if any one doth come unto you, and this teaching doth not bear, receive him not into the house, and say not to him, `Hail!'
if any one doth come unto you, and this teaching doth not bear, receive him not into the house, and say not to him, `Hail!'
2 John 1:8 See to yourselves that ye may not lose the things that we wrought, but a full reward may receive;
2 John 1:9 every one who is transgressing, and is not remaining in the teaching of the Christ, hath not God; he who is remaining in the teaching of the Christ, this one hath both the Father and the Son;
2 John 1:10 if any one doth come unto you, and this teaching doth not bear, receive him not into the house, and say not to him, `Hail!'
2 John 1:11 for he who is saying to him, `Hail,' hath fellowship with his evil works.
2 John 1:12 Many things having to write to you, I did not intend through paper and ink, but I hope to come unto you, and speak mouth to mouth, that our joy may be full;
The verse centers on "doth", "come", "teaching", "bear", "receive", "house", and "hail". It is saying that the verse draws attention to "doth" and "come", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 9's "every one who is transgressing and is..." into verse 11's "for he who is saying to him...", so "doth" and "come" belong inside that flow. In 2 John context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "doth" and "come" with trust shaped by these words, not by a vague optimism outside the passage.
