2 Thessalonians 2:3-4

21st Century King James Version

³ Let no man deceive you by any means, for that Day shall not come, unless there come a falling away first, and that man of sin be revealed, the son of perdition,

⁴ who opposeth and exalteth himself above all that is called God or that is worshiped, so that he sitteth as God in the temple of God, showing himself to be God.
