Before putting on tefillin. This paragraph says what to have in mind:
לְשֵׁם יִחוּד קוּדְשָׁא בְּרִיךְ הוּא וּשְׁכִינְתֵּהּ בִּדְחִילוּ וּרְחִימוּ, לְיַחֵד שֵׁם י"ה בו"ה בְּיִחוּדָא שְׁלִים בְּשֵׁם כָּל יִשְׂרָאֵל,
For the sake of uniting the Holy One, blessed is He, and His Presence, in awe and love, to unite the Name, Yud-Hei with Vav-Hei, in complete unity, in the name of all Israel.
What it means
Much of this sentence is Aramaic, the language of the Zohar (the central book of Kabbalah). The pair "awe and love" appears in the Tikkunei Zohar (a companion book to the Zohar), which says that Torah without awe and love "does not fly upward."
Tikkunei Zohar 25bהִנְּנִי מְכַוֵּן בַּהֲנָחַת תְּפִלִּין לְקַיֵּם מִצְוַת בּוֹרְאִי, שֶׁצִּוָּנוּ לְהָנִיחַ תְּפִלִּין כַּכָּתוּב בְּתוֹרָתוֹ וּקְשַׁרְתָּם לְאוֹת עַל יָדֶךָ, וְהָיוּ לְטֹטָפֹת בֵּין עֵינֶיךָ,
Here I am, aiming my mind, as I put on tefillin, to fulfill the commandment of my Creator, who commanded us to put on tefillin, as it is written in His Torah: "Tie them as a sign on your arm, and they shall be totafot between your eyes."
What it means
Here I am. As I put on tefillin, I mean to fulfill the commandment of my Creator, who commanded us to put on tefillin, as it is written in His Torah: "Tie them as a sign on your arm, and they shall be totafot between your eyes."
The rest of this paragraph is a checklist of what to have in mind. Its core is taken almost word for word from the Tur (a law code from the 1300s) and the Shulchan Aruch (the main code of Jewish law). The Mishnah Berurah (a standard guide to daily Jewish law, around 1900) adds: if all you had in mind was doing the mitzvah, it still counts.
Tur, Orach Chaim 25; Shulchan Aruch, Orach Chaim 25:5; Mishnah Berurah 25:15וְהֵם אַרְבַּע פַּרְשִׁיּוֹת אֵלּוּ, שְׁמַע. וְהָיָה אִם שָׁמֹעַ. קַדֶּשׁ. וְהָיָה כִי יְבִאֲךָ. שֶׁיֵּשׁ בָּהֶם יִחוּדוֹ וְאַחְדּוּתוֹ יִתְבָּרַךְ שְׁמוֹ בָּעוֹלָם,
They are these four passages: Shema ("Hear"), Vehayah Im Shamoa ("If you listen"), Kadesh ("Make holy"), and Vehayah Ki Yeviakha ("When He brings you"). They contain His being the only One, and His oneness, may His name be blessed, in the world.
What it means
They are these four passages: Shema, Vehayah Im Shamoa, Kadesh, and Vehayah Ki Yeviakha. They contain His being the only One and His oneness in the world, may His name be blessed.
In the Torah, Kadesh and Vehayah Ki Yeviakha come first. This list puts the two Shema passages first. Rav Kook (the first Chief Rabbi of the Land of Israel, who died in 1935) explains the order: first you accept God as King and take on the mitzvot. That is what makes you ready to take in the memory of leaving Egypt.
Rav Kook, Olat Re'iyah, Tefillinוְשֶׁנִּזְכֹּר נִסִּים וְנִפְלָאוֹת, שֶׁעָשָׂה עִמָּנוּ בְּהוֹצִיאוֹ אוֹתָנוּ מִמִּצְרָיִם, וַאֲשֶׁר לוֹ הַכֹּחַ וְהַמֶּמְשָׁלָה בָּעֶלְיוֹנִים וּבַתַּחְתּוֹנִים לַעֲשׂוֹת בָּהֶם כִּרְצוֹנוֹ,
And so that we remember the miracles and wonders that He did for us when He took us out of Egypt, and that His are the power and the rule over those above and those below, to do with them as He wants.
What it means
And so that we remember the miracles and wonders He did for us when He took us out of Egypt, and that the power and the rule are His, over those above and those below, to do with them as He wants.
The Torah itself ties tefillin to leaving Egypt: "a sign on your arm and a reminder between your eyes ... because with a strong hand Hashem took you out of Egypt" (Shemot 13:9). Ramban (Nachmanides, Spain, 1200s): the root of the mitzvah is to place the written record of the Exodus on the arm and the head, facing the heart and the brain, where thought lives.
Shemot 13:9; Ramban on Shemot 13:16וְצִוָּנוּ לְהָנִיחַ עַל הַיָּד, לְזִכְרוֹן זְרוֹעַ הַנְּטוּיָה. וְשֶׁהִיא נֶגֶד הַלֵּב לְשַׁעְבֵּד בָּזֶה תַּאֲוַת וּמַחְשְׁבוֹת לִבֵּנוּ לַעֲבוֹדָתוֹ יִתְבָּרַךְ שְׁמוֹ,
He commanded us to put it on the arm as a reminder of the outstretched arm, and since it faces the heart, to bind by this the desire and thoughts of our heart to His service, may His name be blessed.
What it means
He commanded us to put tefillin on the arm as a reminder of His outstretched arm. And since the arm faces the heart, by this we bind the desire and thoughts of our heart to His service, may His name be blessed.
Why the upper arm? One answer in the Gemara, from Rabbi Yitzchak, reads "Put these words of Mine on your heart" as a rule about place: the tefillin has to sit facing the heart. So the Shulchan Aruch says to tilt it a little toward your body. Then, when you lower your arm, it faces your heart.
Menachot 37b; Shulchan Aruch, Orach Chaim 27:1וְעַל הָרֹאשׁ נֶגֶד הַמּוֹחַ, שֶׁהַנְּשָׁמָה שֶׁבְּמוֹחִי עִם שְׁאָר חוּשַׁי וְכֹחוֹתַי כֻּלָּם יִהְיוּ מְשֻׁעְבָּדִים לַעֲבוֹדָתוֹ יִתְבָּרַךְ שְׁמוֹ,
And on the head, facing the brain, so that the soul in my brain, with the rest of my senses and powers, may all be bound to His service, may His name be blessed.
What it means
And on the head, facing the brain, so that the soul in my brain, along with the rest of my senses and powers, may all be bound to His service, may His name be blessed.
"Between your eyes" does not mean on your forehead. The Gemara says it means the top of the head, the spot where a baby's skull is still soft. So the head tefillin sits from the hairline up, over the brain. It is centered, which lines it up with the space between your eyes.
Menachot 37a; Shulchan Aruch, Orach Chaim 27:9-10וּמִשֶּׁפַע מִצְוַת תְּפִלִּין יִתְמַשֵּׁךְ עָלַי לִהְיוֹת לִי חַיִּים אֲרֻכִּים, וְשֶׁפַע קֹדֶשׁ, וּמַחֲשָׁבוֹת קְדוֹשׁוֹת, בְּלִי הִרְהוּר חֵטְא וְעָוֹן כְּלָל
From the flow of the mitzvah of tefillin may some be drawn onto me, to give me long life, a flow of holiness, and holy thoughts, with no thought of sin or wrongdoing at all.
What it means
From the flow of the mitzvah of tefillin, may I be given long life, a flow of holiness, and holy thoughts, with no thought of sin or wrongdoing at all.
Asking for long life here has a source. In the Gemara, Reish Lakish says that whoever puts on tefillin lives long. He learns it from a verse in Yeshayahu (38:16), which the Gemara quotes as "Hashem is upon them, they will live." Rashi (the classic commentator, France, died 1105) explains: those who carry God's name on them, in their tefillin, will live.
Menachot 44a-44b, with Rashiוְשֶׁלֹּא יְפַתֵּנוּ וְלֹא יִתְגָּרֶה בָּנוּ יֵצֶר הָרָע, וְיַנִּיחֵנוּ לַעֲבֹד אֶת יְיָ, כַּאֲשֶׁר עִם לְבָבֵנוּ,
May it not tempt us or pick a fight with us, the urge to do wrong, and may it leave us to serve Hashem as our heart wants to.
What it means
May the urge to do wrong not tempt us or pick a fight with us. May it leave us to serve Hashem the way our heart wants to.
Two verbs, two tactics. Rav Kook reads "tempt" as steering the energy a mitzvah gives you toward the wrong things, and "pick a fight" as pushing back against the holiness head on. And he reads the last words this way: the pure wish to serve God is already in the heart. The request is only that nothing trip it up.
Rav Kook, Olat Re'iyah, Tefillinוִיהִי רָצוֹן מִלְּפָנֶיךָ, יְיָ אֱלֹהֵינוּ, וֵאלֹהֵי אֲבוֹתֵינוּ, שֶׁתְּהֵא חֲשׁוּבָה מִצְוַת הֲנָחַת תְּפִלִּין, לִפְנֵי הַקָּדוֹשׁ בָּרוּךְ הוּא, כְּאִלּוּ קִיַּמְתִּיהָ בְּכָל פְּרָטֶיהָ וְדִקְדּוּקֶיהָ, וְכַוָּנוֹתֶיהָ, וְתַרְיַ"ג מִצְווֹת הַתְּלוּיוֹת בָּהּ, אָמֵן סֶלָה.
And may it be Your will, Hashem, our God and God of our ancestors, that the mitzvah of putting on tefillin be counted before the Holy One, blessed is He, as if I had kept it in all its details, fine points and intentions, along with the 613 mitzvot that depend on it. Amen, selah.
What it means
These closing words are a formula. This siddur ends its paragraph before the tallit the same way. The Gemara does link tefillin to the rest of the Torah. From "so that Hashem's Torah will be in your mouth" (Shemot 13:9) it says "the whole Torah is compared to tefillin," and it uses that to learn a law about other mitzvot from tefillin.
Kiddushin 35aPlace the arm tefillin on the muscle of your weaker upper arm (the left, for most people). Before you tighten it, say:
בָּרוּךְ אַתָּה יְיָ אֱלֹהֵינוּ מֶלֶךְ הָעוֹלָם אֲשֶׁר קִדְּשָׁנוּ בְּמִצְוֹתָיו וְצִוָּנוּ לְהָנִיחַ תְּפִלִּין.
Blessed are You, Hashem our God, King of the world who made us holy with His commandments and commanded us to put on tefillin.
What it means
The Gemara gives both tefillin blessings: this one when you put tefillin on your arm, the next one for your head. You say it before tightening because a blessing on a mitzvah comes right before the act. For tefillin, the Shulchan Aruch says, the act is the tying.
Berakhot 60b; Shulchan Aruch, Orach Chaim 25:8Tighten it. Wind the strap seven times on your forearm. Set the head tefillin high, centered above your eyes. Before tightening:
בָּרוּךְ אַתָּה יְיָ אֱלֹהֵינוּ מֶלֶךְ הָעוֹלָם אֲשֶׁר קִדְּשָׁנוּ בְּמִצְוֹתָיו וְצִוָּנוּ עַל מִצְוַת תְּפִלִּין.
Blessed are You, Hashem our God, King of the world who made us holy with His commandments and commanded us about the mitzvah of tefillin.
What it means
Not everyone says this blessing. The Gemara: if you did not talk in between, one blessing. If you talked, two. The Shulchan Aruch rules that the first blessing covers both tefillin, and so does the siddur of the first Chabad Rebbe. The Rema (Rabbi Moshe Isserles, who added Ashkenazi practice to the Shulchan Aruch) records the Ashkenazi custom: always both.
Menachot 36a; Shulchan Aruch and Rema, Orach Chaim 25:5; Piskei HaSiddur, TefillinTighten the head tefillin. Then right away:
בָּרוּךְ שֵׁם כְּבוֹד מַלְכוּתוֹ לְעוֹלָם וָעֶד.
Blessed is the name of His glorious kingdom forever and ever.
What it means
Why this line here? The Rema says it is good to always add it after the second blessing. The Mishnah Berurah explains: Ashkenazim hold the blessing is required. The line is there only to be extra safe, in case the blessing was said for nothing. It warns: say the line only after the head tefillin is tight, so nothing comes between blessing and act.
Rema, Orach Chaim 25:5; Mishnah Berurah 25:21; Kitzur Shulchan Aruch 10:4With the head tefillin tight, say:
וּמֵחָכְמָתְךָ אֵל עֶלְיוֹן תַּאֲצִיל עָלַי וּמִבִּינָתְךָ תְּבִינֵנִי וּבְחַסְדְּךָ תַּגְדִּיל עָלַי וּבִגְבוּרָתְךָ תַּצְמִית אוֹיְבַי וְקָמַי וְשֶׁמֶן הַטּוֹב תָּרִיק עַל שִׁבְעָה קְנֵי הַמְּנוֹרָה לְהַשְׁפִּיעַ טוּבְךָ לִבְרִיּוֹתֶיךָ.
And from Your wisdom, God Most High, pass some on to me. From Your understanding, give me understanding. With Your kindness, do great things for me. With Your strength, cut down my enemies and attackers. Pour the good oil onto the seven branches of the menorah, to send Your goodness to Your creatures.
What it means
And from Your wisdom, God Most High, pass some on to me. From Your understanding, give me understanding. With Your kindness, do great things for me. With Your strength, cut down my enemies and those who rise against me. Pour the good oil onto the seven branches of the menorah, to send Your goodness to Your creatures.
Four requests: wisdom, understanding, kindness, strength. Rabbi Aharon of Karlin (a Chassidic rebbe of the 1800s, in what is now Belarus) matches them to the four Torah passages in the tefillin, one each. The prayer is not from the Gemara. Shevet Musar, a book of ethics first printed in 1712, gives it as words to say after putting on tefillin.
Beit Aharon, Parashat Bo; Shevet Musar, chapter 31פּוֹתֵחַ אֶת יָדֶךָ וּמַשְׂבִּיעַ לְכָל חַי רָצוֹן.
You open Your hand and satisfy every living thing with what it wants.
What it means
Count the Hebrew words of this verse: seven. The Aruch HaShulchan (a law code by Rabbi Yechiel Michel Epstein of Novardok, finished around 1900) says the seven windings on the arm match the seven words of this verse.
Aruch HaShulchan, Orach Chaim 27:19Then wind the arm strap three times around your middle finger, and say:
וְאֵרַשְׂתִּיךְ לִי לְעוֹלָם, וְאֵרַשְׂתִּיךְ לִי בְּצֶדֶק וּבְמִשְׁפָּט וּבְחֶסֶד וּבְרַחֲמִים.
I will betroth you to Me forever. I will betroth you to Me with what is right and with justice, with kindness and with compassion.
What it means
These are God's words to the people of Israel in the book of Hoshea (2:21-22), spoken like a groom to a bride. "I will betroth you" comes three times. Kaf HaChaim (a law commentary by Rabbi Yaakov Chaim Sofer, Jerusalem, early 1900s) quotes an older book: the three windings on your finger match those three, so these verses are said as you wind.
Hoshea 2:21-22; Kaf HaChaim, Orach Chaim 25:68וְאֵרַשְׂתִּיךְ לִי בֶּאֱמוּנָה, וְיָדַעַתְּ אֶת יְיָ.
I will betroth you to Me with faithfulness, and you will know Hashem.
What it means
Rashi splits the list in these two verses. Right and justice are what you bring. Kindness and compassion are what comes back to you from God because of them. And "with faithfulness" is the reward for trusting, all through the exile, the promises God made through the prophets.
Rashi on Hoshea 2:21-22
