Pur, Purim: a lot, lots, a festival instituted by the Jews (Esther 9:24-32) in ironical commemoration of Haman's consultation of the Pur (a Persian word), for the purpose of ascertaining the auspicious day for executing his cruel plot against their nation. It became a national institution by the common consent of the Jews, and is observed by them to the present day, on the 14th and 15th of the month Adar, a month before the Passover.
