and the third part of the sun
And the fourth angel poured out his vial upon the sun; and power was given unto him to scorch men with fire.
And men were scorched with great heat, and blasphemed the name of God, which hath power over these plagues: and they repented not to give him glory.
For the stars of heaven and the constellations thereof shall not give their light: the sun shall be darkened in his going forth, and the moon shall not cause her light to shine.
Then the moon shall be confounded, and the sun ashamed, when the LORD of hosts shall reign in mount Zion, and in Jerusalem, and before his ancients gloriously.
I beheld the earth, and, lo, it was without form, and void; and the heavens, and they had no light.
And when I shall put thee out, I will cover the heaven, and make the stars thereof dark; I will cover the sun with a cloud, and the moon shall not give her light.
All the bright lights of heaven will I make dark over thee, and set darkness upon thy land, saith the Lord GOD.
The earth shall quake before them; the heavens shall tremble: the sun and the moon shall be dark, and the stars shall withdraw their shining:
The sun shall be turned into darkness, and the moon into blood, before the great and the terrible day of the LORD come.
And it shall come to pass in that day, saith the Lord GOD, that I will cause the sun to go down at noon, and I will darken the earth in the clear day:
Immediately after the tribulation of those days shall the sun be darkened, and the moon shall not give her light, and the stars shall fall from heaven, and the powers of the heavens shall be shaken:
Now from the sixth hour there was darkness over all the land unto the ninth hour.
But in those days, after that tribulation, the sun shall be darkened, and the moon shall not give her light,
And when the sixth hour was come, there was darkness over the whole land until the ninth hour.
And there shall be signs in the sun, and in the moon, and in the stars; and upon the earth distress of nations, with perplexity; the sea and the waves roaring;
And it was about the sixth hour, and there was a darkness over all the earth until the ninth hour.
And the sun was darkened, and the veil of the temple was rent in the midst.
The sun shall be turned into darkness, and the moon into blood, before that great and notable day of the Lord come:
and the day
And the LORD said unto Moses, Stretch out thine hand toward heaven, that there may be darkness over the land of Egypt, even darkness which may be felt.
And Moses stretched forth his hand toward heaven; and there was a thick darkness in all the land of Egypt three days:
They saw not one another, neither rose any from his place for three days: but all the children of Israel had light in their dwellings.
2 Corinthians 4:4
In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.
2 Thessalonians 2:9-12
Even him, whose coming is after the working of Satan with all power and signs and lying wonders,
And with all deceivableness of unrighteousness in them that perish; because they received not the love of the truth, that they might be saved.
And for this cause God shall send them strong delusion, that they should believe a lie:
That they all might be damned who believed not the truth, but had pleasure in unrighteousness.
