SEV Biblia, Chapter 1:12
¶ Todos dan testimonio de Demetrio, y aun la misma verdad; y tambin nosotros damos testimonio; y vosotros habis conocido que nuestro testimonio es verdadero.
Clarke's Bible Commentary - 3 John 1:12
Verse 12. Demetrius hath good report] Perhaps another member of the Church where Caius was; or he might have been one of those whom the apostle recommends to Caius; or, possibly, the bearer of this letter from John to Caius. He seems to have been an excellent person: all testified of his righteousness; the truth - Christianity, itself bore testimony to him; and the apostles themselves added theirs also.
John Gill's Bible Commentary
Ver. 12. Demetrius hath good report of all [men] , This man was of a quite different cast from Diotrephes, and therefore the apostle makes mention of him to Gaius, to be followed by him, and not the other; he was either the same with Demas, which is a contraction of this name, or the person that John sent from Ephesus with this letter: we read of an Ephesian of this name, ( Acts 19:24); though not the same person; or else one that also was a member of the same church with Gaius and Diotrephes; and he being kind and beneficent, obtained a good report of the generality of men, not only of the brethren, but of those that were without; for a liberal man is universally respected. The Syriac version adds, and of the church itself; as distinct from all men, or the generality of the men of the world: and of the truth itself ; that is, whoever speaks truth must give him a good character, for this cannot be understood with any propriety of the Gospel, nor of Jesus Christ: yea, and we also bear record ; or a testimony to the character of Demetrius; that is, I, John, the apostle, and the saints at Ephesus: and ye know that our record is true ; faithful, and to be depended upon. The Alexandrian copy, and several others, read, thou knowest, as does also the Vulgate Latin version, which seems most agreeable, since this epistle is directed to a single person; compare this with ( John 19:35); and it will give a further proof of this epistle being the Apostle John's.
Matthew Henry Commentary
Verses 9-12 - Both the heart and mouth must be watched. The temper and spirit of Diotrephes was full of pride and ambition. It is bad not to do goo ourselves; but it is worse to hinder those who would do good. Thos cautions and counsels are most likely to be accepted, which ar seasoned with love. Follow that which is good, for he that doeth good as delighting therein, is born of God. Evil-workers vainly pretend of boast acquaintance with God. Let us not follow that which is proud selfish, and of bad design, though the example may be given by person of rank and power; but let us be followers of God, and walk in love after the example of our Lord.
