The grace of our Lord Jesus Christ be with all of you.
Verse 18. The grace of our Lord Jesus Christ be with you all. . From the subscription to this epistle, it purports to have been "written from Athens." This is probably incorrect, as there is reason to think that it was written from Corinth. See the Introduction. At all events, this subscription is of no authority. See Notes at the end of the Epistles to the Romans and 1 Corinthians.
He closes every Epistle by praying for GRACE to those whom he addresses. Amen--omitted in the oldest manuscripts It was doubtless the response of the congregation after hearing the Epistle read publicly; hence it crept into copies. The Subscription is spurious, as the Epistle was written not "from Athens," but from Corinth. Next: 1 Timothy Introduction
The grace of our Lord Jesus Christ be with you all. Amen. This was the sign or token; See Gill on Rom 16:20 The subscription to this epistle is, "The Second Epistle to the Thessalonians was written from Athens"; though it seems rather to be written from Corinth.
