Revelation 11:5-6

Riverside(i) 5 If any one wishes to harm them fire comes from their mouths and consumes their enemies. If any one shall wish to harm them, in this way he must be killed. 6 They have power to shut up heaven so that no rain shall fall during the days that they are prophesying, and they have power over the waters to turn them into blood and power to smite the earth with every kind of plague as often as they please.
