3 John 1:12

12 Demetrius has witness borne to him by all, and by the truth itself; and *we* also bear witness, and thou knowest [a] that our witness is true.

3 John 1:12 In-Context

10 For this reason, if I come, I will bring to remembrance his works which he does, babbling against us with wicked words; and not content with these, neither does he himself receive the brethren; and those who would he prevents, and casts [them] out of the assembly.
11 Beloved, do not imitate what is evil, but what is good. He that does good is of God. He that does evil has not seen God.
12 Demetrius has witness borne to him by all, and by the truth itself; and *we* also bear witness, and thou knowest that our witness is true.
13 I had many things to write to thee, but I will not with ink and pen write to thee;
14 but I hope soon to see thee, and we will speak mouth to mouth. Peace [be] to thee. The friends greet thee. Greet the friends by name.
