The antichrist does not speak out of the Bible. The Bible, both Old Testament and New Testament prophesy about him relative to what the Bible refers to as the latter days as per messianic eschatology/prophecy.
There are a number of terms pertaining to the end time antichrist, such as "little horn" in Daniel 7, "beast" (two horned) in Revelation 13, "man of sin" II Thessalonians 2:3, "antichrist" I John 2 18-23 and "false prophet" Revelation 19:20, 20:10.
Note in the Daniel texts as well as the Revelation account the antichrist prevails against the saints of God and "wears them out," i.e tribulation/persecution of Christians.
The Revelation text has the antichrist/false prophet cast into the lake of fire where Satan the devil also ends up as per Revelation 20:10. So ends the phenomena of evil in the universe.
The antichrist works in conjunction with and by the power of Satan. Thus he will hate Israel and Christianity. He will work to destroy Israel as per Revelation 12,13 and to fight the Christians/saints as per Revelation 13. His MO of killing will be beheading as per Revelation 20. He will have political power worldwide as per Revelation and Daniel. The nations which he uses to fight Israel in the latter days are listed in Ezekiel 38 as well as other OT prophets.
He will stand in the "holy place" which is the Temple Mount where now stands the Dome of the Rock, Islamic holy place. Matthew 24:15
Here he is refered to by Jesus as
the abomination of desolation. This one is also refenced in the Old Testament Daniel 9:27 text as the "one who makes desolate."
Go figure! As the old saying goes,
if it looks like a duck, quacks like a duck and flaps it's wings like a duck, it likely is a duck.
