Revelation 9:9-11

New Catholic Bible

⁹ and their chests were like iron breastplates. The sound of their wings was like the rumble of many horses and chariots rushing into battle.

¹⁰ These locusts had tails and stings like those of scorpions, and in their tails they had the power to torment people for five months. ¹¹ They had as their king the angel of the abyss, whose name in Hebrew is Abaddon, and in Greek, Apollyon.
