Revelation 11:3-6

3I will allow my two witnesses who wear sackcloth to speak what God has revealed. They will speak for 1,260 days.”

4These witnesses are the two olive trees and the two lamp stands standing in the presence of the Lord of the earth.

5If anyone wants to hurt them, fire comes out of the witnesses’ mouths and burns up their enemies. If anyone wants to hurt them, he must be killed the same way.

6These witnesses have authority to shut the sky in order to keep rain from falling during the time they speak what God has revealed. They have authority to turn water into blood and to strike the earth with any plague as often as they want.
