OET interlinear 2COR 6:18

uW Translation Notes:

Note 1 topic: writing-quotations

καὶ

and

Here Paul uses the word And to introduce another quote from the Old Testament, specifically from 2 Samuel 7:8 and 2 Samuel 7:14. If it would be helpful in your language, you could use a word or phrase that clarifies that Paul is quoting from the Old Testament. Alternate translation: [Again, as you can read in the Scriptures,] or [Even more, as it is written,]

Note 2 topic: figures-of-speech / parallelism

ἔσομαι ὑμῖν εἰς πατέρα, καὶ ὑμεῖς ἔσεσθέ μοι εἰς υἱοὺς καὶ θυγατέρας

˱I˲_will_be ˱to˲_you_all for /a/_father and you_all will_be ˱to˲_me for sons and daughters

These two clauses mean basically the same thing. The second emphasizes the meaning of the first by repeating the same idea with different words. Hebrew poetry was based on this kind of repetition, and it would be good to show this to your readers by including both phrases in your translation rather than combining them. However, if the repetition might be confusing, you could connect the phrases with a word other than and in order to show that the second phrase is repeating the first one, not saying something additional. Alternate translation: [I will be to you as a Father; yes, you will be to me as sons and daughters]
