Revelation 11:1-2

Then there was given to me a measuring rod like a staff; and someone said, “Rise and measure the temple of God and the altar [of incense], and [count] those who worship in it. [Ezek 40-42] But leave out the court [of the Gentiles] which is outside the temple and do not measure it, because it has been given to the Gentiles (the nations); and they will trample the holy city for forty-two months (three and one-half years). [Dan 8:9-14; Zech 12:3; Luke 21:24]
