The Masoretes (Hebrew: , ba'alei hamasorah) were groups of Jewish scribe-scholars who worked between the 6th and 10th centuries CE, based primarily in present-day Israel in the cities of Tiberias and Jerusalem, as well as in Iraq (Babylonia). Each group compiled a system of pronunciation and grammatical guides in the form of diacritical notes on the external form of the biblical text in an attempt to standardize the pronunciation, paragraph and verse divisions and cantillation of the Jewish Bible, the Tanakh, for the worldwide Jewish community.
