And the first sounded, and there followed hail and fire, mingled with blood, and they were cast upon the earth: and the third part of the earth was burnt up, and the third part of the trees was burnt up, and all green grass was burnt up.

Revelation:8.7

And the second angel sounded, and as it were a great mountain burning with fire was cast into the sea: and the third part of the sea became blood

and there died the third part of the creatures which were in the sea, [even] they that had life; and the third part of the ships was destroyed.

Revelation:8.8-9

And the third angel sounded, and there fell from heaven a great star, burning as a torch, and it fell upon the third part of the rivers, and upon the fountains of the waters

and the name of the star is called Wormwood: and the third part of the waters became wormwood; and many men died of the waters, because they were made bitter

Revelation:8.10-11

The Lord is not slack concerning his promise, as some count slackness; but is longsuffering to you-ward, not wishing that any should perish, but that all should come to repentance

But the day of the Lord will come as a thief; in the which the heavens shall pass away with a great noise, and the elements shall be dissolved with fervent heat, and the earth and the works that are therein shall be burned up.

Seeing that these things are thus all to be dissolved, what manner of persons ought ye to be in [all] holy living and godliness

2Peeter:3.9-12
