וְשִׁשָּׁ֣ה קָנִ֔ים יֹצְאִ֖ים מִצִּדֶּ֑יהָ שְׁלֹשָׁ֣ה ׀ קְנֵ֣י מְנֹרָ֗ה מִצִּדָּהּ֙ הָאֶחָ֔ד וּשְׁלֹשָׁה֙ קְנֵ֣י מְנֹרָ֔ה מִצִּדָּ֖הּ הַשֵּׁנִֽי׃
"E seis braços sairão de seus lados; três braços do candelabro de um lado, e três braços do candelabro do outro lado.
Mishnah Menachot
Regarding the seven branches of the menorah, the [absence of] one invalidates the others. Regarding the seven lamps on it, the [absence of] one invalidates the others. Regarding the two portions of Scripture in the mezuzah, the [absence of] one invalidates the other; indeed even one letter can invalidate the whole. Regarding the four portions of Scripture in the tefillin, the [absence of] one invalidates the others; indeed even one letter can invalidate the whole. Regarding the four fringes, the [absence of] one invalidates the others, since the four together form one mitzvah. Rabbi Ishmael says: the four are four separate mitzvot.
