3rd Trumpet Wormwood

God says: "I myself will feed them "Wormwood".

10 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; 11 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. Men will call this "Wormwood" because it will poision the waters with radiation.

A GREAT STAR could be non other than the Angel of the Lord Himself.
