Some further notes:
The 'seven times of Daniel' has no bearing on the prophecies of Jesus, because they were fulfilled in Nebuchadnezzar. Any 'second fulfillment' is purely a speculative extra-biblical doctrine.
"But whenever they persecute you in one city, flee to the next; for truly I say to you, you will not finish going through the cities of Israel until the Son of Man comes." - Matthew 10:23 (NASB)
Mark 13:24-27, 29-30:
"But in those days, after the tribulation, THE SUN WILL BE DARKENED AND THE MOON WILL NOT GIVE ITS LIGHT. AND THE STARS WILL BE FALLING from heaven, and the powers that are in the heavens will be shaken. Then they will see THE SON OF MAN COMING IN CLOUDS with great power and glory. And then He will send forth the angels, and will gather together His elect from the four winds, from the farthest end of the earth to the farthest end of heaven." "Even so, you too, when you see these things happening, recognize that He is near, right at the door. Truly I say to you, this generation will not pass away until all these things take place."
Ezekiel 32:7-8 (NASB), concerning Egypt:
"'And when I extinguish you, I will cover the heavens and darken their stars; I WILL COVER THE SUN WITH A CLOUD, AND THE MOON WILL NOT GIVE ITS LIGHT. All the shining lights in the heavens I will darken over you, and will set darkness on your land,' Declares the Lord God."
In Isaiah 13:9-11 (NASB), concerning the laying to waste of Babylon:
"Behold, the day of the Lord is coming, cruel, with fury and burning anger, to make the land a desolation; and He will exterminate its sinners from it. For the stars of heaven and their constellations will not flash forth their light; THE SUN WILL BE DARK WHEN IT RISES AND THE MOON WILL NOT SHED ITS LIGHT. Thus I will punish the world for its evil and the wicked for their iniquity; I will also put an end to the arrogance of the proud and abase the haughtiness of the ruthless."
Extract from Barnes Notes on verse 10:
"This verse cannot be understood literally, but is a metaphorical representation of the calamities that were coming upon Babylon. The meaning of the figure evidently is, that those calamiities would be such as would be appropriately denoted by the sudden extinguishment of the stars, the sun, and the moon. As nothing would tend more to anarchy, distress, and ruin, than thus to have all the lights of heaven suddenly and forever quenched, this was an apt and forcible representation of the awful calamities that were coming upon the people. Darkness and night, in the Scriptures, are often the emblem of calamity and distress (see the note at Matthew 24:29). The revolutions and destructions of kingdoms and nations are often represented in the Scriptures under this image."
Extract from Barnes Notes on verse 11:
"By the 'world' here is evidently meant the Babylonian empire, in the same way as 'all the world' in Luke 2:1, means Judea; and in Acts 11:28, means the Roman empire. Babylonia, or Chaldea, was the most mighty empire then on earth, and might be said to comprehend the whole world."
