1)

(a) Rav Huna states that one is permitted to write Tefilin on the skin of a Kasher bird.
Why might we have thought otherwise?

(b) Why is it, in fact, permitted?

(c) What do we learn from the Pasuk in Vayikra "ve'Shisa Oso bi'Chenafav"?

(d) Some ask the Kashya that, if the bird's skin *is* considered skin, how could the Torah allow it to be brought on the Mizbei'ach (since the skin of Korbanos is *not* permitted on the Mizbei'ach)?

Others ask that, if it is *not* considered skin, then why would the Torah find it necessary to include it? Why would we have thought *not* to bring it together with the flesh of the bird?
How does the Gemara answer each Kashya?

Note: the Gemara is not concerned with the feathers, even though they are still attached to the bird when it is brought on the Mizbei'ach - see Tosfos D.H. 've'I'.

(a) What do we learn from the Mishnah in Kelim: 'Atzmos ha'Dag ve'Oro, Matzilin be'Ohel ha'Mes'?

(b) Why is that?

(c) Then why do we need Eliyahu to help us resolve the Sha'aleh whether Tefilin may be written on the skin of a Tahor fish?

(d) Why can Eliyahu not simply reveal the Halachah to us?

(a) How did Shmuel read the signs, when he saw the River Malka, which flowed from Eretz Yisrael to Bavel, looking turbid and bringing up high waves of black water?

(b) What was Karna expected to do when Shmuel told him 'Zil Tehi Bei be'Kankanei'?

(c) He asked him three questions. The first question he asked him was: From where do we know that Tefilin must be written on the skin of a Kasher animal?
What did Rav answer?

(d) To the second question, he answered with the Pasuk in Melachim 2: "va'Yir'u Mo'av Mineged es ha'Mayim ke'Dam".
What was Karna's question, and what were its ramifications?

(a) The third question concerned the Mitzvah of B'ris Milah:
How does Rav derive (from Orlah) that the Mitzvah of Milah is performed on the Ever ha'Milah?

(b) The Torah also writes "Orlas" by the heart and by the tongue, so how do we know not to learn the Gezeirah Shavah from there?

(c) Rav's opinion is also that of the Tana, Rebbi Yashiyah.
From where does Rebbi Nasan derive it?

(d) What was Rav's reaction to Karna's welcome?

(e) Shmuel took him to his house.
What did Shmuel do that caused Rav to curse him that he should have no children?

(a) May one write Tefilin on the skin of ...

1. ... a Kasher Chayah
2. ... an animal which is a Neveilah or a Tereifah?

(b) What does 've'Nikrachos be'Sa'aran, ve'Nitfaros be'Gidan' mean, and what is the source for this?

(c) What do we learn from the Pasuk in Sh'mos "Lema'an Tihye Toras Hashem be'Ficha".

(d) Then why may they be written on Neveilos and Tereifos?

6)

(a) The Tana Kama prohibits the preparation of Hilmi on Shabbos, but permits Mei Melach.
What is the difference?

(b) What purpose does such strong salt-water serve, and why did the Chachamim forbid its preparation on Shabbos?

(c) What does Rebbi Yossi hold in this regard, and what is his reason?
According to him, which kind of salt-water *is* permitted?

(d) Mei Melach Azin is prohibited on Shabbos.
What is 'Mei Melach Azin'? How strong is it, and what purpose does it serve?

(a) Rav Yehudah bar Chaviva quotes a Beraisa which forbids salting a radish or an egg on Shabbos.
What is Abaye quoted as saying?

(b) Initially, Rav Nachman used to salt radishes.
Why?

(c) What made him change his mind? Did he then stop salting them altogether?

(d) What do an Esrog, a radish and an egg have in common?

(a) How many people have drowned in the Yam-ha'Melach?

(b) Why did Rav Dimi mention only people? Does this mean that beams *did* sink there?

(c) One is permitted to swim in the Salt-Sea, but not to 'open and close the eyes', when its water is applied as a cure.
Why the difference?

(a) One is forbidden to place both wine and 'Rok Tapal' *into* the eye.
What is the Din with regard to placing either of them *above* the eye? Why the difference?

(b) Which of these two Dinim did Shmuel say in the name of his father, and which in the name of Levi?

(a) Shmuel permitted a salve that was soaked on Erev Shabbos, to be applied on Shabbos.
Why?

(b) Did he also permit opening and closing the eyes to assist the salve to enter?

(c) What did Mar Ukva reply, when Rebbi Yanai asked him to send him some of (the fqamous doctor) Shmuel's eye-salves?

(a) The following hands should be cut-off: 'Yad le'Ayin, Yad le'Chotem, Yad le'Peh, Yad le'Ozen, Yad la'Chasudah, Yad le'Gigis'. What are the following the cause of:

1. Yad le'Ayin?
2. Yad le'Ozen?
3. Yad le'Peh O le'Chotem?

(b) How does one avoid the above problem?

(c) The Beraisa also includes 'Yad le'Peh and Yad le'Amah' in the list. In what way do these two differ from those in the above list?

(d) What three functions do eye-paint serve?
