Jewish prayer in the context of "Mussaf"

A Torah scroll (Hebrew: סֵפֶר תּוֹרָה, romanized: Sefer Torah, lit. 'Book of Torah'; pl. סִפְרֵי תוֹרָה, Sifrei Torah) is a handwritten copy of the Torah, meaning the five books of Moses (the first books of the Hebrew Bible). The Torah scroll is mainly used in the ritual of Torah reading during Jewish prayers. At other times, it is stored in the holiest spot within a synagogue, the Torah ark, which is usually an ornate curtained-off cabinet or section of the synagogue built along the wall that most closely faces Jerusalem, the direction Jews face when praying.

The text of the Torah is also commonly printed and bound in book form for non-ritual functions, called a Chumash (plural Chumashim; "five-part", for the five books of Moses), and is often accompanied by commentaries or translations.

Shema Yisrael (Shema Israel or Sh'ma Yisrael; Hebrew: שְׁמַע יִשְׂרָאֵל, lit. 'Hear, O Israel') is a Jewish prayer (known as the Shema) that serves as a centerpiece of the morning and evening Jewish prayer services. Its first verse, Deuteronomy 6:4, encapsulates the monotheistic essence of Judaism: "Hear, O Israel: YHWH our God, YHWH is one" (שְׁמַע יִשְׂרָאֵל יְהוָה אֱלֹהֵינוּ יְהוָה אֶחָֽד׃).

The first part can be translated as either "The LORD our God" or "The LORD is our God", and the second part as either "the LORD is one" or as "the one LORD" (in the sense of "the LORD alone"). Hebrew does not generally use a copula in the present tense, so translators must decide by inference which translation is appropriate in English. The word used for "the LORD" is the Tetragrammaton (YHWH).

A synagogue, or synagog also called a shul or a temple, is a place of worship for Jews and Samaritans. It serves as a house of prayer (with a main sanctuary and sometimes smaller chapels) where Jews attend religious services or ceremonies such as weddings, bar and bat mitzvahs, choir performances, and children's plays. Synagogues often also contain study rooms, social halls, administrative and charitable offices, classrooms for religious and Hebrew studies, and spaces for community gatherings. They frequently display commemorative, historic, or modern artwork alongside items of Jewish historical significance or exhibits about the synagogue itself.

Synagogues are buildings used for Jewish prayer, study, assembly, and reading of the Torah. The Torah (Pentateuch or Five Books of Moses) is traditionally read in its entirety over a period of a year in weekly portions during services, or in some synagogues on a triennial cycle. However, the edifice of a synagogue as such is not essential for holding Jewish worship. Halakha (Jewish law from the Mishnah – the "Oral Torah") states that communal Jewish worship can be carried out wherever a minyan, a group of at least 10 Jewish adult men, is assembled, often (but not necessarily) led by a rabbi. This minyan is the essence of Jewish communal worship, which can also be conducted alone or with fewer than ten people, but that excludes certain prayers as well as communal Torah reading. In terms of its specific ritual and liturgical functions, the synagogue does not replace the long-destroyed Temple in Jerusalem.

Lashon Hakodesh (Hebrew: לָשׁוֹן הַקֹּדֶשׁ; lit. "the tongue [of] holiness" or "the Holy Tongue"), also spelled L'shon Hakodesh or Leshon Hakodesh (Hebrew: לְשׁוֹן הַקֹּדֶשׁ), is a Jewish term and appellation attributed to the Hebrew language, or sometimes to a mix of Hebrew and Aramaic, in which its religious texts and prayers were written, and served, during the Medieval Hebrew era, for religious purposes, liturgy and Halakha – in contrary to the secular tongue, which served for the routine daily needs, such as the Yiddish or Ladino languages.

Mizrah (also spelled Mizrach, Mizrakh) (Hebrew: מִזְרָח, romanized: mīzrāḥ) is the "east" and the direction that Jews in the Diaspora west of Israel face during prayer. Practically speaking, Jews face the city of Jerusalem when praying, and those north, east, or south of Jerusalem face south, west, and north respectively.

In European and Mediterranean communities west of the Holy Land, mizrah also refers to the wall of the synagogue that faces east, where seats are reserved for the rabbi and other dignitaries. In addition, mizrah refers to an ornamental wall plaque used to indicate the direction of prayer in Jewish homes.

Shacharit [ʃaχaˈʁit] (Hebrew: שַחֲרִית šaḥăriṯ), or Shacharis in Ashkenazi Hebrew, is the morning tefillah (prayer) of Judaism, one of the three daily prayers.

Different traditions identify different primary components of Shacharit. Essentially all agree that pesukei dezimra, the Shema Yisrael and its blessings, and the Amidah are major sections. Some identify the preliminary blessings and readings, as a first, distinct section. Others say that Tachanun is a separate section, as well as the concluding blessings. On certain days, there are additional prayers and services added to shacharit, including Mussaf and a Torah reading.

Ashkenazi Hebrew (Hebrew: הֲגִיָּה אַשְׁכְּנַזִּית, romanized: hagiyoh ashkenazis, Yiddish: אַשכּנזישע הבֿרה, romanized: ashkenazishe havore) is the pronunciation system for Biblical and Mishnaic Hebrew favored for Jewish liturgical use and Torah study by Ashkenazi Jewish practice.
