2 Thessalonians 3:17 - Clarke's commentary and critical notes on the Bible

The salutation of Paul with mine own hand, which is the token in every epistle: so I write. The salutation of Paul with mine own hand - It is very likely that Paul employed an amanuensis generally, either to write what he dictated, or to make a fair copy of what he wrote. In either case the apostle always subscribed it, and wrote the salutation and benediction with his own hand; and this was what authenticated all his epistles. A measure of this kind would be very necessary if forged epistles were carried about in those times. See the note on 1 Corinthians 16:21, and see Colossians 4:18 (note).
