וְשִׁשָּׁ֣ה קָנִ֔ים יֹצְאִ֖ים מִצִּדֶּ֑יהָ שְׁלֹשָׁ֣ה ׀ קְנֵ֣י מְנֹרָ֗ה מִצִּדָּהּ֙ הָאֶחָ֔ד וּשְׁלֹשָׁה֙ קְנֵ֣י מְנֹרָ֔ה מִצִּדָּ֖הּ הַשֵּׁנִֽי׃
И будет шесть ветвей, выходящих с его сторон: три ветви подсвечника с одной его стороны и три ветви подсвечника с другой его стороны;
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.
