3 John 1:6; 3 John 1:9-10

6 and they have testified to your love before the church. You will do well to send them on their way in a manner worthy of God.
9 I wrote something to the church; but Diotrephes, who loves to be first among them, does not accept what we say. 10 For this reason, if I come, I will call attention to his deeds which he does, unjustly accusing us with wicked words; and not satisfied with this, he himself does not receive the brethren, either, and he forbids those who desire to do so and puts them out of the church.
