What is the Aleinu prayer?

The Aleinu (עָלֵינוּ) prayer is one of the most important and ancient prayers in Jewish liturgy, recited at the conclusion of every prayer service — Shacharit (morning), Mincha (afternoon), and Maariv (evening). It proclaims God's sovereignty over all creation and expresses the Jewish people's unique covenantal mission, while looking forward to the ultimate tikkun olam (repair of the world) when all humanity will recognize God's kingship.

Key Takeaways

Aleinu is recited standing at the end of all three daily prayer services, as well as during the Musaf of Rosh Hashanah.
The prayer has two parts: the first acknowledges Israel's distinct spiritual calling; the second expresses the universal hope for God's kingdom over all humanity.
The Shulchan Arukh rules it must be recited with kavana (intention and focus).
On Rosh Hashanah and Yom Kippur, it is customary to fully prostrate oneself (hishtachavaya) during Aleinu.
The prayer is traditionally attributed to Joshua or to Rav (the 3rd-century Babylonian Amora), though its origins are debated.

The Text of Aleinu

The first paragraph opens:

עָלֵינוּ לְשַׁבֵּחַ לַאֲדוֹן הַכֹּל לָתֵת גְּדֻלָּה לְיוֹצֵר בְּרֵאשִׁית "It is our duty to praise the Master of all, to ascribe greatness to the Author of creation..."

It continues by noting that Israel was not made like the nations:

שֶׁלֹּא עָשָׂנוּ כְּגוֹיֵי הָאֲרָצוֹת וְלֹא שָׂמָנוּ כְּמִשְׁפְּחוֹת הָאֲדָמָה "Who has not made us like the nations of the lands, nor placed us like the families of the earth..."

The contrast is then drawn:

שֶׁהֵם מִשְׁתַּחֲוִים לַהֶבֶל וָרִיק... וַאֲנַחְנוּ כּוֹרְעִים וּמִשְׁתַּחֲוִים וּמוֹדִים לִפְנֵי מֶלֶךְ מַלְכֵי הַמְּלָכִים הַקָּדוֹשׁ בָּרוּךְ הוּא "They bow to vanity and emptiness... but we kneel and bow and give thanks before the King of kings, the Holy One, Blessed be He."

[Siddur Ashkenaz, Weekday Shacharit, Aleinu 1]

Structure: Two Paragraphs

Part One — Aleinu (Our Duty)

The first paragraph focuses on particularism — Israel's unique relationship with God and its calling to serve Him. This is not a statement of superiority but of responsibility: Israel was chosen for a specific covenantal role.

Part Two — V'Al Ken (Therefore We Hope)

The second paragraph, beginning וְעַל כֵּן נְקַוֶּה ("Therefore we hope"), shifts to a universalist vision — the prayer that all nations will eventually recognize God's sovereignty, that idolatry will be abolished, and that the world will be perfected under God's kingdom. This section includes the phrase l'takken olam b'malchut Shaddai (to repair the world under God's sovereignty), the origin of the concept of tikkun olam.

Halachic Requirements

The Shulchan Arukh [Orach Chayim 132:2] rules:

וְאוֹמְרִים אַחַר סִיּוּם הַתְּפִלָּה: עָלֵינוּ לְשַׁבֵּחַ, מְעֻמָּד; וְיִזָּהֵר לְאָמְרוֹ בְּכַוָּנָה "After the conclusion of prayer, Aleinu is recited while standing, and one should take care to say it with kavana (intention)."

The Rama (R. Moshe Isserles) adds in the same passage that one should pause slightly before saying "va'anachnu kor'im" ("but we kneel") to create a clear contrast with the preceding phrase about idol worshippers.

Prostration on Rosh Hashanah and Yom Kippur

On the High Holy Days, Aleinu takes on special prominence. The Shulchan Arukh [Orach Chayim 621:4] records:

It is customary to fully prostrate (nafilu al paneihem) during the Aleinu of the Musaf service on Rosh Hashanah and Yom Kippur, in a manner not done throughout the rest of the year.

[Shulchan Arukh, Orach Chayim 621:4]

This full prostration (hishtachavaya) is a rare practice in normative Jewish worship, preserved specifically for these solemn moments.

Origins of the Prayer

The Talmud [Rosh Hashanah 32b] associates Aleinu with Rav (Abba Arikha, 3rd century Babylon), who composed it for the Malkhuyot (Kingship) section of the Rosh Hashanah Musaf service.
A popular tradition attributed it to Joshua upon entering the Land of Israel, seeing the Israelites encamped tribe by tribe (based on thematic parallels to Numbers 24:2).
Over time, it migrated from the High Holy Day Musaf to the conclusion of all daily services — a testament to its theological centrality.

Theological Significance

Aleinu beautifully holds two complementary truths in tension:

Jewish particularity — the Jewish people have a specific mission and covenant with God.
Universal destiny — the ultimate goal is not Jewish exclusivity but the recognition of God by all humanity.

This is why Aleinu serves as the perfect closing prayer: it grounds the worshipper in their identity while pointing toward redemption for the entire world.
