3. Let no one deceive or beguile you in any way, for that day will not come except the apostasy comes first [unless the predicted great 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), [Dan. 7:25; 8:25; I Tim. 4:1.]
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. [Ezek. 28:2; Dan. 11:36, 37.]
5. Do you not recollect that when I was still with you, I told you these things?
