5 If anyone desires to harm them, fire proceeds out of their mouth and devours their enemies. If anyone desires to harm them, he must be killed in this way. 6 These have the power to shut up the sky, that it may not rain during the days of their prophecy. They have power over the waters, to turn them into blood, and to strike the earth with every plague, as often as they desire. 7 When they have finished their testimony, the beast that comes up out of the abyss will make war with them, and overcome them, and kill them. 8 Their dead bodies will be in the street of the great city, which spiritually is called Sodom and Egypt, where also their Lord was crucified. 9 From among the peoples, tribes, languages, and nations people will look at their dead bodies for three and a half days, and will not allow their dead bodies to be laid in a tomb. 10 Those who dwell on the earth rejoice over them, and they will be glad. They will give gifts to one another, because these two prophets tormented those who dwell on the earth.

Matthew Henry's Commentary on Revelation 11:5-10

Commentary on Revelation 11:3-13

(Read Revelation 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.
