Wise Men
    n 1: (New Testament) the sages who visited Jesus and Mary and
         Joseph shortly after Jesus was born; the Gospel According
         to Matthew says they were guided by a star and brought
         gifts of gold and frankincense and myrrh; because there
         were three gifts it is usually assumed that there were
         three of them [syn: Wise Men, Magi]

Easton's 1897 Bible Dictionary:

Wise men
   mentioned in Dan. 2:12 included three classes, (1) astrologers,
   (2) Chaldeans, and (3) soothsayers. The word in the original
   (hakamim) probably means "medicine men. In Chaldea medicine was
   only a branch of magic. The "wise men" of Matt. 2:7, who came
   from the East to Jerusalem, were magi from Persia or Arabia.
