They had the 4th horseman of the apocalypse, aka the rider on the pale horse on display as well. They are letting you know what they are unleashing for you.
Revelation 6:8
8 And I looked, and behold a pale horse: and his name that sat on him was Death, and Hell followed with him. And power was given unto them over the fourth part of the earth, to kill with sword, and with hunger, and with death, and with the beasts of the earth.
These demons are using their human minions to taunt God and are about to get God to unleash His wrath upon them.
If you haven't already, accept Jesus as savior and live righteously because it won't be long before God's wrath comes upon the Earth.
