Revelation 11:3-5

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.
