3rd John 1:9

6 who bare witness to thy love before the church: whom thou wilt do well to set forward on their journey worthily of God:

7 because that for the sake of the Name they went forth, taking nothing of the Gentiles.

8 We therefore ought to welcome such, that we may be fellow-workers for the truth.

9 I wrote somewhat unto the church: but Diotrephes, who loveth to have the preeminence among them, receiveth us not.

10 Therefore, if I come, I will bring to remembrance his works which he doeth, prating against us with wicked words: and not content therewith, neither doth he himself receive the brethren, and them that would he forbiddeth and casteth [them] out of the church.

11 Beloved, imitate not that which is evil, but that which is good. He that doeth good is of God: he that doeth evil hath not seen God.

12 Demetrius hath the witness of all [men], and of the truth itself: yea, we also bear witness: and thou knowest that our witness is true.
