(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?

5)

(a) What happens to someone who ...

1. ... defecates on a date-palm that has been cut down?
2. ... lays his head on it?

(b) What will happen to someone who steps over the stump of a date-palm ...

1. ... if it is later chopped down?
2. ... if it subsequently dies?

(c) What would one have to do to ensure one's safety in such a case?

(a) Five shades are dangerous because they are frequented by the demons. These include the shade of a lone date-palm, a caper-bush and a willow - tree. Some add a sixth shade of something that is not a tree at all.
What is it?

(b) Which two factors determine what type of wood is dangerous?

(c) The one exception is a tree called 'K'ra Masa', whose wood is hard, but whose shade is not dangerous.
What did a she-demon tell her son regarding this tree?

(a) What do Ruchi, Shida and Rishpi have in common?

(b) Why do we need to know this, and the fact that a sorb tree that is close to the town contains at least sixty Sheidim?

(c) The demon of the caper-bush has no eyes.
Why is it useful to know that?

(a) What did the demons mean when they said about the Talmid-Chacham who did not know that at least sixty demons frequent a sorb-tree 'Sudra de'Mar ke'Tzurba me'Rabbanan. Bedikna Bei de'Lo Yada Baruch'?

(b) The person in danger was the 'Bar Kasha de'Masa'.
What does that mean?

(c) How did that story end? Did the demons prevail or not?

(a) What is the difference between Ketev-Meriri and Ketev-Yashud- Tzaharayim?

(b) If the former resembles a jar of Kutach with a ladle stirring it, what does the latter look like?

(c) Why did Abaye switch Rav Papa to his left-hand side when he saw a Ketev- Yashud-Tzaharayim coming towards him on the left?

(d) During a period of sixteen days each year Ketev-Yashud-Tzaharayim is common.
When is that, and what happens afterwards?

(a) Where else, besides by the shade of the Chatzav-tree that has not yet grown to the height of one Amah, is one likely to find the Ketev-Yashud- Tzaharayim?

(b) Where is his main haunt?

(a) Rav Yosef lists three things that cause blindness: someone who combs his hair when it is dry and someone who drinks wine that drips from the barrel. What is the third?

(b) What happens to someone who suspends his bread in a basket in the house?

(c) Does this also happen to someone who suspends meat or fish?

(a) What two other things cause poverty?

(b) On which two nights do the demons operate?

(c) Naval is the name of the demon in charge of poverty.
Which houses does he *not* frequent?

(d) Who is Nakid?

(a) What happens to someone who drinks water in a plate?

(b) And what happens to someone who does not wash his hands after ...

1. ... eating cress?
2. ... letting blood from the shoulders?
3. ... cutting his hair?
4. ... cutting his nails?

(c) What unusual feature do all of these fears have in common?
