Revelation 11:1-3

Then there was given me a measuring rod like a staff; and someone said, “Get up and measure the temple of God and the altar, and those who worship in it. Leave out the court which is outside the temple and do not measure it, for it has been given to the nations; and they will tread under foot the holy city for forty-two months. And I will grant authority to my two witnesses, and they will prophesy for twelve hundred and sixty days, clothed in sackcloth.”
