King Darius Hystaspis came to the throne ca. 520 B.C.E. Earlier, in 538 B.C.E., Cyrus II had issued a proclamation to the Jews of his empire permitting them to return to Israel and rebuild the Temple. At that time Zerubbabel, a descendant of King David, and Joshua, the High Priest, led 42,360 Israelites, 7,337 servants, and 200 singing men and women back to the land (according to Ezra 2). That Haggai gives this prophecy in 520 seems to confirm that the Second Temple had not yet been built some 18 years after the first wave of return by the exiles.
(14) Then the LORD roused the spirit of Zerubbabel son of Shealtiel, the governor of Judah, and the spirit of the high priest Joshua son of Jehozadak, and the spirit of all the rest of the people: They came and set to work on the House of the LORD of Hosts, their God, (15) on the twenty-fourth day of the sixth month. In the second year of King Darius, (1) on the twenty-first day of the seventh month, the word of the LORD came through the prophet Haggai:
24th day of the 6th month = 24 Elul. 21st day of 7th month = 21 Tishrei (end of Sukkot)
(1) In the eighth month of the second year of Darius, this word of the LORD came to the prophet Zechariah son of Berechiah son of Iddo:
Zechariah begins his career as a Prophet two months after the Prophet Haggai (see above), in the year 520 B.C.E. According to the Masoretic accentuation the title "Prophet" is attached to Iddo and not Zechariah. The book is eight chapters long and has three subunits.
After this opening oracle there are eight visions, which make up the bulk of the first half of the book concluding in chapter six.
(8) In the night, I had a vision. I saw a man, mounted on a bay horse, standing among the myrtles in the Deep, and behind him were bay, sorrel, and white horses. (9) I asked, “What are those, my lord?” And the angel who talked with me answered, “I will let you know what they are.” (10) Then the man who was standing among the myrtles spoke up and said, “These were sent out by the LORD to roam the earth.” (11) And in fact, they reported to the angel of the LORD who was standing among the myrtles, “We have roamed the earth, and have found all the earth dwelling in tranquility.” (12) Thereupon the angel of the LORD exclaimed, “O LORD of Hosts! How long will You withhold pardon from Jerusalem and the towns of Judah, which You placed under a curse seventy years ago?” (13) The LORD replied with kind, comforting words to the angel who talked with me. (14) Then the angel who talked with me said to me: “Proclaim! Thus said the LORD of Hosts: I am very jealous for Jerusalem—for Zion— (15) and I am very angry with those nations that are at ease; for I was only angry a little, but they overdid the punishment. (16) Assuredly, thus said the LORD: I graciously return to Jerusalem. My House shall be built in her—declares the LORD of Hosts—the measuring line is being applied to Jerusalem. (17) Proclaim further: Thus said the LORD of Hosts: My towns shall yet overflow with bounty. For the LORD will again comfort Zion; He will choose Jerusalem again.”
This passage can be dated to 518 B.C.E. and is an inquiry by the priests at Beth El whether they should continue to fast on Tisha B'Av and Tzom Gedalliah.
Zechariah 9-11 is a collection of oracles that have a very diverse period of dating - from the mid 8th century B.C.E. all the way tot he Seleucid rule in the 3rd century B.C.E.
This oracle presents Jerusalem as the focal point of the future cosmic/Messianic battle to come.
Chapter 14 is read as the Haftarah for the 1st day of Sukkot.
Malachi's themes continue that of Haggai and Zechariah and is dated from that time period. While Haggai anticipates the rebuilding of the Temple and Zechariah deals with the rebuilding and the sanctity of the Temple, Malachi seems to consider the rebuilding a matter of the past and focuses on the perversion of rites performed there (from JPS Bible Commentary: Haftarot). The name "Malachi" means "My Messenger". Although the Talmud ascribes this book to Ezra or Mordechai, it is probably an anonymous Prophet of Israel known simply by the name Malachi.
A condemnation against the priests who "scorn" God's name through perversion of the sacrifices.
A condemnation of the people for their ritual improprieties.
Condemnation of intermarriage with foreign women.
God will reject the people's offerings because they have broken faith with the "covenanted spouse" to chase after foreign wives.
A criticism of the people for wearying God with impious talk and questioning God's will to justice.
God will send an "Angel of the covenant" who will bring sinners to justice and act as a purifying fire and cleansing lye so that the offerings of the people will once again by pleasing to the Lord.
[הנה אנכי שלח לכם את אליה הנביא לפני בוא יום ה' הגדול והנורא]
The book concludes with a reprise of the theme of a coming day of judgment and a call to observe the Torah of Moses. God will send Elijah to reconcile parents and children, which will prevent an "utter destruction".
