Revelation 11:3-6

3I will give authority to my two servants who speak my message clearly. They will tell people my messages for 1,260 days. They will wear rough clothes made from goats' hair.’

4These servants are the two olive trees and the two lampstands. They stand in front of God who is the Lord of the earth.

5If anyone tries to hurt them, fire comes out of the servants' mouths. This fire destroys their enemies. Anyone who wants to hurt the two servants must die in this way.

6These servants of God have authority to shut up the sky. Then there will be no rain during the time that they tell their messages from God. They also have authority to cause the water on earth to become blood. They can cause many different kinds of trouble to happen on the earth. They can do this as often as they want to.
