(י) וְרָאוּ֙ כָּל־עַמֵּ֣י הָאָ֔רֶץ כִּ֛י שֵׁ֥ם יְהוָ֖ה נִקְרָ֣א עָלֶ֑יךָ וְיָֽרְא֖וּ מִמֶּֽךָּ׃
(10) And all the peoples of the earth shall see that the LORD’s name is proclaimed over you, and they shall stand in fear of you.
(ט) וְהָיָה֩ לְךָ֨ לְא֜וֹת עַל־יָדְךָ֗ וּלְזִכָּרוֹן֙ בֵּ֣ין עֵינֶ֔יךָ לְמַ֗עַן תִּהְיֶ֛ה תּוֹרַ֥ת יְהוָ֖ה בְּפִ֑יךָ כִּ֚י בְּיָ֣ד חֲזָקָ֔ה הוֹצִֽאֲךָ֥ יְהֹוָ֖ה מִמִּצְרָֽיִם׃
(9) “And this shall serve you as a sign on your hand and as a reminder on your forehead—in order that the Teaching of the LORD may be in your mouth—that with a mighty hand the LORD freed you from Egypt.
(טז) וְהָיָ֤ה לְאוֹת֙ עַל־יָ֣דְכָ֔ה וּלְטוֹטָפֹ֖ת בֵּ֣ין עֵינֶ֑יךָ כִּ֚י בְּחֹ֣זֶק יָ֔ד הוֹצִיאָ֥נוּ יְהוָ֖ה מִמִּצְרָֽיִם׃ (ס)
(16) “And so it shall be as a sign upon your hand and as a symbol on your forehead that with a mighty hand the LORD freed us from Egypt.”
(ח) וּקְשַׁרְתָּ֥ם לְא֖וֹת עַל־יָדֶ֑ךָ וְהָי֥וּ לְטֹטָפֹ֖ת בֵּ֥ין עֵינֶֽיךָ׃
(8) Bind them as a sign on your hand and let them serve as a symbol on your forehead;
(יח) וְשַׂמְתֶּם֙ אֶת־דְּבָרַ֣י אֵ֔לֶּה עַל־לְבַבְכֶ֖ם וְעַֽל־נַפְשְׁכֶ֑ם וּקְשַׁרְתֶּ֨ם אֹתָ֤ם לְאוֹת֙ עַל־יֶדְכֶ֔ם וְהָי֥וּ לְטוֹטָפֹ֖ת בֵּ֥ין עֵינֵיכֶֽם׃
(18) Therefore impress these My words upon your very heart: bind them as a sign on your hand and let them serve as a symbol on your forehead,
(דברים כח, י) וראו כל עמי הארץ כי שם ה' נקרא עליך ויראו ממך תניא ר"א הגדול אומר אלו תפילין שבראש (שמות לג, כג) והסרותי את כפי וראית את אחורי אמר רב חנא בר ביזנא אמר ר"ש חסידא מלמד שהראה לו הקב"ה למשה קשר של תפילין
With regard to the verse: “And all the nations of the land shall see that the name of the Lord is called upon you, and they shall be afraid of you” (Deuteronomy 28:10), it is taught in a baraita that Rabbi Eliezer the Great says: This is a reference to the phylacteries of the head, upon which the name of God is written, as they demonstrate to all that the name of God is called upon the Jewish people. With regard to the statement of God to Moses: “And I will remove My hand, and you will see My back” (Exodus 33:23), Rav Ḥana bar Bizna says that Rabbi Shimon Ḥasida says: This teaches that the Holy One, Blessed be He, showed Moses the knot of the phylacteries of the head.
ואמר ר"ל כל המניח תפילין מאריך ימים שנאמר (ישעיהו לח, טז) ה' עליהם יחיו ולכל בהן חיי רוחי ותחלימני והחייני:
And Reish Lakish says: Anyone who dons phylacteries lives a long life, as it is stated: “The Lord is upon them, they will live, and altogether therein is the life of my spirit; and have me recover, and make me to live” (Isaiah 38:16). This is interpreted as referring to those who don phylacteries, which contain the name of the Lord, on their heads; as a result, they will live, be healed and merit long life.
ה' עליהם - אותם שנושאין עליהם שם ה' בתפילין יחיו:
(טז) אֲדֹנָ֖י עֲלֵיהֶ֣ם יִֽחְי֑וּ וּלְכָל־בָּהֶן֙ חַיֵּ֣י רוּחִ֔י וְתַחֲלִימֵ֖נִי וְהַחֲיֵֽנִי׃
(16) My Lord, for all that and despite it My life-breath is revived;- You have restored me to health and revived me.
