A solemn festival of the Jews; -- so called because
   celebrated on the fiftieth day (seven weeks) after the second day of
   the Passover (which fell on the sixteenth of the Jewish month Nisan);
   -- hence called, also, the Feast of Weeks. At this festival an offering
   of the first fruits of the harvest was made. By the Jews it was
   generally regarded as commemorative of the gift of the law on the
   fiftieth day after the departure from Egypt.
