9 Their chests were covered with something that looked like armor made out of iron. The sound of their wings was like the thundering of many horses and chariots rushing into battle.
10 They had tails and stings like scorpions. And in their tails they had power to hurt people over and over for five months.
11 Their king was the angel of the Abyss. In the Hebrew language his name is Abaddon. In Greek it is Apollyon.
12 The first terrible judgment is past. Two others are still coming.
13 The sixth angel blew his trumpet. Then I heard a voice coming from the corners of the golden altar that stands in front of God.
14 The voice spoke to the sixth angel who had the trumpet. It said, "Set the four angels free who are held at the great river Euphrates."
15 The four angels had been ready for this very hour and day and month and year. They were set free to kill a third of all people.
