Why does the Torah insert the word "u'Keshartam le'Os al Yadecha"?
Refer to 13:9:1:1 & 13:9:1.1:1 and notes.
What are the connotations of "al Yadecha"?
Rashi (on Sh'mos 13:9) and R. Bachye #1: In Sh'mos 13:9, it is written with a 'Hey', so it can be read 'Yad Keiheh', to teach us that it is worn on the weak (left 1 ) arm 2 3 next to the heart.
R. Bachye #2 (citing Menachos 37a): Based on the Pasuk in Yeshayah, 48:13 "Yadi Yasdah Eretz ve'Yemini ... ", 4 we have a tradition that "Yad' S'tam means the left hand. Consequently, we lay Tefilin on the left arm. 5
Hadar Zekenim: If one's right hand is weaker, he puts it on one's right arm.
Even though the Torah wrote "Yadcha". Refer to Sh'mos 13:9:3.1:1 and note
Menachos 37a: Others there learn this via the comparison "u'Keshartam" from "u'Chesavtam" - just like one writes Tefilin with the right hand, so does one bind them on the left arm - next to the heart. Refer to Sh'mos 13:9:3.1:1 4
.
See R. Bachye.
Another opinion in Menachos 37a learns it from the fact that the Pasuk in Eikev 11:18 writes in the same Pasuk as the Mitzvah of Tefilin "Vesamtem es Devarai Eileh al Levavchem".
Whereabout on the left arm does one place the Tefilin shel Yad?
Refer to Sh'mos, 13:9:1:1 and note.
Seeing as in Bo Sh'mos, 13:9, the Torah writes "Vehayu le'Totafos ... " (plural), why does it writes here "Vehayah l'cha le'Os" (singular)?
Refer to Sh'mos, 13:9:1.2:1.
"u'Keshartam le'Os al Yadecha". From where do we know the knots on the shel Yad and the shel Rosh?
Why does the Torah refer to the Tefilin Shel Rosh as "Totafos"?
Rashi (citing Sanhedrin, 4a): The Caspian word 'Tat' and the African word 'Pas', both of which mean 'two' - hinting at the four Parshiyos in the Tefilin Shel Rosh. 1
And each is in its own box, which explains why it is written only about the Tefilin Shel Rosh, but not about the Tefilin Shel Yad, where all four Parshiyos are written on one piece of parchment and placed inside one box.
"Vehayu le'Totafos ... bein Einecha". What are the connotations of "bein Eineicha? Where is the Tefilin shel Rosh worn?
Refer to 13:19:5:1 and notes.
R. Bachye (citing Menachos, 37a): Above the hairline.- the area where the brain of a baby is soft, which we learn from a Gezeirah Shavah "bein Einechem" "bein Einechem" from 'Korchah' in Re'ei, 14:1. 1
See Torah Temimah in Sh'mos, 13:9, note 41.
"Vehayu le'Totafos bein Einecha". What are the implications of "Vehayu" (plural) ?
R. Bachye: It implies that whenever there are Tefilin ?between the eyes', there should be two, and it is therefore forbidden to put on the Tefilin shel Rosh first. 1
Menachos, 36a: It implies that, as long as one is wearing the Tefilin shel Rosh "between the eyes" one should be wearing two Tefilin - in other words one should always remove the Tefilin shel Rosh first. 2
Having taught the Mitzvah of Tefilin in Parshas Bo, why does the Torah repeat it here?
Ramban (on Pasuk 7): In order a. to add the obligation of tying the Tefilin to one's arm and b. to hint at the knot of the Tefilin - which the Chachamim learn from a Halachah le'Moshe mi'Sinai.
Tosfos (Sanhedrin 4b DH 'Tat'): The Torah mentions Tefilin in four places, and they constitute the four Parshiyos that are placed inside the Tefilin.
Why does the Torah juxtapose Mezuzah to Tefilin both here and in Eikev, 11:20?
Oznayim la'Torah: Because they represent "be'Chol Levavcha" - Tefilin shel Yad which are bound beside the heart; "be'Chol Nafsh'cha" - Tefilin shel Rosh. "be'Chol Me'odecha" (with all your money (property) - "be'Chol Me'odecha". 1 Laying Tefilin and affixing a Mezuzah to one's doorpost enables a person to love Hashem with all his heart, with all his Neshamah (thoughts) and with all that he owns. 2
