Revelation 11:4-6

These are the two olive trees and the two lampstands that stand before the Lord of the earth. And if anyone wants to harm them, fire comes out of their mouth and consumes their enemies. And if anyone wants to harm them, in this way he must be killed. These have the authority to shut the sky, so that it does not rain during the days of their prophecy. And they have authority over the waters, to turn them to blood, and to strike the earth with every plague as often as they wish.
