The caution against interpreting images also applies to numbers, which are often used in a symbolic manner.
Whether it be the “time, times, and half a time” of Daniel 7 or the “seventy weeks” of Daniel 9 or the one thousand years of Revelation 20, the original readers would probably have recognized some of these as symbols, and not literal figures. This is the nature of apocalyptic literature.
Take, for instance, the seventy weeks (or seventy sevens) of Daniel 9. Is this 490 literal years? If so, where does this fit in history? Antiochus Epiphanes? The first or second coming of Jesus Christ? The Roman Empire? Take your pick, or choose from a dozen or so interpretations.
These interpretations of the seventy weeks all have one thing in common: they can distract us from the primary message of Daniel’s visions: God has determined the time when He will put an end to sin and suffering.
