2 Thessalonians 2:3-4

Amplified Bible, Classic Edition

³ Let no one deceive or beguile you in any way, for that day will not come except the ^[a]apostasy comes first [unless the predicted great ^[b]falling away of those who have professed to be Christians has come], and the man of lawlessness (sin) is revealed, who is the son of doom (of perdition),^(A)

⁴ Who opposes and exalts himself so proudly and insolently against and over all that is called God or that is worshiped, [even to his actually] taking his seat in the temple of God, proclaiming that he himself is God.^(B)
