Revelation 9:13-21 - A Third Of Humanity Killed By Plagues
13 When the sixth angel blew his trumpet, I heard a voice from the four horns of the gold altar in front of God. 14 It told the sixth angel who had the trumpet, "Release the four angels who are held at the great Euphrates River." 15 So the four angels who were ready for that hour, day, month, and year were released to kill one-third of humanity. 16 The number of cavalry troops was 200,000,000. I heard how many there were. 17 This was how I saw the horses in my vision: The riders wore breastplates that had the color of fire, sapphire, and sulfur. The heads of the horses were like lions' heads, and fire, smoke, and sulfur came out of their mouths. 18 By these three plagues the fire, the smoke, and the sulfur that came out of their mouths one-third of humanity was killed. 19 For the power of these horses is in their mouths and their tails. Their tails have heads like snakes, which they use to inflict pain.
20 The rest of the people who survived these plagues did not repent from their evil actions or stop worshiping demons and idols made of gold, silver, bronze, stone, and wood, which cannot see, hear, or walk. 21 They did not repent from their murders, their witchcraft, their sexual immorality, or their thefts.
