Revelation 11:1-6

Then I was given a reed like a measuring rod. And the angel stood, saying, “Rise and measure the temple of God, the altar, and those who worship there. But leave out the court which is outside the temple, and do not measure it, for it has been given to the Gentiles. And they will tread the holy city underfoot for forty-two months. And I will give power to my two witnesses, and they will prophesy one thousand two hundred and sixty days, clothed in sackcloth.” These are the two olive trees and the two lampstands standing before the God of the earth. And if anyone wants to harm them, fire proceeds from their mouth and devours their enemies. And if anyone wants to harm them, he must be killed in this manner. These have power to shut heaven, so that no rain falls in the days of their prophecy; and they have power over waters to turn them to blood, and to strike the earth with all plagues, as often as they desire.
