Zechariah 13:9

“But He knows the way I take; When He has tested me, I shall come forth as gold.

You have tested my heart; You have visited me by night; You have tried me and You find nothing; I have purposed that my mouth will not transgress.

Call upon Me in the day of distress; I shall rescue you, and you will glorify Me.”

For You have tested us, O God; You have refined us as silver is refined.

“Thus says Yahweh, the God of Israel, ‘Like these good figs, so I will recognize as good the exiles of Judah, whom I have sent out of this place into the land of the Chaldeans.

‘You shall be My people, And I will be your God.’”

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.

“And some of those who have insight will fall, in order to refine, purge, and make them pure until the time of the end, because it is still to come at the appointed time.

“Many will be purged, purified, and refined, but the wicked will act wickedly; and none of the wicked will understand, but those who have insight will understand.

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

“I will make the house of Judah mighty, And I will save the house of Joseph, And I will cause them to return, Because I have had compassion on them; And they will be as though I had not rejected them, For I am Yahweh their God, and I will answer them.

“But who can endure the day of His coming? And who can stand when He appears? For He is like a smelter’s fire and like fullers’ soap.

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.
