{9} 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.

(9) The power and surety of the holy ministry, which is truly evangelical, is declared both in earth and in heaven, protecting the administers of it, and destroying its enemies, in this verse, divine power, most mightily showing itself forth in heaven, earth and the sea in Re 11:6 as it is described in 2Co 10:4 according to the promise of Christ in Mr 16:17. This is the second place (as I said before) of the combats which the servants of God must undergo in the executing of their calling, and of the things that follow the same combats or conflicts are these things to overcome, in these two verses: to be overcome and killed in Re 11:7 After the slaughter follow these things, that the carcasses of the godly, laid abroad in Re 11:8 and being unburied, are scorned, together with cursing and bitter abhorrance Re 11:9 and that therefore congratulations are publicly and privately made in Re 11:10.

People's New Testament

11:6 These have power, etc. In seeking for the two witnesses we must find agencies which can save life and can destroy it, can shut the heavens and open them, can prevent blessings from descending upon the earth, can inflict curses and plagues on the inhabitants of the earth. The witnesses have supernatural powers.

Wesley's Notes

11:6 These have power - And they use that power. See verse 10. Rev 11:10 To shut heaven, that it rain not in the days of their prophesying - During those twelve hundred and sixty days. And have power over the waters - In and near Jerusalem. To turn them into blood - As Moses did those in Egypt. And to smite the earth with all plagues, as often as they will - This is not said of Moses or Elijah, or any mere man besides. And how is it possible to understand this otherwise than of two individual persons?

Jamieson-Fausset-Brown Bible Commentary

6. These . power-Greek, "authorized power."

it rain not-Greek, "huetos brechee," "rain shower not," literally, "moisten" not (the earth).

smite . with all plagues-Greek, "with (literally, 'in') every plague."

Matthew Henry's Concise Commentary

11:3-13 In the time of treading down, God kept his faithful witnesses to attest the truth of his word and worship, and the excellence of his ways, The number of these witnesses is small, yet enough. They prophesy in sackcloth. It shows their afflicted, persecuted state, and deep sorrow for the abominations against which they protested. They are supported during their great and hard work, till it is done. When they had prophesied in sackcloth the greatest part of 1260 years, antichrist, the great instrument of the devil, would war against them, with force and violence for a time. Determined rebels against the light rejoice, as on some happy event, when they can silence, drive to a distance, or destroy the faithful servants of Christ, whose doctrine and conduct torment them. It does not appear that the term is yet expired, and the witnesses are not a present exposed to endure such terrible outward sufferings as in former times; but such things may again happen, and there is abundant cause to prophesy in sackcloth, on account of the state of religion. The depressed state of real Christianity may relate only to the western church. The Spirit of life from God, quickens dead souls, and shall quicken the dead bodies of his people, and his dying interest in the world. The revival of God's work and witnesses, will strike terror into the souls of his enemies. Where there is guilt, there is fear; and a persecuting spirit, though cruel, is a cowardly spirit. It will be no small part of the punishment of persecutors, both in this world, and at the great day, that they see the faithful servants of God honoured and advanced. The Lord's witnesses must not be weary of suffering and service, nor hastily grasp at the reward; but must stay till their Master calls them. The consequence of their being thus exalted was a mighty shock and convulsion in the antichristian empire. Events alone can show the meaning of this. But whenever God's work and witnesses revive, the devil's work and witnesses fall before him. And that the slaying of the witnesses is future, appears to be probable.
