Zechariah 14:4-11 NASB
4 In that day His feet will stand on the Mount of Olives, which is in front of Jerusalem on the east; and the Mount of Olives will be split in its middle from east to west by a very large valley, so that half of the mountain will move toward the north and the other half toward the south.
5 You will flee by the valley of My mountains, for the valley of the mountains will reach to Azel; yes, you will flee just as you fled before the earthquake in the days of Uzziah king of Judah. Then the LORD, my God, will come, and all the holy ones with Him!
6 In that day there will be no light; the luminaries will dwindle.
7 For it will be a unique day which is known to the LORD, neither day nor night, but it will come about that at evening time there will be light.
8 And in that day living waters will flow out of Jerusalem, half of them toward the eastern sea and the other half toward the western sea; it will be in summer as well as in winter.
9 And the LORD will be king over all the earth; in that day the LORD will be the only one, and His name the only one.
10 All the land will be changed into a plain from Geba to Rimmon south of Jerusalem; but Jerusalem will rise and remain on its site from Benjamin's Gate as far as the place of the First Gate to the Corner Gate, and from the Tower of Hananel to the king's wine presses.
11 People will live in it, and there will no longer be a curse, for Jerusalem will dwell in security.
Malachi 3:2-6 NASB
"But who can endure the day of His coming? And who can stand when He appears? For He is like a refiner's fire and like fullers' soap. He will sit as a smelter and purifier of silver, and He will purify the sons of Levi and refine them like gold and silver, so that they may present to the LORD offerings in righteousness. Then the offering of Judah and Jerusalem will be pleasing to the LORD as in the days of old and as in former years. "Then I will draw near to you for judgment; and I will be a swift witness against the sorcerers and against the adulterers and against those who swear falsely, and against those who oppress the wage earner in his wages, the widow and the orphan, and those who turn aside the alien and do not fear Me," says the L ord of hosts. "For I, the LORD, do not change; therefore you, O sons of Jacob, are not consumed.
Matthew 24:29-31 NASB95
"But immediately after the tribulation of those days THE SUN WILL BE DARKENED, AND THE MOON WILL NOT GIVE ITS LIGHT, AND THE STARS WILL FALL from the sky, and the powers of the heavens will be shaken. "And then the sign of the Son of Man will appear in the sky, and then all the tribes of the earth will mourn, and they will see the SON OF MAN COMING ON THE CLOUDS OF THE SKY with power and great glory. "And He will send forth His angels with A GREAT TRUMPET and THEY WILL GATHER TOGETHER His elect from the four winds, from one end of the sky to the other.
2 Thessalonians 1:9-10 NASB95
These will pay the penalty of eternal destruction, away from the presence of the Lord and from the glory of His power, when He comes to be glorified in His saints on that day, and to be marveled at among all who have believed--for our testimony to you was believed.
(v 7 says this happens "when(lit: at the revelation of the Lord Jesus) the Lord Jesus will be revealed from heaven with His mighty angels in flaming fire,")
