Daniel 8 speaks of 2,300 days in a prophecy concerning a persecution of the Jewish people during the intertestamental period. Similarly, in Revelation 11 and 12, John mentions 1,260 days in two prophecies concerning another persecution of the Jews during the end times. The main differences between these two prophecies are 1) Daniel’s has been fulfilled, and John’s has not; and 2) Daniel predicts the actions of Antiochus Epiphanes, and John predicts those of the Antichrist.
The prophecy of the 2,300 days (“evenings and mornings”) is found in Daniel 8:13–14:
“Then I heard a holy one speaking, and another holy one said to him, ‘How long will it take for the vision to be fulfilled—the vision concerning the daily sacrifice, the rebellion that causes desolation, the surrender of the sanctuary and the trampling underfoot of the Lord’s people?’ He said to me, ‘It will take 2,300 evenings and mornings; then the sanctuary will be reconsecrated.’”
The time period covered, 2,300 days, figures to about 6 1/3 years. We believe this prophecy was fulfilled before the birth of Christ, during the reign of the Seleucid king Antiochus IV (Epiphanes). Antiochus desecrated the temple in Jerusalem and severely persecuted the Jews from about September 171/170 BC to December 165/164 BC. When Antiochus died, the Jews purified and rededicated the temple, just as Daniel had predicted. These events are commemorated in the celebration of Hanukkah.
The detailed prophecies contained in God’s Word are part of what makes the Bible unique among religious texts. Our God can “make known the end from the beginning, from ancient times, what is still to come” (Isaiah 46:10), and He has revealed significant events in the future, counting out the very days of those periods of time.
