Revelation 11:5-7

New Catholic Bible

⁵ If anyone tries to harm them, fire pours forth from their mouths and consumes their enemies. Anyone who attempts to harm them will surely be killed in this manner. ⁶ They have the power to shut up the sky so that it does not rain during the time they are prophesying. They also have the power to turn water into blood and to afflict the earth with every type of plague as often as they desire.

⁷ When they have completed their testimony, the beast that comes up from the abyss will wage war against them and overpower and kill them.
