The word torah or "teaching" refers in particular to the first five books of the Bible. For ceremonial reading, these are handwritten on parchment in a scroll. Each week on Sabbath Jews read a section, completing the Torah in a year. A part of the weekly section is also read on Mondays and Thursdays. In Orthodox Judaism, a quorum of ten Jewish men (a minyan) is required for the ceremonial, public reading. Reform and some Conservative Jews do not discriminate between the sexes in matters of ritual, but these movements are small in Israel.
