Revelation 11:3-5

Moffatt(i) 3 But I will allow my two witnesses to prophesy for twelve hundred and sixty days, clad in sackcloth 4 (they are the two olive-trees and the two lampstands which stand before the Lord of the earth): 5 whoever tries to harm them, fire will issue from their mouth and consume their enemies; whoever should try to harm them, so must he be killed."
