OET interlinear 1YHN (1JHN) 3:15

uW Translation Notes:

Note 1 topic: figures-of-speech / metaphor

πᾶς ὁ μισῶν τὸν ἀδελφὸν αὐτοῦ, ἀνθρωποκτόνος ἐστίν

everyone ¬which hating the brother ˱of˲_him /a/_murderer is

John is using the term murderer, and he is echoing the teaching of Jesus that is recorded in Matthew 5:21–22. John means that since people commit murder because they hate other people, anyone who hates is the same on the inside as someone who actually kills another person. It may be helpful to translate this metaphor as a simile. Alternate translation: [Whoever hates another believer is just like someone who kills a person]

Note 2 topic: figures-of-speech / metaphor

τὸν ἀδελφὸν αὐτοῦ

the brother ˱of˲_him

See how you translated his brother in 2:9. Alternate translation: [a fellow believer]

Note 3 topic: figures-of-speech / doublenegatives

πᾶς ἀνθρωποκτόνος οὐκ ἔχει ζωὴν αἰώνιον

everyone any murderer not /is/_having life eternal

If it would be helpful in your language, you could make the subject negative and the verb positive. Alternate translation: [no murderer has eternal life]

Note 4 topic: figures-of-speech / metaphor

ζωὴν αἰώνιον

life eternal

Since John is speaking of a present reality, by eternal life he does not mean living forever in the presence of God after death, which is one thing that this expression can describe. Rather, he means the regenerating power that God gives to believers in this life that helps them to stop sinning and to do what pleases him. Clearly, anyone who is a murderer does not have this power at work in him. Alternate translation: [the power that God gives to help us become new people]

Note 5 topic: figures-of-speech / personification

οὐκ ἔχει ζωὴν αἰώνιον ἐν αὐτῷ μένουσαν

not /is/_having life eternal in (Some words not found in SR-GNT: πᾶς ὁ μισῶν τὸν ἀδελφὸν αὐτοῦ ἀνθρωποκτόνος ἐστίν καὶ οἴδατε ὅτι πᾶς ἀνθρωποκτόνος οὐκ ἔχει ζωὴν αἰώνιον ἐν ἑαυτῷ μένουσαν)

See the discussion of the term “remain” in Part 3 of the Introduction to 1 John. In this instance, John seems to be using the term literally, in the sense of “residing,” to depict eternal life as if it were a living thing that could actively reside within a person. Alternate translation: [has not received eternal life]
