Mezuzah
Revisited. Parshat Vaetchanan.

By
Chaim Sunitsky.

Rashi on
this Parsha (Devarim 6:9) says that since the word Mezuzot is
written without the Vav[1], only
one Mezuzah is necessary. It’s generally assumed that Rashi can’t argue with a
clear Talmudic statement that every door of the house needs a Mezuzah[2] and
therefore he can’t be understood at face value. However the custom in many
places in Medieval Europe had always been to only affix one Mezuzah per house[3]. We
will now try to examine if indeed there ever was a tradition that supported
this minhag.

The Rema makes a
unique statement in Yoreh Deah (287:2): “The commonly spread minhag in
these countries is to attach only one Mezuzah per house and they have nothing
to rely on”. This statement is very unusual. Rema is known for
supporting Jewish minhagim and it’s very common for him to use the
expression “common minhag” often followed by a statement that this minhag
should not be changed, or at least that this minhag can be relied on.
Here however the Rema is saying just the opposite: the minhag has
nothing to rely on and a “yere Shamaim” person should affix the Mezuzot
on every entrance.

It’s hard to understand
how this incorrect “minhag” could have possibly become wide spread. R. Yissachar
Dov Eilenburg[4]
(the author of Beer Sheva on the Talmud) suggested that this mistake became
widespread due to incorrect understanding of our Rashi. However I find
it strange if the previous minhag was to affix a Mezuzah on every
doorpost, how would it change in many countries simply because they misunderstood
the Rashi’s Torah commentary[5]. As
for the correct understanding of Rashi, two possibilities were offered:
either Rashi is saying that we don’t have to affix two Mezuzot on each
doorframe[6], or
that Rashi is following the opinion of R. Meir that if an entrance has
only one doorpost on the right, there is a need to affix Mezuzah (despite the
lack of second doorpost[7]). As
for Rashi’s actual drasha[8]
we don’t see it in any known source in Hazal[9].

In general there was[10] some
attempt to explain the custom of affixing only one Mezuzah based on the fact
that many of the inside rooms in their houses were not clean enough, but this
does not explain what people relied on when the house itself had more than one
entrance[11].
However Rashi[12]
on our Gemorah brings an interpretation according to which if a house
has exactly two entrances, it needs only one Mezuzah on the more commonly used
entrance, since the other entrance is batela (is unimportant) compared
to the first one. Only if the house has more than two entrances then we don’t
say that two entrances are batelim to the one commonly used entrance.
Maybe then Rashi on the Chumash is following his shita and
saying that a house (or room) with two entrances requires only one Mezuzah. Interestingly,
in Yerushalmi[13]
there is even a stronger statement that seems to imply that only one entrance per
house requires a Mezuzah:

בית
שיש לו שני פתחים נותן ברגיל היו שניהן רגילין נותן בחזית היו שניהן חזית נותן על איזה
מהן שירצה

The simple meaning of Yerushlami
seems to contradict the Talmud Bavli and imply that only the entrance that’s
used more often needs the Mezuzah. If he uses both entrances equally, then the
Mezuzah is affixed to the “stronger” entrance and is they are equally strong,
one can affix the Mezuzah on either entrance.

To conclude we seem to
have found a possible explanation of Rashi according to the simple
meaning of his words[14] and
a possible justification for the old minhag in Europe[15]. Needless
to say our words are only theoretical and Baruch Hashem that minhag has
disappeared a long time ago and every Orthodox Jew today affixes a Mezuzah on
every entrance.
