2 John 1:10 ASV

⁸  Look to yourselves, that ye lose not the things which we have wrought, but that ye receive a full reward.

⁹  Whosoever goeth onward and abideth not in the teaching of Christ, hath not God: he that abideth in the teaching, the same hath both the Father and the Son.

¹⁰  If any one cometh unto you, and bringeth not this teaching, receive him not into `your' house, and give him no greeting:

¹¹  for he that giveth him greeting partaketh in his evil works.

¹²  Having many things to write unto you, I would not `write them' with paper and ink: but I hope to come unto you, and to speak face to face, that your joy may be made full.
