“In the eighth month,

In the second year

Of King Darius,

The word of Yahweh

Came to the prophet Zechariah,

The son of Berechiah,

The son of Iddo.”

The word of Yahweh came to the prophet Zechariah in the same year as it had come to Haggai, the second year of Persian King Darius I in 520 BCE.  However, this was the 8^th month and not the 6^th month as with Haggai, so that it was 2 month later.  Zechariah was the son of Berechiah and the grandson of Iddo.  In the Book of Ezra, chapter 5, there is an explicit mention of Haggai and Zechariah, the son of Iddo.  Nehemiah, chapter 12, mentioned Iddo as one of the high priests who came with Zerubbabel when he left Babylon in 538 BCE.  Thus, Iddo would have been an important person.  Berechiah seemed to be less important, but could be the father of the young Zechariah.  Nehemiah mentioned Berechiah as the son of Meshezabel, in chapter 3.
