Pesachim 111


(a) Resh Lakish strongly advises against doing any one of four things because of Ru'ach Ra'ah (demons): To defecate between a date-palm and a wall, to pass between two palm-trees, to drink borrowed water or to pass over water that was poured out.
1. How close must the palm-tree be to the wall for it to be dangerous to defecate between a date-palm and a wall?
2. Why does this not apply if there is an alternative route?
(b) To pass between two palm-trees: Under which condition is it safe to do this?

(c) To drink borrowed water: Does it make any difference ...

  1. ... who borrowed the water?
  2. ... where one drinks it?
  3. ... whether he borrowed water, wine or beer?
(d) To pass over water that was poured out: If one scatters dust over it or pours spittle into it, it becomes safe to do so.
One of two things that happen to it also render it safe to do so.
  1. What are they? Does it make any difference whether one ...
  2. ... walks over it or rides a donkey?
  3. ... walks bare-footed or wears shoes?
(a) What happened to that man who walked over water that was poured out, in spite of the fact that he was wearing shoes?

(b) But did we not learn earlier that the danger only exists when one walks bare-footed?

(a) What do a dog (or two), a date-palm (or two) and a woman (or two) have in common?

(b) Which other two creatures do some opinions include in this list?

(c) If a woman who is at the *beginning* of her Nidus-period walks between two men, she is likely to cause one of them to die.
What would happen if she was at the *end* of her Nidus?

(d) Should someone find himself in any of the above situations, he should recite one of two Pesukim said by Bil'am.
What is special about these two Pesukim?

(a) If two women are sitting by the crossroads on opposite sides of the street, facing each other, they are certainly busy casting spells, and one is well-advised to take a different route. What should one do if this is not possible and one is walking with a partner?

(b) When should one recite the Pasuk in Tehilim "Shofech Buz Al Nedivim" ... ?

(c) The Pasuk "Gam Ki Eilech be'Gei Tzalmaves Lo Ira Ra Ki Ata Imadi" (ibid) refers to someone who walks in the shade of single date-palm or in the shadows cast by the wall when the moon is shining. How does the Gemara prove from a Beraisa that warns against sleeping under a date-palm in a courtyard, that this applies even if the shadow of another date-palm falls across it?

(d) Why is it unsafe to walk in the shadows cast by the wall when the moon is shining, and when is it safe to do so?
