2 John 1:10-12

10 If there come any unto you, and bring not this doctrine, receive him not into [your] house, neither bid him God-The Father speed:

11 For he that biddes him God-The Father speed is partaker of his evil deeds.

12 Having many things to write unto you, I would not [write] with paper and ink: but I trust to come unto you, and speak face to face, that our joy may be full.
