Pesachim 40


(a) Why is it forbidden to place more than one wheat-kernel at a time into boiling water?

(b) Why did Abaye forbid scorching two wheat-kernels together?

(c) On what grounds did Rava disagree with him?

(d) So what will be the Din according to Rava?

(a) Abaye retracted, but not for the reason given by Rava.
Why then, did he retract?

(b) How do we know that that is what he holds?

(a) May one make Lesisah (soak in water) with barley on Pesach? At which stage does the barley subsequently become forbidden?

(b) Shmuel rules like the Rabbanan of Rebbi Yossi.
What solution does Rebbi Yossi offer?

(c) Shmuel understands 'split' literally;
How does Mar Ukva explain it?

(d) Some Amora'im forbid Lesisah with wheat too, others permit it.
What advantage and what disadvantage does wheat have over barley in this regard?

(a) Rava finally permits Lesisah by wheat from the Beraisa 'Yotz'in be'Pas Neki'ah ve'Hadra'ah'.
What is Rava's proof from there that Lesisah is permitted?

(b) 'ha'Kemachin ve'ha'Siltos shel Nochrim shel Kefarim Tehorim'.
Why is that?

(c) What Kashya does Rav Papa ask on Rava from here?

(d) What is the answer?

(a) Rav Papa upset that he did not ask Rava from Shmuel? What did Shmuel say regarding making Lesisah on Menachos, and what should he have asked Rava from there?

(b) How does Rava then prove from the Pasuk in Bo "u'Shemartem es ha'Matzos" that it is even a *Mitzvah* to make Lesisah on the Matzos shel Mitzvah?

(c) What does Rav Huna say about gentile doughs, and how does Rava prove his point from there?

(d) How does the Gemara reject his proof?

(a) What did Rava instruct the harvesters to do when they arranged the sheaves?

(b) What does this prove?

(c) And what did Mar B'rei de'Ravina's mother do for her son in this regard?

Answers to questions



(a) Rava permitted selling a boat-load of wheat that sank in the River Chishta to gentiles.
What problem did Rabah bar Liva'i have with that?

(b) On what grounds is it permitted to use a garment which contains unmarked Kil'ayim as shrouds for a dead person?

(c) How did Rava subsequently permit the disposal of the boat-load of wheat?

(a) What is Melilah, and how does the Tana Kama permit its performance on Pesach?

(b) The Yesh Omrim who permit Melilah in any order is Rebbi Yehudah.
What does Rebbi Yehudah say (with regard to a K'li Sheni on Shabbos) that causes us to say this?

(c) Why can the Yesh Omrim not be Rebbi Yossi, who says in a Beraisa that vinegar causes dough to freeze, and prevents it from rising?

(d) Ula forbids Melilah in all cases.
On what basis is he so strict?

9) Some say that Rava added dried flour to his cooked dishes on Pesach.
Does this contradict his strong objection to Rav Papi, who permitted the bakers of the Resh Gelusa to do the very same thing?


(a) What should one do after inadvertently adding flour to mustard on Pesach ...
  1. ... according to the Tana Kama?
  2. ... according to Rebbi Meir?
(b) The Torah writes in Bo "u'Vashel Mevushal ba'Mayim".
May one cook the Korban Pesach in fruit-juice or in any other liquid besides water?

(c) May one anoint the flesh of the Korban Pesach whilst it is being roasted, or dip it into liquids whilst it is being eaten?

11) What does one do with the water that the baker used to cool his hands during the baking of the Matzos?
