This passage describes the events of the fifth trumpet judgment from Revelation chapter 9. An angel falls from heaven and is given the key to the bottomless pit. When opened, smoke arises and darkens the sun. Locusts emerge from the smoke and are given power to torment people for five months. The locusts have the appearance of horses prepared for battle and have faces of men, hair of women, teeth of lions, armor, and scorpion-like tails. They are led by the angel of the bottomless pit named Abaddon or Apollyon, meaning "Destroyer." Despite the torment, people do not repent of their sins.
