Revelation 8:10-12

New Revised Standard Version Catholic Edition

¹⁰ The third angel blew his trumpet, and a great star fell from heaven, blazing like a torch, and it fell on a third of the rivers and on the springs of water. ¹¹ The name of the star is Wormwood. A third of the waters became wormwood, and many died from the water, because it was made bitter.

¹² The fourth angel blew his trumpet, and a third of the sun was struck, and a third of the moon, and a third of the stars, so that a third of their light was darkened; a third of the day was kept from shining, and likewise the night.
