OET interlinear ROM 2:23

uW Translation Notes:

Note 1 topic: figures-of-speech / rquestion

ὃς ἐν νόμῳ καυχᾶσαι διὰ τῆς παραβάσεως τοῦ νόμου, τὸν Θεὸν ἀτιμάζεις

who in law /are/_boasting through the transgression ˱of˲_the law ¬the God ˱you˲_/are/_dishonoring

As in the previous two verses, Paul is not asking for information here, but is using the question form to emphasize the truth of what he is saying. If you would not use a rhetorical question for this purpose in your language, you could translate his words as a statement or exclamation and communicate the emphasis in another way. Alternate translation: [You who boast in the law actually dishonor God through the transgression of the law!]

Note 2 topic: figures-of-speech / metaphor

ὃς ἐν νόμῳ καυχᾶσαι

who in law /are/_boasting

Paul uses in the law as if it were something that people could boast inside of. He means that the Jews brag that they are the only nation who knows God’s law, which has similar meaning to “boast in God” in 2:17. If it would be helpful in your language, you could express the meaning plainly. Alternative translation, “You, who brag that you are the only ones who know God’s law”

Note 3 topic: figures-of-speech / abstractnouns

διὰ τῆς παραβάσεως τοῦ νόμου

through the transgression ˱of˲_the law

If your language does not use an abstract noun for the idea of transgression, you could express the same idea in another way. Alternate translation: [by transgressing the law] or [by breaking the law]
