17 And in my vision I saw the horses and their riders: they had breastplates red as fire, blue as sapphire, and yellow as sulfur. The horses' heads were like lions' heads, and from their mouths came out fire, smoke, and sulfur.
18 A third of the human race was killed by those three plagues: the fire, the smoke, and the sulfur coming out of the horses' mouths.
19 For the power of the horses is in their mouths and also in their tails. Their tails are like snakes with heads, and they use them to hurt people.
20 The rest of the human race, all those who had not been killed by these plagues, did not turn away from what they themselves had made. They did not stop worshiping demons, nor the idols of gold, silver, bronze, stone, and wood, which cannot see, hear, or walk.
21 Nor did they repent of their murders, their magic, their sexual immorality, or their stealing.
