Revelation 11:3

1 Then I was given a measuring rod like a staff and was told, “Go and measure the temple of God and the altar, and count the number of worshipers there.

2 But exclude the courtyard outside the temple. Do not measure it, because it has been given over to the nations, and they will trample the holy city for 42 months.

3 And I will empower my two witnesses, and they will prophesy for 1,260 days, clothed in sackcloth.”

4 These witnesses are the two olive trees and the two lampstands that stand before the Lord of the earth.

5 If anyone wants to harm them, fire proceeds from their mouths and devours their enemies. In this way, anyone who wants to harm them must be killed.

6 These witnesses have power to shut the sky so that no rain will fall during the days of their prophecy, and power to turn the waters into blood and to strike the earth with every kind of plague as often as they wish.

7 When the two witnesses have finished their testimony, the beast that comes up from the Abyss will wage war with them, and will overpower and kill them.
