2Th 2:3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;
2Th 2:4 Who opposeth and exalteth himself above all that is called GOD, or that is worshiped; so that he as GOD sitteth in the temple of GOD, showing himself that he is GOD.

2Th 2:14 Whereunto he called you by our gospel, to the obtaining of the glory of our Lord Jesus Christ.
2Th 2:15 Therefore, brethren, stand fast, and hold the traditions which ye have been taught, whether by word, or our epistle.
