Revelation 11:3-6

And I will give power unto my two witnesses Here God promises to raise up some true and faithful witnesses to preach and protest against the innovations and inventions which he foresaw would corrupt Christianity, especially in the western parts of Europe. “Of these witnesses,” says Bishop Newton, “there should be, though but a small, yet a competent number; and it was a sufficient reason for making them two witnesses, because that is the number required by the law, and approved by the gospel, Deuteronomy 19:15; Matthew 18:16; and upon former occasions two have often been joined in commission, as Moses and Aaron in Egypt, Elijah and Elisha in the apostacy of the ten tribes, and Zerubbabel and Joshua after the Babylonish captivity, to whom these witnesses are particularly compared. Our Saviour himself sent forth his disciples, (Luke 10:1,) two and two; and it hath been observed also that the principal reformers have usually appeared, as it were, in pairs; as the Waldenses and Albigenses, John Huss and Jerome of Prague, Luther and Calvin, Cranmer and Ridley, and their followers. Not that I conceive that any two particular men, or two particular churches, were intended by this prophecy; but only that there should be some in every age, though but a few in number, who should bear witness to the truth, and declare against the iniquity and idolatry of their times. They should not be discouraged even by persecution and oppression, but, though clothed in sackcloth, and living in a mourning and afflicted state, should yet prophesy Should yet preach the sincere word of God, and denounce the divine judgments against the reigning idolatry and wickedness: and this they should continue to do, as long as the grand corruption itself should last, for the space of twelve hundred and sixty days, which is the same space of time with the forty and two months, before mentioned, the period assigned for the tyranny and idolatry of the Church of Rome. The witnesses, therefore, cannot be any two men, or any two churches, but must be a succession of men, and a succession of churches.”

A character is then given of these witnesses, and of the power and effect of their preaching. These are the two olive-trees, and the two candlesticks, &c., Revelation 11:4 That is, they, like Zerubbabel and Joshua, (Zechariah 4.,) are the great instructers and enlighteners of the church. Fire proceedeth out of their mouth, and devoureth their enemies, Revelation 11:5 That is, they are like unto Moses and Elijah, (Numbers 16.; 2 Kings 1.,) who called for fire upon their adversaries. But their fire was real, this is symbolical, and proceedeth out of the mouth of the witnesses, denouncing the divine vengeance on the corrupters and opposers of true religion; much in the same manner as it was said to Jeremiah, (Jeremiah 5:14,) I will make my words in thy mouth fire, and this people wood, and it shall devour them. These have power to shut heaven, that it rain not, &c., Revelation 11:6 That is, they are like Elijah, who foretold a want of rain in the days of Ahab, (1 Kings 17:1; James 5:17,) and it rained not on the earth for the space of three years and six months, which, mystically understood, is the same space of time as the forty and two months, and the twelve hundred and sixty days, which are allotted for the prophesying of the witnesses. During this time the divine protection and blessing shall be withheld from those men who neglect and despise their preaching and doctrine. They have also power over the waters, &c. That is, they are like Moses and Aaron, who inflicted these plagues on Egypt; and they may be said to smite the earth with the plagues which they denounce; for, in Scripture language, the prophets are often said to do those things which they declare and foretel. But it is most highly probable that these particulars will receive a more literal accomplishment when the plagues of God, and the vials of his wrath (chap. 16.) shall be fully poured out upon men, in consequence of their having so long resisted the testimony of the witnesses. Their cause and the cause of truth will finally be avenged on all their enemies.
