The Shema in History

שְׁמַ֖ע יִשְׂרָאֵ֑ל יְהֹוָ֥ה אֱלֹהֵ֖ינוּ יְהֹוָ֥ה ׀ אֶחָֽד׃ וְאָ֣הַבְתָּ֔ אֵ֖ת יְהֹוָ֣ה אֱלֹהֶ֑יךָ בְּכׇל־לְבָבְךָ֥ וּבְכׇל־נַפְשְׁךָ֖ וּבְכׇל־מְאֹדֶֽךָ׃

Deuteronomy 6:4-5

Hear, O Israel! יהוה is our God, יהוה alone. You shall love your God יהוה with all your heart and with all your soul and with all your might.

‘Ἀγαπήσεις κύριον τὸν Θεόν σου ἐν ὅλῃ τῇ καρδίᾳ σου καὶ ἐν ὅλῃ τῇ ψυχῇ σου καὶ ἐν ὅλῃ τῇ διανοίᾳ σου.’

Gospel of Matthew 23:37b

 ‘Love the Lord your God with all your heart and with all your soul and with all your mind.’

Ἄκουε, Ἰσραήλ, Κύριος ὁ Θεὸς ἡμῶν Κύριος εἷς ἐστιν, καὶ ἀγαπήσεις Κύριον τὸν Θεόν σου ἐξ ὅλης τῆς καρδίας σου καὶ ἐξ ὅλης τῆς ψυχῆς σου καὶ ἐξ ὅλης τῆς διανοίας σου καὶ ἐξ ὅλης τῆς ἰσχύος σου

Gospel of Mark 12:29b–30

‘Hear O Israel, the Lord our God, the Lord is One. Love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.’

Ἀγαπήσεις Κύριον τὸν Θεόν σου ἐξ ὅλης τῆς καρδίας σου καὶ ἐν ὅλῃ τῇ ψυχῇ σου καὶ ἐν ὅλῃ τῇ ἰσχύϊ σου καὶ ἐν ὅλῃ τῇ διανοίᾳ σου,’ καὶ ‘Τὸν πλησίον σου ὡς σεαυτόν.’

Luke 10:27b

 ‘Love the Lord your God with all your heart and with all your soul and with all your strength and with all your mind’ and ‘Love your neighbor as yourself.’

And here's how it shows up in liturgy:

סידור ספרד, שחרית לימות החול, ק"ש וברכותיה כ׳-כ״ג

שְׁמַע יִשְׂרָאֵל יְהֹוָה אֱלֹהֵֽינוּ יְהֹוָה אֶחָד: יש להפסיק מעט בין אחד לברוך כי עיקר קבול עול מלכות שמים היא פסוק ראשון. ויאמר בלחש: בָּרוּךְ שֵׁם כְּבוֹד מַלְכוּתוֹ לְעוֹלָם וָעֶד: וְאָהַבְתָּ אֵת יְהֹוָה אֱלֹהֶֽיךָ בְּכָל֯־לְ֯בָבְךָ וּבְכָל־נַפְשְׁךָ וּבְכָל־מְאֹדֶֽךָ: וְהָיוּ הַדְּ֒בָרִים הָאֵֽלֶּה אֲשֶׁר֯ אָ֯נֹכִי מְצַוְּךָ הַיּוֹם עַל֯־לְ֯בָבֶֽךָ: וְשִׁנַּנְתָּם לְבָנֶֽיךָ וְדִבַּרְתָּ בָּם בְּשִׁבְתְּ֒ךָ בְּבֵיתֶֽךָ וּבְלֶכְתְּ֒ךָ בַדֶּֽרֶךְ וּבְשָׁכְבְּ֒ךָ וּבְקוּמֶֽךָ: וּקְשַׁרְתָּם לְאוֹת עַל֯־יָ֯דֶֽךָ וְהָיוּ לְטֹטָפֹת בֵּין עֵינֶֽיךָ: וּכְתַבְתָּם עַל־מְזֻזוֹת בֵּיתֶֽךָ וּבִשְׁעָרֶֽיךָ:

Siddur Sefard, Weekday Shacharit, The Shema 20-23

Hear, Israel: Adonoy is our God, Adonoy is One. The following two lines are to be said silently: Blessed [is His] Name, Whose glorious kingdom is forever and ever. And you shall love Adonoy your God with all your heart and with all your soul and with all your possessions. And these words which I command you today, shall be upon your heart. And you shall teach them sharply to your children. And you shall discuss them when you sit in your house, and when you travel on the road, and when you lie down and when you rise. And you shall bind them for a sign upon your hand, and they shall be for totafos between your eyes. And you shall write them upon the doorposts of your house and upon your gateways.
