The fourth horseman in Revelation is riding a “pale” horse. Not being sure what color “pale” is, I looked up the word. The Greek word from which pale is translated is chlōros (χλωρός).
Here are the other places where the word chloros is used.
I am not sure why they deviated from translating the word to green here, but I think that we should use the contextual definition of the word, since there is greater evidence that it is referring to a definite vegetative green. I also looked up where the word green is used elsewhere in the Bible. These verses are the only place where the greek word is used, but the Hebrew word for green is used in the old testament. There are several words in the hebrew that are translated “green”. They are not usually referring to color. Some of them are adjectives for young plants using the term green like we do. We might say a cowboy who is just learning to ride is “green”. But every time except for one, a verse about the temple hangings describing the colors, the word translated green is referring to vegetation of some kind. So I think it is safe to assume that our pale horse’s color symbolizes vegetation.
He is given a fourth part of the earth. Earth is also translated lands. It is not necessarily a death sentence on a fourth part of humans, but on a fourth part of the countries. That would be like the entire continent of Africa. He kills with sword, famine and with beasts. Beasts can refer to large or small animals, from wolves to snakes and bees and wasps. This is in agreement with the four horsemen in Ezekiel that each one goes in a different direction through out the earth as if they are given jurisdiction. That explains why the pale horseman is given power over a fourth of the earth. I would surmise that each horseman as his own quarter. But there may be significance that it is specified here and not with the other horsemen. Everything means something. Perhaps the three horses will go throughout the whole earth and the fourth will only have power over a fourth of the lands.
Another supposition I have is that the first three horsemen brought domination, famine and war, but death from those things do not begin until later. The pale horseman brings death using the judgments of the first three with exception of the wild beasts.
Therion, the greek word for beast, is the title Alister Crowley gave himself, is the name of a genus of wasps, and is a god in Thelema, consort of Babalon
