Book of Zechariah in Wikipedia
            The Book of Zechariah is a book of the Hebrew Bible attributed 
to the prophet Zechariah. Zechariah’s ministry took place 
during the reign of Darius the Great (Zechariah 1:1 ), and was

visionary works of Zechariah 1-8.[2] Zechariah is specific 
about dating his writing (520-518 BC)...
