3 John 1:11

9 I have written to the church about this, but Diotrephes, who loves to be first, will not accept our instruction.

10 So if I come, I will call attention to his malicious slander against us. And unsatisfied with that, he refuses to welcome the brothers and forbids those who want to do so, even putting them out of the church.

Beloved, do not imitate what is evil, but what is good. The one who does good is of God; the one who does evil has not seen God.

12 Demetrius has received a good testimony from everyone, and from the truth itself. We also testify for him, and you know that our testimony is true.

13 I have many things to write to you, but I would prefer not to do so with pen and ink.

Do read the surrounding verses too, because the context often says more than a single verse.
