It is a custom among religious Jewish communities for a weekly Torah portion to be read during Jewish prayer services on Monday, Thursday, and Saturday. The full name, Parashat HaShavua (Hebrew: פָּרָשַׁת הַשָּׁבוּעַ), is popularly abbreviated to parashah (also parshah /pɑːrʃə/ or parsha), and is also known as a Sidra or Sedra /sɛdrə/.
The parashah is a section of the Torah (Five Books of Moses) used in Jewish liturgy during a particular week. There are 54 parshas, or parashiyot in Hebrew, and the full cycle is read over the course of one Biblical year.
