Reference: Tosfos already explained this in 'Eilu Ovrin' (above, Daf 49:).

Implied Question: In Perek Eilu Ovrin (ibid.) Rav Papa declared that had he not married a Kohenes, he would not have become wealthy?

Answer: Both reasons attributed to his wealth.

Implied Question: When the Gemara says in the second Perek of Beitzah (Daf 16:) that when someone cuts down on the expenses for Shabbos and Yom-Tov, then he receives less Divine Assistance (See Maharsha)?

Answer: It is speaking about his own money, when he has.

Clarification: He refrains from drinking the during the meal in order to have wine for Havdalah.

Question: It is specifically the night Kidush that takes precedence over Kibud Yom, but not Havdalah (See Maharsha).

Answer: Mori ha'Ri explains that the Gemara calls Kidush Yom 'Kibud Yom' (i.e. the 'Kibud Yom' mentioned on Daf 105: really refers to Kidush Yom).

Support: And so the Yerushalmi says in Perek Sheloshah she'Achlu - 'Rebbi Yossi in the name of Rebbi Ya'akov b'Rebbi Ada says "What is Kibud Yom - Borei P'ri ha'Gafen" ' (with reference to Kidush.

Question: In 'Eilu Metzi'os' (Bavas Metzi'a, Daf 32: & 33.) the Gemara says that 'If someone has the option of unloading on behalf of a friend, and loading on behalf of a person he hates, he should perform the latter, since it is a Mitzvah to overcome one's Yeitzer ha'Ra'.

Question (cont.): But how can one be obligated to overcome one's Yeitzer ha'Ra when, according to our Sugya, the owner of the donkey sinned, and it is a Mitzvah to hate him?

Answer: Since he hates the sinner, the sinner hates him - as the Pasuk writes in Mishlei (27) "Just as the water shows one the reflection of one's face, so too, is the heart of one man to the other".

Answer (concl.): And this leads to a genuine hatred, which is subject to 'overcoming one's Yeitzer.

Clarification: This speaks specifically where this is the result of his 'lack of effort', because he does not indulge in the Mitzvah of Piryah ve'Rivya, similar to the other cases (mentioned in the Beraisa).

Consequently (Explanation #1): And 'someone who does not wear Tefilin on his head and on his arm and Tzitzis on his garment' speaks where he owns Tefilin but fails to don them.

Explanation #2: Alternatively, it speaks even where he does not have, and he is obligated to try and obtain them in order to fulfil the Mitzvah ...

Proof: Like we find in Sotah (Daf 14.) regarding Moshe, who longed to enter Eretz Yisrael in order to fulfil the Mitzvos connected with it.

Implied Question: And when the Gemara says (in Shabbos, Daf 49.) that 'Tefilin require a clean body like Elisha (Ba'al Kenafayim) ...

Answer: This refers to not making a smell or sleeping whilst wearing them ...

Answer (cont.): And whilst reciting Keri'as Sh'ma, which one recites in order to take upon oneself a full-fledged Malchus Shamayim (See B'rachos 15.), it is easy to fulfil.

Question: The Beraisa in Perek ha'Meivi (Beitzah, Daf 32.) lists three people whose lives are not worth living - Someone who relies entirely on others for his Parnasah, someone who is under his wife's jurisdiction and someone whose body is racked by suffering.

Question (cont.): Why does the Gemara here not include them in its list?

Answer: The Gemara here is is speaking exclusively about things that are the result of a person's own actions ...

Proof: Since the previous Gemara too, is speaking about that, when it says that 'Hashem likes three kinds of people - someone who does not get angry ... '.
