1) WHO COVERS THE BLOOD?
(a) (Mishnah): If a man slaughtered and did not cover the
blood; one who sees this must cover the blood.
2) WHEN THE MITZVAH IS FINISHED
(b) If one covered the blood and it became exposed, he need
not cover it again;
1. If the wind (blew dirt and) covered it, he must
(c) (Gemara - Beraisa): "V'Shafach...v'Chisahu" - the one who
spills the blood (slaughters) must cover it;
1. Question: How do we know that if he did not cover
it, an onlooker is obligated?
(d) (Beraisa): "V'Shafach...v'Chisahu" - he must cover with
what he spilled, i.e. his hand.
2. Answer: "Say to Benei Yisrael" - they are all
1. He may not cover with his foot, lest Mitzvos would
be disgraceful in his eyes.
(e) (Beraisa): "V'Shafach...v'Chisahu" - the one who spills
must cover it;
1. A case occurred, Reuven covered the blood of what
Shimon slaughtered; R. Gamliel made Reuven pay
Shimon 10 gold coins.
2. Question: Is this for stealing the Mitzvah, or for
depriving him of the blessing?
i. From here we can learn the fine for blessing
over a meal (to exempt the others, when someone
else should have blessed.)
3. Answer: We can learn from the following story.
ii. Birkas ha'Mazon is only one Mitzvah, but it is
4. A Tzeduki (heretic): Different powers created the
mountains and the wind - "The One Who formed
mountains, and the One Who created wind".
5. Rebbi: The end of the verse says "Hash-m Tzevakos
Shemo" (He created both.)
6. The Tzeduki requested three days to respond; Rebbi
fasted those three days. When Rebbi was about to end
his fast, another Tzeduki informed him that the
first one killed himself.
7. Rebbi invited this man to eat; he offered him 40
gold pieces if he will decline to drink the wine
over which they will say Birkas ha'Mazon. (Ben
Yehoyada explains this simply; Tosfos - Rebbi
requested that the man not bless out loud to exempt
the others; Rashi (according to Ra'ah) - he did not
want the man to answer 'Amen' to the blessings, for
this is like saying the blessings);
i. A Bas Kol announced that 40 gold pieces is the
value of Birkas ha'Mazon; to this day, this
man's family is among the important families in
(a) (Mishnah): If he covered the blood and it became
uncovered (he is exempt.)
3) A MIXTURE OF BLOOD
(b) Question (Rav Acha brei d'Rava): Why is this different
than returning a lost object?
1. "Hashev" - even 100 times.
(c) Answer (Rav Ashi): "You will cover *it*" teaches, he need
cover only once.
(d) (Mishnah): If the wind covered it (he must cover it.)
(e) (Rabah bar bar Chanah): This is only if it became
uncovered - if not, he is exempt.
(f) Question: The Mitzvah was Nidcheh (unable to be
performed, when it was covered) - the Mitzvah should
never apply again!
(g) Answer (Rav Papa): This teaches that Dichuy does not
apply to Mitzvos.
(h) Question: Why is this different than if the blood was
absorbed into the ground?
1. (Beraisa): If the blood was absorbed into the
ground, one must cover it.
(i) Answer: That is when one can see a discoloration where
the blood was absorbed.
(a) (Mishnah): If the blood became mixed with water, if it
still looks like blood, it must be covered;
1. If blood was mixed with wine, we view the wine as if
it was the same amount of water (and apply the
2. If it was mixed with blood (exempt from Kisuy, e.g.)
of a Behemah or of a Chayah that was not
slaughtered, we view the (exempt blood) as if it was
the same amount of water;
4) THE REQUIRED APPEARANCE OF BLOOD
3. R. Yehudah says, blood does not Mevatel (nullify)
(b) If blood spurted afar, or is on the knife, it must be
(c) R. Yehudah says, one need not cover it if there is other
blood (that can be covered.)
(d) (Gemara - Mishnah): If blood (of a Korban) became mixed
with water, if it has the appearance of blood, it may be
thrown on the Mizbe'ach;
1. If it was mixed with wine, we view the wine as if it
was the same amount of water;
(e) (R. Chiya bar Aba): This is only if the water fell into
the blood, but if blood fell into water, each drop
becomes Batul when it falls in.
2. If it was mixed with Chulin blood, we view the
Chulin blood as if it was the same amount of water;
3. R. Yehudah says, blood does not Mevatel blood.
(f) (Rav Papa): This does not apply to Kisuy ha'Dam - Dichuy
does not apply to Mitzvos. (Once enough blood falls in to
have the appearance of blood, one must cover it.)
(a) (Rav Yehudah): If it looks at all red, it is considered
blood for atonement (on the Mizbe'ach), to Machshir food
(to receive Tum'ah), and for Kisuy.
(b) Question: Mishnayos explicitly teach this regarding
atonement and Kisuy!
(c) Answer: His Chidush is regarding Hechsher.
(d) Question: Clearly, diluted blood is Machshir!
1. If it is considered blood, blood is Machshir; if it
is considered water, water is Machshir!
(e) Answer #1: The case is, it was diluted with rainwater
(which is not Machshir unless one wanted it.)
1. Question: By mixing the rainwater with the blood, he
shows that he wants it, so it is Machshir!
(f) Answer #2 (Rav Asi of Neharvil): Rav Yehudah discusses
the fluid which remains when blood congeals.
2. Answer: The case is, the rainwater fell in the blood
(g) (R. Yirmeyah of Difti): If one eats (a k'Zayis of) such
blood fluid he is Chayav Kares.
1. That is only if it came from a k'Zayis of proper
blood. (Tosfos ha'Rosh - it is possible that the
fluid has a greater volume than the blood it came
(h) (Beraisa): (A Revi'is of) such blood conveys Tum'ah in a
