Where does the text about the patriarchs come from?
וַיֹּ֩אמֶר֩ ע֨וֹד אֱלֹקִ֜ים אֶל־מֹשֶׁ֗ה כֹּֽה־תֹאמַר֮ אֶל־בְּנֵ֣י יִשְׂרָאֵל֒ ה' אֱלֹקֵ֣י אֲבֹתֵיכֶ֗ם אֱלֹקֵ֨י אַבְרָהָ֜ם אֱלֹקֵ֥י יִצְחָ֛ק וֵאלֹקֵ֥י יַעֲקֹ֖ב שְׁלָחַ֣נִי אֲלֵיכֶ֑ם זֶה־שְּׁמִ֣י לְעֹלָ֔ם וְזֶ֥ה זִכְרִ֖י לְדֹ֥ר דֹּֽר׃
And God said moreover to Moshe, Thus shalt thou say to the children of Yisra᾽el, The Lord God of your fathers, the God of Avraham the God of Yitzchak, and the God of Ya'akov, has sent me to you: this is my name for ever, and this is my memorial to all generations.
אַחַ֣ר ׀ הַדְּבָרִ֣ים הָאֵ֗לֶּה הָיָ֤ה דְבַר־ה' אֶל־אַבְרָ֔ם בַּֽמַּחֲזֶ֖ה לֵאמֹ֑ר אַל־תִּירָ֣א אַבְרָ֗ם אָנֹכִי֙ מָגֵ֣ן לָ֔ךְ שְׂכָרְךָ֖ הַרְבֵּ֥ה מְאֹֽד׃
Some time later, the word of the LORD came to Abram in a vision. He said,
“Fear not, Abram,
I am a shield to you;
Your reward shall be very great.”
Can you change a blessing? Can you add to a blessing?
אָמַר רַב הוּנָא: טָעָה בְּשָׁלֹשׁ רִאשׁוֹנוֹת — חוֹזֵר לָרֹאשׁ. ... אָמַר רַב יְהוּדָה: לְעוֹלָם אַל יִשְׁאַל אָדָם צְרָכָיו לֹא בְּשָׁלֹשׁ רִאשׁוֹנוֹת, וְלֹא בְּשָׁלֹשׁ אַחֲרוֹנוֹת, אֶלָּא בְּאֶמְצָעִיּוֹת. דְּאָמַר רַבִּי חֲנִינָא: רִאשׁוֹנוֹת — דּוֹמֶה לְעֶבֶד שֶׁמְּסַדֵּר שֶׁבַח לִפְנֵי רַבּוֹ. אֶמְצָעִיּוֹת — דּוֹמֶה לְעֶבֶד שֶׁמְבַקֵּשׁ פְּרָס מֵרַבּוֹ. אַחֲרוֹנוֹת — דּוֹמֶה לְעֶבֶד שֶׁקִּבֵּל פְּרָס מֵרַבּוֹ, וְנִפְטָר וְהוֹלֵךְ לוֹ.
Rav Huna said: One who erred in any of the first three blessings he must return to the beginning of the Amida prayer because the first three blessing comprise a single entity. ... Rav Yehuda said: There is an additional distinction between the various sections of the Amida prayer: One must never request his own needs in the first three or in the last three blessings; rather, he should do so in the middle blessings. As Rabbi Ḥanina said: During the first three blessings, he is like a servant who arranges praise before his master; during the middle blessings, he is like a servant who requests a reward from his master; during the final three blessings, one is like a servant who already received a reward from his master and is taking his leave and departing.
(ה) וְנֹסַח כָּל הַבְּרָכוֹת עֶזְרָא וּבֵית דִּינוֹ תִּקְּנוּם. וְאֵין רָאוּי לְשַׁנּוֹתָם וְלֹא לְהוֹסִיף עַל אַחַת מֵהֶם וְלֹא לִגְרֹעַ מִמֶּנָּה. וְכָל הַמְשַׁנֶּה מִמַּטְבֵּעַ שֶׁטָּבְעוּ חֲכָמִים בַּבְּרָכוֹת אֵינוֹ אֶלָּא טוֹעֶה. וְכָל בְּרָכָה שֶׁאֵין בָּהּ הַזְכָּרַת הַשֵּׁם וּמַלְכוּת אֵינָהּ בְּרָכָה אֶלָּא אִם כֵּן הָיְתָה סְמוּכָה לַחֲבֵרְתָהּ:
(ו) וְכָל הַבְּרָכוֹת כֻּלָּן נֶאֱמָרִין בְּכָל לָשׁוֹן וְהוּא שֶׁיֹּאמַר כְּעֵין שֶׁתִּקְּנוּ חֲכָמִים. וְאִם שִׁנָּה אֶת הַמַּטְבֵּעַ הוֹאִיל וְהִזְכִּיר אַזְכָּרָה וּמַלְכוּת וְעִנְיַן הַבְּרָכָה אֲפִלּוּ בִּלְשׁוֹן חֹל יָצָא:
(5) The text of all the blessings was ordained by Ezra and his court. It is not fit to alter it, to add to it, or to detract from it. Whoever alters the text of a blessing from that ordained by the Sages is making an error.
A blessing that does not include the mention of God's name and His sovereignty [over the world] is not considered a blessing unless it is recited in proximity to a blessing [which meets these criteria].
(6) All the blessings may be recited in any language, provided one recites [a translation of] the text ordained by the Sages. [A person who] changes that text fulfills his obligation nonetheless - since he mentioned God's name, His sovereignty, and the subject of the blessing - although he did so in a ordinary language.
(ט) ... וְשָׁלֹשׁ רִאשׁוֹנוֹת וְשָׁלֹשׁ אַחֲרוֹנוֹת לְעוֹלָם אֵין מוֹסִיפִין בָּהֶן וְלֹא פּוֹחֲתִין מֵהֶן וְאֵין מְשַׁנִּין בָּהֶן דָּבָר:
... In the first three [blessings] and the last three [blessings], one must never add, detract or change anything at all.
Why mention matriarchs? / In prayer, truth can outrank tradition
אֲתָא מֹשֶׁה, אָמַר: ״הָאֵל הַגָּדוֹל הַגִּבּוֹר וְהַנּוֹרָא״.

אֲתוֹ אִינְהוּ וְאָמְרוּ: אַדְּרַבָּה, זוֹ הִיא (גְּבוּרַת) גְּבוּרָתוֹ: שֶׁכּוֹבֵשׁ אֶת יִצְרוֹ — שֶׁנּוֹתֵן אֶרֶךְ אַפַּיִם לָרְשָׁעִים. וְאֵלּוּ הֵן נוֹרְאוֹתָיו — שֶׁאִלְמָלֵא מוֹרָאוֹ שֶׁל הַקָּדוֹשׁ בָּרוּךְ הוּא הֵיאַךְ אוּמָּה אַחַת יְכוֹלָה לְהִתְקַיֵּים בֵּין הָאוּמּוֹת?
וְרַבָּנַן: הֵיכִי עָבְדִי הָכִי וְעָקְרִי תַּקַּנְתָּא דְּתַקֵּין מֹשֶׁה? אָמַר רַבִּי אֶלְעָזָר: מִתּוֹךְ שֶׁיּוֹדְעִין בְּהַקָּדוֹשׁ בָּרוּךְ הוּא שֶׁאֲמִתִּי הוּא, לְפִיכָךְ לֹא כִּיזְּבוּ בּוֹ.
Moses came and said in his prayer: “The great, the mighty, and the awesome God” (Deuteronomy 10:17).
Jeremiah the prophet came and said: Gentiles, i.e., the minions of Nebuchadnezzar, are carousing in His sanctuary; where is His awesomeness? Therefore, he did not say awesome in his prayer: “The great God, the mighty Lord of Hosts, is His name” (Jeremiah 32:18).
Daniel came and said: Gentiles are enslaving His children; where is His might? Therefore he did not say mighty in his prayer: “The great and awesome God” (Daniel 9:4).
The members of the Great Assembly came and said: On the contrary, this is the might of His might, i.e., this is the fullest expression of it, that He conquers His inclination in that He exercises patience toward the wicked. God’s anger is flared by the gentile nations’ enslavement of His people, yet He expresses tremendous might by suppressing His anger and holding back from punishing them immediately. Therefore, it is still appropriate to refer to God as mighty. And these acts also express His awesomeness: Were it not for the awesomeness of the Holy One, Blessed be He, how could one people, i.e., the Jewish people, who are alone and hated by the gentile nations, survive among the nations?
The Gemara asks: And the Rabbis, i.e., Jeremiah and Daniel, how could they do this and uproot an ordinance instituted by Moses, the greatest teacher, who instituted the mention of these attributes in prayer? Rabbi Elazar said: They did so because they knew of the Holy One Blessed be He, that He is truthful and hates a lie. Consequently, they did not speak falsely about Him. Since they did not perceive His attributes of might and awesomeness, they did not refer to them; therefore, they cannot be criticized for doing so.

Nonetheless, adding words in keeping with the blessing’s theme or in keeping with the theme of the day, which are praises to God related to the blessing’s theme is perfectly permissible… And based on this reasoning, the practice is to say piyyutim on the theme of the blessings… and even in the first three blessings of the Amidah…
The authentic and traditional way to add the Imahot to the Amidah is to compose a short piyyut or several short piyyutim which will be recited in the middle of Avot or in the middle of other blessings of the Amidah. In this way, the Imahot can be added without changing the ancient wording of the Amidah itself.
Rabbi Dr. Einat Ramon , the Dean of the Schechter Rabbinical Seminary in Jerusalem , has composed such a piyyut and it is found in an Appendix to this teshuvah . I hope that such piyyutim will be adopted by synagogues who wish to incorporate the Imahot into the Amidah in a halakhic and authentic fashion.

Let us come to the tents of Sarah, Rebecca, Rachel, and Leah,
And let their acts of kindness be before us at all times

(12) And Sarah laughed to herself, saying, “Now that I’ve lost the ability, am I to have enjoyment—with my husband so old?”
(כב) וַיִּתְרֹֽצְצ֤וּ הַבָּנִים֙ בְּקִרְבָּ֔הּ וַתֹּ֣אמֶר אִם־כֵּ֔ן לָ֥מָּה זֶּ֖ה אָנֹ֑כִי וַתֵּ֖לֶךְ לִדְרֹ֥שׁ אֶת־ה'׃
(22) But the children struggled in her womb, and she said, “If so, why do I exist?” She went to inquire of ה',

(15) Thus said the LORD:
A cry is heard in Ramah-e—
Wailing, bitter weeping—
Rachel weeping for her children.
She refuses to be comforted
For her children, who are gone. (16) Thus said the LORD:
Restrain your voice from weeping,
Your eyes from shedding tears;
For there is a reward for your labor
—declares the LORD:
They shall return from the enemy’s land.

The Sages taught in a baraita: One may only call three people patriarchs, Abraham, Isaac, and Jacob, but not Jacob’s children. And one may only call four people matriarchs, Sarah, Rebecca, Rachel, and Leah. The Gemara asks: What is the reason for this exclusivity with regard to the Patriarchs? ... the reason the sons of Jacob are not called patriarchs is because until Jacob they are significant enough to be referred to as patriarchs, but beyond Jacob, they are not significant enough to be referred to as patriarchs.
