Antichrist and His Armies Will Surround Jerusalem
These passages refer to Jerusalem being trodden down by the Gentiles. Since Revelation 11:2 occurs during the second half of the 70th week of years, Luke 21:20 must also. Therefore, Jerusalem must be surrounded by armies at the midpoint of the 70th week of years.
And when ye shall see Jerusalem compassed with armies, then know that the desolation thereof is nigh. (Luke 21:20)
But the court which is without the temple leave out, and measure it not; for it is given unto the Gentiles: and the holy city shall they tread under foot forty [and] two months. (Revelation 11:2)
