Revelation 11:1-3
The Fate of the Two Witnesses
11:1 Then a measuring rod like a staff was given to me, and I was told, “Get up and measure the temple of God, and the altar, and the ones who worship there.
11:2 But do not measure the outer courtyard of the temple; leave it out, because it has been given to the Gentiles, and they will trample on the holy city for forty-two months.
11:3 And I will grant my two witnesses authority to prophesy for 1,260 days, dressed in sackcloth.
