3 John 1:6-10

who bare witness to thy love before the church: whom thou wilt do well to set forward on their journey worthily of God: because that for the sake of the Name they went forth, taking nothing of the Gentiles. We therefore ought to welcome such, that we may be fellow-workers for the truth. I wrote somewhat unto the church: but Diotrephes, who loveth to have the preeminence among them, receiveth us not. 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.
