Revelation 11:3-6

ASV(i) 3 And I will give unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth. 4 These are the two olive trees and the two candlesticks, standing before the Lord of the earth. 5 And if any man desireth to hurt them, fire proceedeth out of their mouth and devoureth their enemies; and if any man shall desire to hurt them, in this manner must he be killed. 6 These have the power to shut the heaven, that it rain not during the days of their prophecy: and they have power over the waters to turn them into blood, and to smite the earth with every plague, as often as they shall desire.
