Matthew 24 says, “And there will be famines and earthquakes in various places”. And Revelation says, “And he was given authority over a fourth of the earth, to kill with sword, with famine, with pestilence, and by wild beasts of the earth.” Matthew adds earthquakes to the equation. We will start with earthquakes. The number of earthquakes has been reasonably consistent over the decades. With around 1500 a year over 4 on the Richter scale. In the sixties, that amount doubled to 3000. The seventies saw 6,000, the eighties saw 12000, the nineties saw 24000, the two thousands saw 48000, and the last decade has seen over 100,000. This fits the pattern that each of these riders went out forty years apart. The same patterns can be seen in disastrous weather patterns that cause famine in many places. The pictures of starving people bursting onto our TV screens in untold megapixels mainly come from Africa, but this has been a worldwide pattern. They call it climate change, and it is man-made. It is man-made, alright, by man's wicked behaviour and the impending judgement.
The pale rider is Death, followed by Hades. Death and Hades are the names of the most important angels and beasts in Sheol. Sheol appears to be divided into three regions. The closest to us is Hades, who also gives his name to the place. The next level is Death, and the lowest is the bottomless pit, where Abaddon reigns and his name is sometimes given to it. The bottomless pit is for Fallen Angels. Later on, in Revelations, it says that Hades, Death, and the sea give up their dead for the final judgement of men. Abaddon is not mentioned. Angels and all those other spiritual creatures have judgements they will have to face.

Luke 17:26–27 Just as it was in the days of Noah, so will it be in the days of the Son of Man. They were eating and drinking and marrying and being given in marriage until the day when Noah entered the ark, and the flood came and destroyed them all. Life will appear to be normal for those who have not awakened. No giants, Nephilim, or spaceships. You may find that demonic spirits are emboldened, but that will be all. But that is a story for another time.
The Pale Green rider and the colour sorrel, a yellow/green, are interesting, and their relationship is with a quarter of the world's population. Muslims are the only defined group that makes up a quarter of the world's population. The African countries being hit time and again with droughts are Muslim countries or parts of countries that are Muslim. The national colour of Islam is green. Green is on many flags of Islamic countries. Muammar Gadaffi once described the struggle between Muslim countries and the West as the battle between the white and the green. In 1964, the Arab League was set up, which quickly led to the 1967 Israeli war. A disaster for them. There has been increasing violence ever since. With a great increase over the last decade with the Obama Wars. (Arab Spring).
If it is not a particular group of people but people in general, then pestilence is the most likely cause of death for those many people. That they are to kill 25% of all people. Germ warfare became popular with the Germans in World War II. Without much success. In 1964, they started work on the Corona virus, primarily as a vaccine but also as a weapon. By 1965, they had concluded that the Corona virus was ideal for the task. In 1974, they started testing modifying the virus using other animals. The first vaccines were patented in 1990. By 1998, it was announced that these types of vaccines did not work. In 2002, the virus was included in the first mRNA vaccine patent. The patent was called “an infectious, replication-defective clone. That is a name straight out of a horror movie. Within one year, we had the first SARS outbreak. In 2005, the vaccine was classified as a “biotech technology and a bio-weapon enabling agent. Using official records through Dr. Faucci's office. Only 5 million was spent at Wuhan of the billions spent on these experiments. It makes you think they were being set up as patsies. If the pestilence is the vaccine for COVID-19. In the first year, deaths from all causes were up 35% on average across the world. The second year shows that all-cause death is up three times that. If it triples each year, then by 2027, around 25% of the world's population will be dead. Sadly, as time goes on, the COVID-19 vaccine doomsdayers are proving to be right.

Although he is very active, the last thing he, Death, has to do is kill 25% of the world's population. A job for Death and Hades. That's about 1.9 billion, given that he has already killed about a couple hundred million, which leaves 1.6 to 1.7 billion. That is an event that is going to change everything.
