Properly, “greenish-yellow,” like young grass or unripe wheat. Homer applies it to honey, and Sophocles to the sand. Generally, “pale, pallid.” Used of a mist, of sea-water, of a pale or bilious complexion. Thucydides uses it of the appearance of persons stricken with the plague (ii., 49). In Homer, it is used of the paleness of the face from fear, and so as directly descriptive of fear (“Iliad,” x., 376; xv., 4). Of olive wood (“Odyssey,” ix., 320, 379) of which the bark is gray.2
The word to describe the fourth horse’s color, chlōros (“pale green”), is the color of grass and other vegetation in Mark 6:39 and Rev. 8:7+; 9:4+, but in the present connection, designates the yellowish green of decay, the pallor of death. It is a pale ashen color that images a face bleached because of terror. It recalls a corpse in the advanced state of corruption (Ford).3Death, and Hades followed
If today’s  world population figure of five billion is used, . . . “one fourth of the earth” means that Death and Hades have authority, which they apparently will exercise, to take the lives of one and a quarter billion people. The magnitude of this catastrophe can hardly be grasped because nothing comparable has happened throughout history (Swete). If limited to two continents, which it will probably not be (Beckwith; Lenski; Mounce), it will amount to the elimination of people from two of the world’s most populous ones (Walvoord).4Since Thomas wrote, the world population has risen to over 6 billion [December 2003] which would result in the death of over 1.5 billion people.5 This number would be reduced by the believers in Christ who are taken in the Rapture prior to this period.sword. . . hunger. . . death. . . beasts
Throughout human history, disease has killed people on a far more massive scale than war. More Union and Confederate soldiers died from disease during the Civil War than were killed in battle. An estimated 30 million people died during the great influenza epidemic of 1918-19 —more than three times as many as the estimated 8.5 million soldiers who died in battle during World War I.8Those who survive the first three will be so weak as to be unable to defend themselves from wild beasts which will become emboldened and attack them.
So it shall be a reproach and a taunt, an instruction and an astonishment, unto the nations that are round about thee, when I shall execute judgments on thee in anger and in wrath, and in wrathful rebukes; (I, Jehovah, have spoken it;) when I shall send upon them the evil arrows of famine, that are for destruction, which I will send to destroy you: and I will increase the famine upon you, and will break your staff of bread; and I will send upon you famine and evil beasts, and they shall bereave thee; and pestilence and blood shall pass through thee; and I will bring the sword upon thee: I, Jehovah, have spoken it. (Eze. 5:15-17) [emphasis added]
Thus says the Lord GOD: “Pound your fists and stamp your feet, and say, ’Alas, for all the evil abominations of the house of Israel! For they shall fall by the sword, by famine, and by pestilence. He who is far off shall die by the pestilence, he who is near shall fall by the sword, and he who remains and is besieged shall die by the famine.” Thus will I spend My fury upon them. (Eze. 6:11-12) [emphasis added]From these passages we understand that what seem like intensified natural disturbances (war, hunger, death, attack by beasts) are in fact expressions of God’s judgment. Thus God’s wrath is already seen in the fourth seal—well in advance of the sixth and seventh seals.9 The picture being drawn is one of no escape. No matter which group or location a man finds himself in, there is a God-ordained judgment which will result in death:
For thus saith the Lord Jehovah: “How much more when I send my four sore judgments upon Jerusalem, the sword, and the famine, and the evil beasts, and the pestilence, to cut off from it man and beast!” (Eze. 14:21) [emphasis added]
Thus shalt thou say unto them, “Thus saith the Lord Jehovah: ‘As I live, surely they that are in the waste places shall fall by the sword; and him that is in the open field will I give to the beasts to be devoured; and they that are in the strongholds and in the caves shall die of the pestilence.’ ” (Eze. 33:27) [emphasis added]Amos predicted this character of the day of Jehovah: “Woe unto you that desire the day of Jehovah! Wherefore would ye have the day of Jehovah? It is darkness, and not light. As if a man did flee from a lion, and a bear met him; or went into the house and leaned his hand on the wall, and a serpent bit him. Shall not the day of Jehovah be darkness, and not light? even very dark, and no brightness in it?” (Amos 5:18-20).There is intentional irony in God’s reversal of roles as men become the source of food for beasts (Gen. 9:2-3 cf. Eze. 29:5; 39:17-20; Rev. 19:17-18+). When man is disobedient to God, He reverses the original divine order where man was given dominion over the beasts (Gen. 1:26-28; 9:2-3) and gives man into the hand of beasts (Lev. 26:22; Deu. 32:24). The beasts will be emboldened both because of the emaciated and sickly condition of men and the scarceness of their own food supply. “Once food becomes scarce, wild animals which generally leave man alone will begin to attack man for food.”10
