Zechariah is the eleventh of the Minor Prophets. He lived at about the same time as Haggai. We know this by the content of their writings and by the fact they are both mentioned by Ezra (Ezra 5:1, 6:14).
Haggai was concerned with restoration and being about the Lord’s business. Zechariah has a much longer list of concerns. Essentially picking up where Haggai leaves off, Zechariah calls for repentance, sincerity, and purification. Zechariah also contains numerous messianic and apocalyptic prophecies. Where Haggai was primarily concerned with messages to the present audience, Zechariah seems to write more for the sake of a future audience.
The book of Zechariah is one of the more lengthy of the Minors, however it is easy to break into small pieces. Much of Zechariah is a record of brief individual visions. Although it includes judgments, it also is great source of hope for the faithful. Zechariah is heavily quoted in the New Testament, especially in John’s Revelation.
Zechariah the Prophet
Zech 1:1 In the eighth month of Darius' second year, the word of the LORD came to the prophet Zechariah, son of Berechiah son of Iddo, as follows: [NET]
This passage dates the start of the book to November of 520 BC. Iddo was a priest mentioned in Neh 12:4 who migrated back to Jerusalem from Babylon about 538 BC. Zechariah would have been raised to be a priest. He was probably a relatively young man just 18 years after the family returned from Babylon. The Temple rebuilding project began in 536 BC, however the project soon stalled. No more work was done until 520 BC when Zechariah and Haggai began pressing the king and people to get back to the task. The Temple was finished in 516 BC.
