Zech 12:1-11 Zechariah prophesies that, some time in the future, all the nations of the world will join forces to attack Jerusalem:
“At that time the LORD will protect the people in Jerusalem. Then even the weakest of them will be strong like David. And the family of David will be like God, like an angel of the LORD in front of them.” (Zechariah 12:8)

Zech 13:1-6 The LORD promises to purify Jerusalem from sin and idolatry:
"At that time a fountain will be open for David's descendents and for the people of Jerusalem to cleanse them of their sin and uncleanness... At that time I will get rid of the names of the idols from the land." (Zechariah 13:1-2)
Zech 13:7-9 The LORD authorises the killing of the worthless shepherd (the King of Judah) who abandoned God’s people (see Zechariah 11:15-17).
Zech 14:1-5 Zechariah prophesies that, when the ‘Day of Judgement’ approaches, Jerusalem will be attacked and looted. Half the population will be taken away as captives.
Then the LORD will stand on the Mount of Olives to the east of Jerusalem and an earthquake will form a new valley through which the remaining people will escape, "just as you ran from the earthquake when Uzziah was king of Judah." (Zechariah 14:5)
The Mount of Olives, Jerusalem (Yair Haklai)
Zech 14:6-21 On that day, "There will be no day or night; even at evening it will still be light." (Zechariah 14:6)
Fresh water will flow from Jerusalem, half to the Dead Sea and half to the Mediterranean (see Ezekiel 47:1-12 & Revelation 22:1-2). “Then the LORD will be king over the whole world. At that time there will be only one LORD, and his name will be the only name." (Zechariah 14:9)
"All the land south of Jerusalem from Geba to Rimmon will be turned into a plain. Jerusalem will be raised up, but it will stay in the same place... People will live there, and it will never be destroyed again." (Zechariah 14:10-11)
"But the LORD will bring a terrible disease on the nations that fought against Jerusalem. Their flesh will rot away while they are standing up." (Zechariah 14:12)
"All those left alive of the people who came to fight Jerusalem will come back to Jerusalem year after year to worship the King, the LORD All-powerful, and to celebrate the Feast of Shelters." (Zechariah 14:16) (See Major Jewish Religious Festivals.)
"At that time there will not be any buyers or sellers in the Temple of the LORD All-powerful." (Zechariah 14:21) In the New Testament, Jesus deliberately sets out to fulfil this prophesy (even if only for a short time) when he clears the Temple Courts of the money-changers and traders (see Mark 11:15-18).
