“Demetrius hath good report of all men, and of the truth itself: yea, and we also bear record; and ye know that our record is true.”
King James Version (KJV)
1:12 And from the truth itself - That is, what they testify is the very truth. Yea, we also bear testimony - I and they that are with me.
3Jo 1:12 Demetrius hath good report by all [men]. Of this Demetrius we know nothing more. Perhaps he was a member of the same church as Diotrephes, whose example is contrasted.
