Chapters 8 through 11 in the Book of Revelation describe John's vision of the seventh seal. Chapter 8 describes the opening of this seal and the plagues of the first four trumpet angels of the seventh seal. Chapters 9 through 11 describe the plagues of the fifth trumpet angel (First Woe) and the sixth trumpet angel (Second Woe). The Second Woe coincides in time with the seven-year Battle of Armageddon, including the ministry of the Two Witnesses in Jerusalem during the last 3-1/2 years of this battle as described in Revelation 11. Watch here for the verse-by-verse podcasts for chapters 8 through 11 as they are published in a future day.
