Moed Katan 10


(a) 'A non-expert is permitted to sew normally'. According to Tana de'Bei Rebbi Yanai, a non-expert constitutes someone who cannot stitch many stitches simultaneously.
How does Rebbi Yossi b'Rebbi Chanina explain it?

(b) 'An expert must be 'Machliv'. According to Rebbi Yochanan, this means wide stitches.
How does Rabah bar Shmuel explain it?

(c) The Tana Kama of our Mishnah says 'Mesargin es ha'Mitos', Rebbi Yossi, 'Memaschin'. Rebbi Yochanan and Chizkiyah argue over this. One of them explains 'Mesargin' to mean one arranges the cords on the bed 'Shesi ve'Areiv'.
What does this mean, and what is then the meaning of 'Memaschin'?

(d) According to the second explanation, 'Mesargin' means stretching the cords one way only ('Shesi').
What does 'Memaschin' then mean?

(a) Rav Tachlifa bar Shaul cites a Beraisa (with reference to the Machlokes between the Tana Kama and Rebbi Yossi) 've'Shavin she'Ein Mafshilin Chavalin Lechatchilah'.
With which of the two above explanations does this create a difficulty?

(b) And on which of the two explanations does Rebbi Meir's statement (in the Mishnah in Keilim) 'ha'Mitah mi'she'Yisrog Bah Sheloshah Batim' create a difficulty?

(c) So how do we amend the two above opinions? In which point do they argue, and in which point do they agree?

(d) How does the opinion which explains 'Memaschin' to mean just to tighten it, explain the 'Yesh Omrim' in the Beraisa, which forbids even 'Memaschin'? On what grounds would Chazal forbid just tightening the cords of a bed on Chol ha'Mo'ed?

(a) One is permitted to build from scratch a Tanur, a Kirayim and a mill. What is the difference between a Tanur and a Kirayim?

(b) Rebbi Yehudah says 'Ein Mechabshin es ha'Reichayim Lechatchilah'. Rav Yehudah interprets 'Mechabshin' as 'Menaker Reichaya'.
What does that mean?

(c) Rav Yechiel interprets it as 'Bas Eina'.
What is 'Bas Eina'?

(a) Rebbi Eliezer, in the Beraisa, permits the construction of an oven, on Chol ha'Mo'ed, provided one does not finish the job.
What do the Chachamim say?

(b) According to Rebbi Yehudah, Rebbi Eliezer differentiates between a new oven and an old one.
What distinction does he make between them?

(c) What does Yesh Omrim say?

(a) In which way does Rebbi Yehudah's opinion by an old oven (according to Rebbi Eliezer) pose a Kashya on Rav Yechiel above (in 3c., who says that Mechabshin means making a hole for the wheat)?

(b) How do we reconcile Rav Yechiel?
