Revelation 11:3-5

King James Version

³ And I will give power unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth.

⁴ These are the two olive trees, and the two candlesticks standing before the God of the earth.

⁵ And if any man will hurt them, fire proceedeth out of their mouth, and devoureth their enemies: and if any man will hurt them, he must in this manner be killed.
