וְשִׁשָּׁ֣ה קָנִ֔ים יֹצְאִ֖ים מִצִּדֶּ֑יהָ שְׁלֹשָׁ֣ה ׀ קְנֵ֣י מְנֹרָ֗ה מִצִּדָּהּ֙ הָאֶחָ֔ד וּשְׁלֹשָׁה֙ קְנֵ֣י מְנֹרָ֔ה מִצִּדָּ֖הּ הַשֵּׁנִֽי׃
가지 여섯을 등대 곁에서 나오게 하되 그 세 가지는 이편으로 나오고 그 세 가지는 저편으로 나오게 하며
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.
