2 John 1:3

1:3 Grace, mercy, and ¹  peace will be with us from God the Father and from ²  Jesus Christ the Son of the Father, in truth and love.

2 John 1:10

1:10 If anyone comes to you and does not bring this teaching, do not receive him into your house and do not give him any greeting, ³ 

[1:3]  ¹ tn “And” is not in the Greek text. It is supplied for smoothness in English.

[1:3]  ² tc Most witnesses, including some early and important ones (א P 33 Ï sy), have κυρίου (kuriou, “Lord”) before ᾿Ιησοῦ Χριστοῦ (Ihsou Cristou, “Jesus Christ”), but this is a typical scribal addition, motivated by pietistic and liturgical concerns. Further, early and excellent mss (A B Ψ 048 0232 81 323 1739 al) lack κυρίου. Thus, both internally and externally, the shorter reading is strongly preferred.

[1:10]  ³ sn Do not give him any greeting does not mean to insult the person. It means “do not greet the person as a fellow Christian” (which is impossible anyway since the opponents are not genuine believers in the author’s opinion).
