This refers to the seventieth, and only unfulfilled, week of Daniel’s prophecy. It is divided into two halves, the division being marked by Antichrist throwing off the mask of deceit, and beginning the fearful persecution of the saints for three and a half years, marked by the slaying of the two witnesses at the commencement (Rev. 14). At the close of this period Christ will publicly return to the Mount of Olives, and destroy the Man of Sin with the brightness of His coming (2 Thess. 2).
