| Geneva Study Bible {16} The salutation of Paul with mine own hand, which is the token in every epistle: so I write. (16) The apostle writes the conclusion of his letter with his own hand, so that false letters might not be brought and put in place of true ones. People's New Testament 3:17 With mine own hand. Here he adds the salutation in his own handwriting. The Epistle thus far had been written by one to whom he dictated, as was his custom, but he now adds his autograph. Which is the token of every epistle. This autograph was proof of the genuineness. Their attention is perhaps called to this on account of a spurious epistle (2Th 2:2). Jamieson-Fausset-Brown Bible Commentary 17. The Epistle was written by an amanuensis (perhaps Silas or Timothy), and only the closing salutation written by Paul's "own hand" (compare Ro 16:22; 1Co 16:21; Col 4:18). Wherever Paul does not subjoin this autograph salutation, we may presume he wrote the whole Epistle himself (Ga 6:11). which-which autograph salutation. the token-to distinguish genuine Epistles from spurious ones put forth in my name (2Th 2:2). in every epistle-Some think he signed his name to every Epistle with his own hand; but as there is no trace of this in any manuscripts of all the Epistles, it is more likely that he alludes to his writing with his own hand in closing every Epistle, even in those Epistles (Romans, Second Corinthians, Ephesians, Philippians, First Thessalonians) wherein he does not specify his having done so. so I write-so I sign my name: this is a specimen of my handwriting, by which to distinguish my geniune letters from forgeries. Matthew Henry's Concise Commentary 3:16-18 The apostle prays for the Thessalonians. And let us desire the same blessings for ourselves and our friends. Peace with God. This peace is desired for them always, or in every thing. Peace by all means; in every way; that, as they enjoyed the means of grace, they might use all methods to secure peace. We need nothing more to make us safe and happy, nor can we desire any thing better for ourselves and our friends, than to have God's gracious presence with us and them. No matter where we are, if God be with us; nor who is absent, if God be present. It is through the grace of our Lord Jesus Christ, that we hope to have peace with God, and to enjoy the presence of God. This grace is all in all to make us happy; though we wish ever so much to others, there remains enough for ourselves. |
