¹ sn Darius is Darius Hystaspes, king of Persia from 522-486 b.c.

² sn The eighth month of Darius’ second year was late October – late November, 520 b.c., by the modern (Julian) calendar. This is two months later than the date of Haggai’s first message to the same community (cf. Hag 1:1).

³ sn Both Ezra (5:1; 6:14) and Nehemiah (12:16) speak of Zechariah as a son of Iddo only. A probable explanation is that Zechariah’s actual father Berechiah had died and the prophet was raised by his grandfather Iddo. The “Zechariah son of Barachiah” of whom Jesus spoke (Matt 23:35; Luke 11:51) was probably the martyred prophet by that name who may have been a grandson of the priest Jehoiada (2 Chr 24:20-22).

⁴ sn The fourth day of Kislev, the ninth month would be December 7, 518 b.c., 22 months after the previous eight visions.

⁵ sn Zechariah is only dramatizing what God had done historically (see the note on the word “cedars” in 11:1). The “one month” probably means just any short period of time in which three kings ruled in succession. Likely candidates are Elah, Zimri, Tibni (1 Kgs 16:8-20); Zechariah, Shallum, Menahem (2 Kgs 15:8-16); or Jehoiakim, Jehoiachin, Zedekiah (2 Kgs 24:1–25:7).
