3 John 1:9-10 (New International Version)

 ⁹I wrote to the church, but Diotrephes, who loves to be first, will have nothing to do with us. ¹⁰So if I come, I will call attention to what he is doing, gossiping maliciously about us. Not satisfied with that, he refuses to welcome the brothers. He also stops those who want to do so and puts them out of the church.
