Revelation 9:7-11
7 The locusts looked like horses prepared for battle. On their heads they wore something like crowns of gold, and their faces resembled human faces.
8 Their hair was like women’s hair, and their teeth were like lions’ teeth.
9 They had breastplates like breastplates of iron, and 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 torment people for five months.
11 They had as king over them the angel of the Abyss, whose name in Hebrew is Abaddon, and in Greek, Apollyon.
