Revelation 6 is a chapter in the New Testament of the Bible that describes the opening of the first six seals of a scroll held by the Lamb, representing Jesus Christ. Each seal reveals a different event or vision that signifies the unfolding of the end times. The first four seals introduce the Four Horsemen of the Apocalypse, symbolizing conquest, war, famine, and death. The fifth seal reveals the souls of martyrs who cry out for justice, while the sixth seal depicts cosmic disturbances, such as earthquakes and darkened skies, indicating significant upheaval in the world.
