The Talmud records that Channah prayed by moving her lips while her voice was not heard — establishing the paradigm of deep inward, almost silent prayer as the model for the Amidah, highlighting inner over outward expression.
״וְאָהַבְתָּ אֵת ה׳ אֱלֹהֶיךָ״. תַּנְיָא, רַבִּי אֱלִיעֶזֶר אוֹמֵר: אִם נֶאֱמַר ״בְּכָל נַפְשְׁךָ״, לָמָּה נֶאֱמַר ״בְּכָל מְאֹדֶךָ״?, וְאִם נֶאֱמַר ״בְּכָל מְאֹדֶךָ״, לָמָּה נֶאֱמַר ״בְּכָל נַפְשְׁךָ״? אֶלָּא אִם יֵשׁ לְךָ אָדָם שֶׁגּוּפוֹ חָבִיב עָלָיו מִמָּמוֹנוֹ — לְכָךְ נֶאֱמַר ״בְּכָל נַפְשְׁךָ״. וְאִם יֵשׁ לָךְ אָדָם שֶׁמָּמוֹנוֹ חָבִיב עָלָיו מִגּוּפוֹ — לְכָךְ נֶאֱמַר ״בְּכָל מְאֹדֶךָ״. רַבִּי עֲקִיבָא אוֹמֵר: ״בְּכָל נַפְשְׁךָ״ אֲפִילּוּ נוֹטֵל אֶת נַפְשְׁךָ. בְּשָׁעָה שֶׁהוֹצִיאוּ אֶת רַבִּי עֲקִיבָא לַהֲרִיגָה זְמַן קְרִיאַת שְׁמַע הָיָה, וְהָיוּ סוֹרְקִים אֶת בְּשָׂרוֹ בְּמַסְרְקוֹת שֶׁל בַּרְזֶל, וְהָיָה מְקַבֵּל עָלָיו עוֹל מַלְכוּת שָׁמַיִם. אָמְרוּ לוֹ תַּלְמִידָיו: רַבֵּינוּ, עַד כָּאן?! אָמַר לָהֶם: כׇּל יָמַי הָיִיתִי מִצְטַעֵר עַל פָּסוּק זֶה ״בְּכָל נַפְשְׁךָ״ אֲפִילּוּ נוֹטֵל אֶת נִשְׁמָתְךָ. אָמַרְתִּי: מָתַי יָבֹא לְיָדִי וַאֲקַיְּימֶנּוּ, וְעַכְשָׁיו שֶׁבָּא לְיָדִי, לֹא אֲקַיְּימֶנּוּ? הָיָה מַאֲרִיךְ בְּ״אֶחָד״, עַד שֶׁיָּצְתָה נִשְׁמָתוֹ בְּ״אֶחָד״. יָצְתָה בַּת קוֹל וְאָמְרָה: ״אַשְׁרֶיךָ רַבִּי עֲקִיבָא שֶׁיָּצְאָה נִשְׁמָתְךָ בְּאֶחָד״.
We learned in our mishna the explanation of the verse: “And you shall love the Lord your God with all your heart and all your soul and all your might” (Deuteronomy 6:5). This was elaborated upon when it was taught in a baraita: Rabbi Eliezer says: If it is stated: “With all your soul,” why does it state: “With all your might”? Conversely, if it stated: “With all your might,” why does it state: “With all your soul”? Rather, this means that if one’s body is dearer to him than his property, therefore it is stated: “With all your soul”; one must give his soul in sanctification of God. And if one’s money is dearer to him than his body, therefore it is stated: “With all your might”; with all your assets. Rabbi Akiva says: “With all your soul” means: Even if God takes your soul. The Gemara relates: When they took Rabbi Akiva out to be executed, it was time for the recitation of Shema. And they were raking his flesh with iron combs, and he was reciting Shema, thereby accepting upon himself the yoke of Heaven. His students said to him: Our teacher, even now, as you suffer, you recite Shema? He said to them: All my days I have been troubled by the verse: With all your soul, meaning: Even if God takes your soul. I said to myself: When will the opportunity be afforded me to fulfill this verse? Now that it has been afforded me, shall I not fulfill it? He prolonged his uttering of the word: One, until his soul left his body as he uttered his final word: One. A voice descended from heaven and said: Happy are you, Rabbi Akiva, that your soul left your body as you uttered: One.
