Revelation 8:10-12

10The third angel sounded [his trumpet], and a great star fell from heaven, burning like a torch [flashing across the sky], and it fell on a third of the rivers and on the springs of [fresh] waters.

11The name of the star is Wormwood; and a third of the waters became wormwood, and many people died from the waters, because they had become bitter (toxic).

12Then the fourth angel sounded [his trumpet], 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 a third of the daylight would not shine, and the night in the same way [would not shine].
