Zechariah 13:8

and I will purge from you the rebels and those who transgress against Me; I will bring them out of the land where they sojourn, but they will not enter the land of Israel. Thus you will know that I am Yahweh.

“All the sinners of My people will die by the sword, Those who say, ‘The calamity will not overtake or confront us.’

“But I will cause to remain in your midst A lowly and poor people, And they will take refuge in the name of Yahweh.

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.
