There will be famines and earthquakes in various places. All these are the beginning of birth pains.
I watched as he opened the sixth seal. There was a great earthquake. The sun turned black like sackcloth made of goat hair, the whole moon turned blood red, and the stars in the sky fell to earth, as late figs drop from a fig tree when shaken by a strong wind.
The sky receded like a scroll, rolling up, and every mountain and island was removed from its place.
Then the kings of the earth, the princes, the generals, the rich, the mighty, and every slave and every free man hid in caves and among the rocks of the mountains.
They called to the mountains and the rocks, “Fall on us and hide us from the face of him who sits on the throne and from the wrath of the Lamb! For the great day of their wrath has come, and who can stand?”
Then they heard a loud voice from heaven saying to them, “Come up here.” And they went up to heaven in a cloud, while their enemies looked on.
At that very hour there was a severe earthquake and a tenth of the city collapsed. Seven thousand people were killed in the earthquake, and the survivors were terrified and gave glory to the God of heaven.
The seventh angel poured out his bowl into the air, and out of the temple came a loud voice from the throne, saying, “It is done!”
Then there came flashes of lightning, rumblings, peals of thunder and a severe earthquake. No earthquake like it has ever occurred since man has been on earth, so tremendous was the quake.
The great city split into three parts, and the cities of the nations collapsed. God remembered Babylon the Great and gave her the cup filled with the wine of the fury of his wrath.
Every island fled away and the mountains could not be found.
The sixth angel sounded his trumpet, and I heard a voice coming from the horns of the golden altar that is before God.
It said to the sixth angel who had the trumpet, “Release the four angels who are bound at the great river Euphrates.”
And the four angels who had been kept ready for this very hour and day and month and year were released to kill a third of mankind.
The number of the mounted troops was two hundred million. I heard their number.
The horses and riders I saw in my vision looked like this: Their breastplates were fiery red, dark blue, and yellow as sulfur. The heads of the horses resembled the heads of lions, and out of their mouths came fire, smoke and sulfur.
A third of mankind was killed by the three plagues of fire, smoke and sulfur that came out of their mouths.
The power of the horses was in their mouths and in their tails; for their tails were like snakes, having heads with which they inflict injury.
The sixth angel poured out his bowl on the great river Euphrates, and its water was dried up to prepare the way for the kings from the East.
