Revelation 11:3-7

11:3 And I will grant my two witnesses authority to prophesy for 1,260 days, dressed in sackcloth. 11:4 (These are the two olive trees and the two lampstands that stand before the Lord of the earth.) 11:5 If anyone wants to harm them, fire comes out of their mouths and completely consumes their enemies. If anyone wants to harm them, they must be killed this way. 11:6 These two have the power to close up the sky so that it does not rain during the time they are prophesying. They have power to turn the waters to blood and to strike the earth with every kind of plague whenever they want. 11:7 When they have completed their testimony, the beast that comes up from the abyss will make war on them and conquer them and kill them.
