2 John 1:10-12

10 If anyone comes to you and does not bring this teaching, do not take him into your home or even greet him,

11 for the one who greets him shares in his evil deeds.

12 Although I have a great deal to write to you, I would prefer not to use paper and ink. Instead, I hope to come to you and talk with you face to face, so that our joy may be complete.
