4 The Lord also spoke as follows to those who did not believe in Him: “I have come in my Father's name, and you have not received Me: when another shall come in his own name, him you will receive,” calling Antichrist “the other,” because he is alienated from the Lord. This is also the unjust judge, whom the Lord mentioned as one “who feared not God, neither regarded man,” to whom the widow fled in her forgetfulness of God—that is, the earthly Jerusalem,— to be avenged of her adversary.
Which also he shall do in the time of his kingdom: he shall remove his kingdom into that [city], and shall sit in the temple of God, leading astray those who worship him, as if he were Christ. To this purpose Daniel says again: “And he shall desolate the holy place; and sin has been given for a sacrifice, and righteousness been cast away in the earth, and he has been active (fecit), and gone on prosperously.” And the angel Gabriel, when explaining his vision, states with regard to this person: “And towards the end of their kingdom a king of a most fierce countenance shall arise, one understanding [dark] questions, and exceedingly powerful, full of wonders; and he shall corrupt, direct, influence (faciet), and put strong men down, the holy people likewise; and his yoke shall be directed as a wreath [round their neck]; deceit shall be in his hand, and he shall be lifted up in his heart: he shall also ruin many by deceit, and lead many to perdition, bruising them in his hand like eggs.” And then he points out the time that his tyranny shall last, during which the saints shall be put to flight, they who offer a pure sacrifice unto God: “And in the midst of the week,” he says, “the sacrifice and the libation shall be taken away, and the abomination of desolation [shall be brought] into the temple: even unto the consummation of the time shall the desolation be complete.” Now three years and six months constitute the half-week.
