Rev 11:4-7

Revelation 11:4-7  4 These are the two olive trees and the two lampstands that stand before the Lord of the earth.  5 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 way.  6 These men have power to shut heaven, so that no rain falls during the days of their prophecy; and they have authority over the waters to turn them into blood, and to strike the earth with every plague, as often as they wish.  7 And when they finish their testimony, the Beast who ascends out of the bottomless pit will make war with them, and will overcome them, and will kill them.
