2. The Argument of the Epistle.
Thus Saint Paul, writing again to the Thessalonians, comforts them, and fortifies them against afflictions: and renders them more certain concerning the advent of the Lord and the signs preceding and portending it, namely, the apostasy and revelation of the man of sin, and confirms believers against the fear of seduction: and, finally, prohibits all ἀταξίαν/disorderliness and impiety in life.
 2 Thessalonians 3:6, 7, 11: “Now we command you, brethren, in the name of our Lord Jesus Christ, that ye withdraw yourselves from every brother that walketh disorderly (ἀτάκτως), and not after the tradition which he received of us. For yourselves know how ye ought to follow us: for we behaved not ourselves disorderly (ἠτακτήσαμεν) among you…. For we hear that there are some which walk among you disorderly (ἀτάκτως), working not at all, but are busybodies.”
