The "ride of the four horsemen" has been a subject for discussion for a long time. And it should be noted by any "Christian" that this "ride" has a set point in time when it began, with which Revelation 6:1-4 gives the year when their "ride" started, and verses 5-8 provides further details.
At Revelation 6:1, 2 is seen a rider on "a white horse", who is crowned king of God's Kingdom (Dan 7:13, 14), who then goes forth "conquering and to complete his conquest", showing that God's Kingdom was then "set up".(Dan 2:44a and Ps 110:1, 2)
Who is this "rider" ? Jesus Christ, who is seen again at Revelation 19:11 as riding on "a white horse" and at Psalms 45:4 as the one who ' rides in the cause of truth and humility and righteousness '. But what follows in rapid succession helps sincere individuals to establish the date when the "ride of the four horsemen" commenced."(Note: the color white symbolizes spiritual and moral cleanness, see Rev 7:9 and 19:8)
At Ezekiel 21:25-27, it establishes that Zedekiah was the last king to set on "Jehovah's throne" in 618 B.C.E.(1 Chron 29:23) before he was removed in 607 B.C.E. with the destruction of Jerusalem by Babylonian king Nebuchadnezzar, saying: "This is what the Sovereign Lord Jehovah says: ' Remove the turban, and take off the crown. This will not remain the same. Raise up the low one (or Jesus as seen at Isaiah 53:2, 3), and bring low the high one (king Zedekiah). A ruin, a ruin, a ruin, I will make it. And it ("Jehovah's throne") will not belong to anyone until the one who has the legal right comes (or receives the crown as the rightful king of God's Kingdom), and I (Jehovah God) must give it to him".(see also Gen 49:10 that shows that "the scepter will not depart from Judah, neither the commander's staff from between his feet, until Shiloh (meaning "He Whose It Is; He to Whom It Belongs") comes, and to him the obedience of the peoples belong")
Now, at Revelation 6:3, 4, the second "rider" comes forth, on a "fiery colored horse", that "was granted (or permitted by God) to the one seated on it to take peace away from the earth so that they should slaughter one another, and he was given a great sword".(Note: the color red can depict violence, such as the "dragon" being "fiery-colored" and wages war with the "woman" at Rev 12:3, 4; see also Rev 19:12, whereby Jesus "eyes are a fiery flame", as well as Num 21:8 in which Moses was told by Jehovah to build a "fiery snake" out of copper and place it on a pole for those who had been bitten by poisonous snakes and then looked at it in order to save themselves from death)
When was "peace take away from the earth so that they should slaughter one another" on a global scale ? With the outbreak of World War I on July 28, 1914, that cost an estimated 21 million lives over some four years of war, called "the Great War" until the outbreak of World War II on September 1, 1939.(Note: some feel that World War II broke out on Sept 19, 1931 when Japan invaded Manchuria, but most historians agree with Germany's invasion of Poland as the starting point of WWII)
What resulted or followed with the outbreak of global warfare ? The "rider" on a "black horse" (with the color black depicting serious trouble, ominous, such as "black clouds approaching") bringing forth famine or starvation, in which the "rider" had "a pair of scales" to carefully measure food, and whereby prices went "through the roof ", of "a quart of wheat for a denarius (or a whole day's wage in the first century) and three quarts of barley for a denarius; and do not harm the olive oil and the wine (reserved only for the very rich who could afford them)".(Rev 6:5, 6; Note: the United Kingdom had to have repeated convoys of ships loaded with food from the United States during WWII in order to stave off starvation for the British people, and of which German U-boats sank many of the ships)
The next "rider" to come forth was on a "pale horse" (the color pale signifies sickness that is at times followed by death, such as "you look pale and don't look good", think COVID-19) "and the one seated on it had the name Death. And the Grave (Greek Hades, the King James Bible reads "hell") was closely following him. And authority was given them (or with permission from Jehovah God, see Jesus words to Pilate John 19:11) over the fourth part (or a large swath) of the earth, to kill with a long sword (rider on the "fiery-colored horse") and with food shortage (rider on the "black horse") and with deadly plague (rider on the "pale horse" that brings on the pandemic such as COVID-19) and by the wild beasts of the earth (or political governments, see Dan 7:1-8)".(Rev 6:7, 8)
So, what has been learned ? That Jesus was crowned king of God's Kingdom in 1914, that set off a chain reaction of events, because he also fought against "the dragon" or Satan the Devil and his demon angels and threw them out of heaven, being "hurled down to the earth", so that "woe for the earth (the more stable elements who support Satan's political system or "the wild beast", Rev 13:1-3) and for the sea (the restless masses of mankind, who are never satisfied with the political status quo, see Isa 57:20, 21), because the Devil has come down to you, having great anger, knowing that he has a short period of time" before his being thrown into "the abyss" or state of inactivity.(Rev 12:7-9, 12; 20:1-3)
Note: there is also another way to establish the year when the "ride of the four horsemen" was set in motion, that of Daniel 4 concerning "a tree in the midst of the earth, and its height was enormous" (Dan 4:10), whereby it lays out a time line, using Babylonian king Nebuchadnezzar as an example, of God [whose personal name is Jehovah, Isa 26:4] removing whom he wishes in order "that people living may know that the Most High is Ruler in the kingdom of mankind and that he gives it whomever he wants, and he set over it even the lowliest of men" (Dan 4:17), pointing to his crowning Jesus Christ, as at Psalms 2 that states: "The One enthroned in the heavens will laugh; Jehovah will scoff at them (the political nations who do want Jehovah's rulership over them, Ps 2:1-3). At that time he will speak to them in his anger, saying: "I myself have installed my king on Zion (or heavenly Jerusalem, see Heb 12:22), my holy mountain".(Ps 2:5, 6)
This "tree" whose "top reached to the heavens" represented Jehovah's rulership through David's lineage (see 2 Sam 7, whereby Jehovah established an everlasting covenant with David, for his "offspring" through whom God will "firmly establish the throne of his kingdom forever"), and of which it was ' chopped down ' in 607 B.C.E.
It was held from "growing" or in "stasis" with a symbolic "banding of iron and copper" for a period of 7 times or 2520 days literally, but logic shows that the days are really years, in view of Numbers 14:34 and Ezekiel 4:6, so that a period of 2,520 years would pass from 607 B.C.E. until "the one who has the legal right" to Jehovah's throne was crowned king of God's Kingdom in 1914.
Thus, the "ride of the four horsemen" began in 1914 and will end at the battle of Armageddon, the war between God's Kingdom and the political nations and their supporters.(Rev 16:14, 16; 19:19-21)
