (goats and sheep do not work);

"Gemalim Meinikos u'Vneihem Sheloshim" - R. Berachiyah said, since [a camel] is modest in its Bi'ah (they face away from each other), the Torah did not publicize (explicitly say that he sent males. There is only a hint - we read u'Vneihem like u'Voneihem, i.e. males that impregnate females. Since camels do heavy work, he sent a male for each female];

"Paros Arba'im u'Farim Asarah" - one [male] for four [females], for they toil in work (during the plowing season, but not the entire year);

"Asonos Esrim va'Yarim Asarah" - one for two, for they toil in work (they carry burdens the entire year).

Question (R. Yirmeyah): These Chachamim - is it not reasonable to make their law like idle men?! (They do not do physical toil.)

Question (R. Yirmeyah): These Chachamim - is it not reasonable to make their law like sailors?! They exert themselves more [than sailors]!)

(Rav): [A Chacham's wife] eats with him from Shabbos night to Shabbos night (i.e. on Shabbos night, but not in between) - this is a euphemism [for intimacy].
