Revelation 9:7-11

7The appearance of the locusts was like horses prepared for battle. Something like golden crowns was on their heads; their faces were like human faces;

8they had hair like women’s hair; their teeth were like lions’ teeth;

9they had chests like iron breastplates; the sound of their wings was like the sound of many chariots with horses rushing into battle;

10and they had tails with stingers like scorpions, so that with their tails they had the power to harm people for five months.

11They had as their king the angel of the abyss; his name in Hebrew is Abaddon, and in Greek he has the name Apollyon.
