previous shiur we learned that the Torah prohibits us to
perform an entire melacha, not part of a melacha
and Chazal, in many cases, prohibited performing part
of a melacha.
Is there a difference between part
of a melacha and part of an amount?
differentiate between çöé îìàëä
and çöé ùéòåø. Doing part
of a melacha such as lifting an item in a reshus
harabim and walking 4 amos and not setting
it down is part of a melacha, because the melacha
is comprised of the above and setting it down (or
standing still). Such an action is ossur
other hand, the Rambam writes
that one who bakes or cooks food the size of a
âøåâøú is chayav,
which means one has violated an issur d’oraisso.
Cooking or baking less than that is also an issur
d’oraisso albeit one is exempt from biblical punishment.
Why this distinction?
çöé îìàëä (part of a
melacha) is not the melacha the Torah refers to
whereas performing a melacha with less of the
required amount -çöé ùéòåø
is the melacha the Torah refers to.
What is the halacha if two people
perform a melacha together?
on whether they could have performed it individually or
whether it requires a joint effort, as follows:-
One person is capable of turning on a light switch
and two people turn it on at the same time, i.e. both press
the switch. Both are pottur (exempt) from biblical
punishment, even when done intentionally.
A heavy package is transported from a reshus
hayachid to a reshus harabim and neither could
have done it individually, both are chayav.
A heavy beam is transported through a reshus
by Reuven and Shimon. Reuven could have carried it himself
but Shimon could not have. Reuven is chayav and
Shimon is pottur, because it is as if Reuven carried
it himself and Shimon merely gave support –

possuk in Vayikra (4:27) says
áòùåúä (when he does it…)
and the gemora Shabbos 92b learns that one person
must perform an entire melacha not part of it and
when two people perform the melacha, neither is
performing the melacha in its entirety.
people cannot perform the melacha individually and
only a joint effort can accomplish it, both are chayav.
The gemora explains that the possuk only
excludes the case when either person or both people could
have accomplished it individually and not when both people
could not have accomplished it.

people to do a melacha together that they can both do

is only ossur mid’rabanan, as the possuk

However, many poskim

merely exempts the perpetrators from bringing a korban.
