Hebrew names the synagogue in three ways that together describe its full range of functions: beit tefillah, a house of prayer, beit midrash, a house of study, and beit knesset, a house of assembly, and a functioning synagogue is expected to serve all three, hosting not only services but Torah study sessions, communal meetings and life cycle events such as weddings and bar and bat mitzvah ceremonies. Public prayer requiring the recitation of certain key texts traditionally requires a minyan, a quorum of ten adult Jews, reflecting Judaism's emphasis on communal rather than purely private worship for its central liturgical moments, though the definition of who counts toward a minyan differs between denominations.
The Torah service forms the liturgical center of Sabbath and festival worship, the scroll carried in procession from the ark to the bimah, read aloud according to a fixed annual or triennial cycle, and returned to the ark at the service's conclusion, a sequence that gives the physical relationship between ark and bimah its lasting importance regardless of a synagogue's particular architectural style. Beyond scheduled services, a synagogue commonly houses a rabbi's study, classrooms for religious education, and administrative offices, functioning as a diaspora community's central institution in a way that extends well past the hours of formal prayer.
