If you want to get a deeper understanding of Revelation 6, then read Isaiah 19, these two passages describe the same period of the Awakening of the Church. In Isaiah's prophecy, we find three types of believers: "Egyptians", "Assyrians" and "Israel". The type of believer "Egyptians" is a deeply religious type of person. They can kneel before Jesus Christ, because in their imagination He is like the despot Pharaoh. The Egyptians are very superstitious, they pay attention to all sorts of signs, they are afraid of the barcode, they tell each other horror stories about the implantation of microchips in the right hand. It is this category of believers that will be frightened by the "light cloud" of people who support the idea of the Third Temple as a meeting place for the elect from the four winds. The rider on the white horse of the Third Temple will scare them, they will see in him a sign of the Apocalypse. Another category of believers is the "Assyrians". These are worldly believers who will flood into Christian congregations after the awakening of the "Egyptians." This stream of new people from the world will be "Mager-shalal-hash-baz". Such people will easily accept the authority of the Antichrist, because he will promise them material gains in exchange for their prayers. The third category of believers is Israel, the heirs of God. These are the elect from the four winds who will appear in the Third Temple when it is built. This is "Immanuel", which Isaiah opposes to the robber Mager-shalal-hash-baz.
