3 John 8-10
New International Version
8 We ought therefore to show hospitality to such people so that we may work together for the truth.
9 I wrote to the church, but Diotrephes, who loves to be first, will not welcome us. 10 So when I come,(A) I will call attention to what he is doing, spreading malicious nonsense about us. Not satisfied with that, he even refuses to welcome other believers.(B) He also stops those who want to do so and puts them out of the church.(C)
