What is the Amidah prayer?

The Amidah (lit. "the standing") is the central prayer of Jewish liturgy, recited three times daily while standing. It consists of nineteen blessings (originally eighteen, hence its alternative name Shemoneh Esrei, "eighteen") covering praise of God, personal and communal petitions, and thanksgiving. It is considered the quintessential act of tefillah (prayer) in Jewish tradition.

Key Takeaways

The Amidah is the core prayer recited at all three daily prayer services (Shacharit, Mincha, and Maariv).
Its name means "standing," as it must be recited while standing with feet together, facing Jerusalem.
The Talmud traces its origins to the three Patriarchs — Abraham, Isaac, and Jacob — who each instituted one of the daily prayers.
It contains 19 blessings: 3 of praise, 13 of petition, and 3 of thanksgiving.
Special insertions, such as Al HaNissim on Chanukah and Purim, are added within the thanksgiving blessing.

Structure and Name

The prayer is known by two names:

Amidah (עֲמִידָה) — "standing," referring to the posture required during recitation.
Shemoneh Esrei — "eighteen," the original number of blessings, though a nineteenth was added (the blessing against heretics, Birkat HaMinim) by Rabban Gamliel in Yavneh.

It is also simply called "HaTefillah" (הַתְּפִלָּה) — "The Prayer" — indicating its supreme status among all prayers [Talmud Bavli, Berakhot 26b].

Origins: The Patriarchs and the Anshei Knesset HaGedolah

Patriarchal Institution

The Talmud records a beautiful tradition about the origins of the three daily prayers:

"אַבְרָהָם תִּקֵּן תְּפִלַּת שַׁחֲרִית" — "Abraham instituted the morning prayer [Shacharit], as it is written: 'And Abraham arose early in the morning to the place where he had stood' — and standing refers only to prayer, as it is written: 'And Pinchas stood and prayed.'"

[Berakhot 26b]

The same passage teaches that Isaac instituted Mincha (afternoon prayer) and Jacob instituted Maariv (evening prayer).

Formal Codification

While the Patriarchs established the concept of the three daily prayers, the Amidah's specific blessings were formally arranged by the Men of the Great Assembly (Anshei Knesset HaGedolah) in the early Second Temple period. This is a key distinction — the times of prayer are patriarchal; the structured text is rabbinic.

The Nineteen Blessings

The Amidah is divided into three sections:

1. Praise (Blessings 1–3)

Avot — God of the Patriarchs
Gevurot — God's might (including revival of the dead)
Kedushah — God's holiness

2. Petitions (Blessings 4–16)

These include requests for wisdom, repentance, forgiveness, redemption, health, prosperity, ingathering of exiles, restoration of justice, and the rebuilding of Jerusalem.

On Shabbat and Yom Tov, the thirteen middle blessings are replaced by a single blessing appropriate to the day, as requests are considered inappropriate on the day of rest.

3. Thanksgiving (Blessings 17–19)

Avodah — restoration of Temple service
Hoda'ah — thanksgiving (Modim)
Birkat Shalom — blessing for peace

Special Insertions: Al HaNissim

On Chanukah and Purim, the prayer Al HaNissim ("For the Miracles") is inserted into the Hoda'ah (thanksgiving) blessing. The Chanukah version reads:

"בִּימֵי מַתִּתְיָהוּ בֶּן יוֹחָנָן כֹּהֵן גָּדוֹל חַשְׁמוֹנָאִי וּבָנָיו כְּשֶׁעָמְדָה מַלְכוּת יָוָן הָרְשָׁעָה עַל עַמְּךָ יִשְׂרָאֵל... מָסַרְתָּ גִבּוֹרִים בְּיַד חַלָּשִׁים וְרַבִּים בְּיַד מְעַטִּים" "In the days of Mattityahu son of Yochanan the High Priest... when the wicked Greek kingdom rose against Your people Israel... You delivered the mighty into the hands of the weak, and the many into the hands of the few."

[Siddur Ashkenaz, Amidah, Hoda'ah; Birkat Hamazon, Blessing on the Land]

This insertion is made both in the Amidah and in Birkat Hamazon (Grace After Meals).

Laws of Recitation

Key halachot (laws) governing the Amidah include:

Standing with feet together, facing Jerusalem (and, by extension, the Temple Mount).
Silent recitation — the prayer is whispered, audible only to oneself.
Kavvanah (intention) — one must have at minimum the intention that one is standing before God.
No interruption — one may not speak, gesture, or pause during recitation.
The chazan (prayer leader) repeats the Amidah aloud (chazarat hashatz) to fulfill the obligation for those who cannot pray on their own.

Connection to the Verse in Deuteronomy

The Talmud derives the obligation of daily prayer from the verse:

"וּלְעׇבְד֔וֹ בְּכׇל־לְבַבְכֶ֖ם" — "And to serve Him with all your heart" [Deuteronomy 11:13]

The Sifrei interprets "service of the heart" as referring specifically to tefillah — prayer. This grounds the Amidah not merely as rabbinic ordinance but as an expression of the Torah's deepest demand: total, heartfelt devotion to God.
