47 For John says, “And I will give power unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth.” That is the half of the week whereof Daniel spoke. “These are the two olive trees and the two candlesticks standing before the Lord of the earth. And if any man will hurt them, fire will proceed out of their mouth, and devour their enemies; and if any man will hurt them, he must in this manner be killed. These have power to shut heaven, that it rain not in the days of their prophecy; and have power over waters, to turn them to blood, and to smite the earth with all plagues as often as they will.
And when</em> they shall have finished their course and their testimony,” what says the prophet? “the beast that ascends out of the bottomless pit shall make war against them, and shall overcome them, and kill them,” because they will not give glory to Antichrist. For this is meant by the little horn that grows up. He, being now elated in heart, begins to exalt himself, and to glorify himself as God, persecuting the saints and blaspheming Christ, even as Daniel says, “I considered the horn, and, behold, in the horn were eyes like the eyes of man, and a mouth speaking great things; and he opened his mouth to blaspheme God. And that born made war against the saints, and prevailed against them until the beast was slain, and perished, and his body was given to be burned.”
