“Thus he [an angel] said: ‘The fourth beast shall be a fourth kingdom on earth, which shall be different from all other kingdoms, and shall devour the whole earth, trample it and break it in pieces. The ten horns are ten kings who shall arise from this kingdom. And another shall rise after them; he shall be different from the first ones, and shall subdue three kings. He shall speak pompous words against the Most High, shall persecute the saints of the Most High, and shall intend to change times and law. Then the saints shall be given into his hand for a time and times and half a time [3½ years]. But the court shall be seated, and they shall take away his dominion, to consume and destroy it forever.’” Daniel 7:23-26.
“Now, brethren, concerning the coming of our Lord Jesus Christ and our gathering together to Him, we ask you, not to be soon shaken in mind or troubled, either by spirit or by word or by letter, as if from us, as though the day of Christ had come. Let no one deceive you by any means; for that Day will not come unless the falling away comes first, and the man of sin is revealed, the son of perdition, who opposes and exalts himself above all that is called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God.” 2 Thessalonians 2:1-4.
