2 Thessalonians 2:3; 2 Thessalonians 2:7

2 Thessalonians 2:3

3 Let no one in any way deceive you, for it will not come unless the apostasy comes first, and the man of lawlessness is revealed, the son of destruction,

2 Thessalonians 2:7

7 For the mystery of lawlessness is already at work; only he who now restrains will do so until he is taken out of the way.
