We have confidence in the Lord concerning you, that you both do and will do the things we command.
The things which we command ...  It is considered deplorable that, following Hendriksen, many commentators have postulated plural authorship of 2Thessalonians; Kelcy, for example, speaks repeatedly of "the writers" of this epistle.  There was only one writer, the apostle Paul.  The "we" in this place is editorial, or epistolary.  Timothy and Silvanus had no right whatever to "command" the Thessalonians to do anything, except in the secondary sense of telling them the facts of the gospel.  Paul, on the other hand, was endowed with plenary authority as an apostle commissioned to reveal the content of Christ's message authoritatively.  Silvanus and Timothy did not authenticate this epistle at the end of the chapter; Paul did so!
