Mishnayos Menachos Perek 3 Mishnah 7

With regard to the seven branches of the Candelabrum (see Exodus 25:32), the absence of each prevents fulfillment of the mitzva with the others. With regard to its seven lamps atop the branches, the absence of each prevents fulfillment of the mitzva with the others. With regard to the two passages that are in the mezuza, which are the first (Deuteronomy 6:1–9) and second (Deuteronomy 11:13–21) paragraphs of Shema, the absence of each prevents fulfillment of the mitzva with the other. Furthermore, the absence of even one letter prevents fulfillment of the mitzva with the rest of them. With regard to the four passages that are in the phylacteries, which are the two passages in the mezuza and two additional passages (Exodus 13:1–10, 11–16), the absence of each prevents fulfillment of the mitzva with the others. Furthermore, the absence of even one letter prevents fulfillment of the mitzva with the rest of them. With regard to the four ritual fringes on a garment, the absence of each prevents fulfillment of the mitzva with the others, as the four of them constitute one mitzva. Rabbi Yishmael says: The four of them are four discrete mitzvot, and the absence of one does not prevent fulfillment of the mitzva with the rest.

שִׁבְעָה קְנֵי מְנוֹרָה מְעַכְּבִין זֶה אֶת זֶה. שִׁבְעָה נֵרוֹתֶיהָ מְעַכְּבִין זֶה אֶת זֶה. שְׁתֵּי פָרָשִׁיּוֹת שֶׁבַּמְּזוּזָה מְעַכְּבוֹת זוֹ אֶת זוֹ. וַאֲפִלּוּ כְתָב אֶחָד מְעַכְּבָן. אַרְבַּע פָּרָשִׁיּוֹת שֶׁבַּתְּפִלִּין מְעַכְּבוֹת זוֹ אֶת זוֹ. וַאֲפִלּוּ כְתָב אֶחָד מְעַכְּבָן. אַרְבַּע צִיצִיּוֹת מְעַכְּבוֹת זוֹ אֶת זוֹ, שֶׁאַרְבַּעְתָּן מִצְוָה אֶחָת. רַבִּי יִשְׁמָעֵאל אוֹמֵר, אַרְבַּעְתָּן אַרְבַּע מִצְוֹת:
