August-December 520 B.C. Haggai & Zechariah's Messages

August-December 520 B.C.  Haggai delivers his messages.  Zechariah is dated to this period also.  See “Introducation” in both books in The New Geneva Study Bible,  (Nashville: Thomas Nelson Publishers, 1995).  We would also commend Leviticus 1-7, 16, & 23 for review of the sacrifices and feast days, e.g. Day of Atonement.
