Matthew Poole and continuators on Revelation 11:5

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.

That is, my faithful Ministers, the two Olive-branches before-mentioned, which fill the Candlesticks with Oyl.

Here is a plain Allusion to the Stories of Moses and Elias, calling for Fire from Heaven; but God sheweth, that the Victory of his Ministers under the Gospel shall not be by a miraculous Fire called for down from Heaven (as Elias, hurt the Captains and their Bands sent to apprehend him) but by Fire out of their Mouths, according to that, Jer. 5.14. Behold, I will make my words in thy mouth fire, and this People wood, and it shall devour them; See also Ier. 1.9, 10. This also is according to Zechariah's Vision before-mentioned, and the Revelation of the Will of God in it, v. 6. Not by Might, nor by Power, but by my Spirit, saith the Lord of Hosts. The meaning is, That they shall be too hard for them, either by their faithful, lively, and powerful preaching, or by their fervent Prayers.
