Revelation 9:18

And the first sounded, and there came hail and fire, mixed with blood, and they were thrown to the earth; and a third of the earth was burned up, and a third of the trees were burned up, and all the green grass was burned up.

And the second angel sounded, and something like a great mountain burning with fire was thrown into the sea; and a third of the sea became blood,

and a third of the creatures which were in the sea—those which had life—died; and a third of the ships were destroyed.

And the third angel sounded, and a great star fell from heaven, burning like a torch, and it fell on a third of the rivers and on the springs of waters.

And the name of the star is called Wormwood; and a third of the waters became wormwood, and many men died from the waters, because they were made bitter.

And the fourth angel sounded, and a third of the sun and a third of the moon and a third of the stars were struck, so that a third of them would be darkened and the day would not shine for a third of it, and the night in the same way.

And the four angels were released, who had been prepared for the hour and day and month and year, so that they would kill a third of mankind.

And this is how I saw in the vision the horses and those who sit on them: the riders had breastplates the color of fire and of hyacinth and of brimstone; and the heads of the horses are like the heads of lions; and out of their mouths come fire and smoke and brimstone.

And if anyone wishes to harm them, fire comes out of their mouth and devours their enemies; so if anyone wishes to harm them, he must be killed in this way.
