Minyan
A minyan is a quorum of ten Jewish adults – in traditional Orthodox communities, ten males, and in more progressive communities, ten people – required to recite specific public prayers and for other religious purposes. The Talmud derives this concept from the story of the spies and elsewhere mentions the books of Ruth and Psalms as sources of the requirement for a minyan in particular circumstances.
