1) COOKED AND MIXED WINE
(a) (Beraisa): Cooked wine and Aluntis (a drink in which wine
is mixed) of Nochrim is forbidden;
2) EXPOSED WATER AND FOODS
1. We permit Aluntis of a Nochri in its original state
(Rashi - he bought it from a Yisrael, because the
wine was mixed before the Nochri got it; Tosfos -
the other ingredients, we are not concerned that the
Nochri added wine).
(b) Question: What is Aluntis?
(c) Answer (Beraisa): We may make Anomalin on Shabbos, not
1. Anomalin is wine, honey and peppers; Aluntis is old
wine, clear water and balsam oil, a cure to help one
cool off after a hot bath.
(d) (Rabah and Rav Yosef): We are not concerned if mixed wine
was exposed (lest a snake drank from it and emitted
poison in it); we are not concerned that a Nochri would

put in front of them; Avlet was careful not to touch it.
1. Shmuel: We are not concerned for Nisuch of cooked
wine, you may touch it.
(k) Cooked wine of R. Chiya's slave was exposed; he told her

him. A snake was approaching; Rabah's servant added
a little water to the wine, and the snake turned
(n) Answer: Snakes will risk their lives (by drinking in
front of people) for unmixed wine, not for mixed wine.
(o) Question: Is it really true that snakes do not risk their
lives from mixed wine?!
1. R. Yanai was drinking mixed wine; some was left, he
covered it. He saw a snake add water to it and drink
(p) Answer: A snake will risk its life for wine it mixed
itself, not for wine that others mixed.
(q) Objection (Rav Ashi): Exposed wine is dangerous, we
cannot rely on these poor answers! (Rather, we are always
concerned for exposure of mixed wine.)
(r) Rava: The Halachah is, we are concerned for exposure and
Nisuch of mixed wine, we are not concerned for exposure
and Nisuch of cooked wine.
(a) Water of R. Chilkiyah bar Tuvi's servant was exposed; he
was sleeping right by it.
1. R. Chilkiyah: Snakes are afraid of people that are
(b) Rav would not drink water in a Nochri's house, for they
are not careful enough about exposure; he would in a
(Yisraelis) widow's house - (even if she does not know
the laws), she conducts as she did when in her husband's
lifetime. (Me'iri - Rav (and Shmuel) do not forbid
drinking by others, they were merely stringent on
2. This is only by day, at night they are not afraid.
3. Rejection: This is wrong - we do not say that snakes
are afraid of sleeping people, not by day nor by
(c) Version #1: Shmuel would not drink water in a (Yisraelis)
widow's house, with no husband to fear, she is not
careful enough about exposure;
1. He would drink water in a Nochri's house - even
though they are not concerned enough for snakes,
they cover water for cleanliness.
(d) Version #2: Shmuel would not drink water in a widow's
house, nor in a Nochri's house.
(e) (R. Yehoshua ben Levi): For three kinds of wine there is
no concern about exposure: sharp, bitter and sweet:
1. Version #1: Sharp - it is so strong, it can break a
pouch; bitter - and bad; sweet - because the sun
ruined the grapes.
(f) (Reish Lakish): We are not concerned for exposure of
2. Version #2 (Rav Chama): These are good wines! Sharp
- on account of peppers and spices; bitter -
wormwood; sweet - a good drink.
(g) (R. Avahu): Karina is sweet vinegar of Asya.
1. (Rava): In Asya, we are concerned for exposure of
(h) (Rava): Wine that started souring: for three days we are

3. Answer: It is the primary drink there, snakes are
used to it.

concerned for exposure - sometimes, a snake will drink

wine (it has not yet fermented, i.e. grape juice).
(k) Question: How long is it considered Toses?
(l) Answer: For three days.
(m) We are not concerned for exposure of cress; in Bavel,
they are concerned;
1. This is only if it has no vinegar; if it does, this
(n) We are not concerned for exposure of Kutach (a dip made
with moldy bread and whey); in Bavel, they are concerned.
1. (Rav Menashi): If we see holes in it (which may be
from snakes), we are concerned (even in Eretz
(o) (R. Chiya bar Aba): We are not concerned for exposure of
dripping wine this deters snakes);
1. (Rav Ashi): This is only if the drops come one right
(p) (R. Chiya bar Aba): If one detached a fig from a tree and
part remained on the tree, we are not concerned that a
snake bit it on the part left on the tree and poisoned
(q) This is like the following Tana.
1. (Beraisa - R. Eliezer): A person may eat figs and
dates at night (even though he cannot check them for
bite marks), he need not be concerned - "Shomer
Pesa'im Hash-m" (Hash-m guards fools who do not know
to guard themselves).
(a) (Rav Safra): There are three types of venom: venom of a
young snake sinks (to the bottom), of a middle-age snake
goes to the middle, of an old snake stays on top.
(b) Question: This implies that snakes get weaker (their
venom is lighter) as they age!
1. Contradiction (Beraisa): Three things get stronger
with age: fish, snakes and pigs.
(c) Answer: They get stronger, but the venom gets lighter.
(d) Question: Why must he teach that venom of a young snake

people drank from it (and are fine), it is forbidden to
drink from it;
1. A case occurred, a tenth person drank and died.
(f) (Beraisa): A person may not pour exposed water in a
public domain, nor sprinkle it in the house (to keep the
dust from scattering), nor use it to knead mud, nor give
to his or another's animal to drink, nor wash his hands,
feet and face;
2. (R. Yirmeyah): This is because the venom was at the
3. Similarly, if a cut watermelon was exposed, even if
nine people ate from it, it is forbidden to eat from
it; a case occurred, a tenth person ate and died.
(g) Others say, he may only wash places where there are no
cracks (for drops remain there, and the venom will burn
through his skin).
(h) Question: About what do they argue?
(i) Answer: The back of the hand or foot, and cheekbones
(there are no cracks, but the first Tana forbids them).
(j) (Beraisa): He may not give it to his or another's animal
(k) Contradiction (Beraisa): He may give it his own animal to
(l) Answer: The latter Beraisa permits giving it to his cat
(Rashi - the venom will not harm it; Ran - we are only
concerned for a Kosher animal, lest a person will eat it
and be harmed).
(m) Question: He should also be allowed to give it to someone
(n) Answer: This may weaken the cat.
(o) Question: It may also weaken his own cat!
(p) Answer: It will get stronger again.
(q) Question: Also someone else's cat will get stronger
(r) Answer: Perhaps the owner needs to sell it now, and no
one will buy it.
