John Gill's Exposition of the Whole Bible
Revelation 11:5
And if any man will hurt them,.... Do any injury to their persons, or properties, oppose their writings, blaspheme their doctrines, and hinder their ministrations; whoever; they be, whether they be any that live among them, or in other parts; whether they be secret or open enemies; or whether they be of the outward court, or be really Gentiles or Papists; and especially if they do them any injustice, if they wrong, oppress, afflict, and distress them knowingly and willingly:
fire proceedeth out of their mouth; by which may be meant the word of God, which they preach and hold forth, which is comparable to fire, Jeremiah 23:29, both for light, it being a means of enlightening sinners, who are darkness itself; and of directing saints in their walk and conversation; and of detecting the errors, immoralities, idolatry, and superstition of men, and particularly of the church of Rome, who cannot bear the light of this word, and therefore forbid the reading of it to the laity, and keep it locked up from them in the Latin tongue: and also for the heat of it, it being the means of quickening, or of conveying a vital heat to dead sinners; and of warming and comforting the saints, causing their hearts to burn within them, while they bear or read it, or meditate upon it; and of scorching and tormenting reprobate sinners, and filling them with wrath, pain, and anguish, especially the followers of antichrist; and this is greatly designed, for this has a particular reference to the pouring out of the fourth vial, Revelation 16:9. Likewise, the word of God may be compared to fire for its purity in itself, for every word of his is pure; and for its purifying nature, when faithfully preached, and powerfully applied, it penetrates deep, it searches, and discovers, and purges from the dross of profaneness, false doctrine, and will worship; and for its consuming nature, as follows, it pronouncing damnation to unbelievers and impenitent sinners, and it being the savour of death unto death to such: or else the prayers of these witnesses are intended by the fire that proceeds out of their mouth, for vengeance on their enemies, who hinder their ministrations, blaspheme the truth, and shed their blood; which do not arise from a passionate and revengeful spirit, but from a pure zeal for the glory of God, and the honour of his name, and truth; and which prayers are heard by God, who will avenge his elect, that cry unto him day and night: the allusion is to the fire, which, at the request of Moses, came forth from the Lord, and destroyed two hundred and fifty persons, that opposed him and Aaron; and to the fire which Elias called for from heaven, upon the captains, and the fifties, that came to take him, who were types of these witnesses; see Numbers 16:3. And also this fire may denote the denunciations of God's wrath by them upon the antichristian party, these being as wood, and their words as fire, to consume them; see Jeremiah 5:14.
And devoureth their enemies: whether open or secret; just as the fire devoured Nadab and Abihu, the offerers of strange fire, which the Lord commanded not; so the fire out of the mouth of God's faithful servants devours such who introduce divers and strange doctrines, and the inventions of men, into the church of God; the light of God's word convinces and confounds them, though it may not convert them; it flashes in their consciences, and distresses them, so that they gnaw their tongues for pain; there being nothing but a fearful looking for of judgment, and fiery indignation, which shall devour and destroy them, though not corporeally, yet spiritually and eternally; for even these shall afterwards make war against them, conquer them, and slay them, and shall see them ascend to heaven,
And if any man will hurt them, he must in this manner be killed; this is repeated, partly to show the certainty of this destruction; and partly to point out the manner of it, which will be not by the use of carnal weapons: these enemies of the witnesses will not be killed by the sword, or any other weapon, but by the word of God, and through the prayers of the saints, and by the denunciations of God's judgments on them. The Jews express the doctrines and traditions of their Rabbins, delivered from one to another, by fire, proceeding out of their mouths; who say r,
"Rab sat before Rabbi, and "there went forth" דנור מפומיה
זיקוקין, "sparks of fire from the mouth of Rab", into the mouth of Rabbi, and from the mouth of Rabbi, into the mouth of Rab;''
which the gloss explains of their communicating their doctrines and traditions to one another.
