The Book of Daniel gives us the timeframe for the tribulation—seven years. However, Revelation provides considerable detail and specificity about what will occur during this period. Some chapters in the Book of Revelation are parenthetical, providing a broader timeframe for more detailed events. For example, Revelation chapter twelve provides an overview of Israel’s struggle with Satan for the past two thousand years, beginning with the birth of Christ and culminating in the time of Jacob’s trouble. Another example is in chapter thirteen, where we read about the rise of the Antichrist (the beast from the sea) and the false prophet (the beast from the earth). This chapter provides more detailed information about the kingdom of the Antichrist, revealed earlier in chapter six, which begins in the first year of the tribulation. Therefore, recognizing these parenthetical chapters is essential to interpreting the prophetic timeline.
