OET interlinear YAC (JAM) 2:7

uW Translation Notes:

Note 1 topic: figures-of-speech / rquestion

οὐκ αὐτοὶ βλασφημοῦσιν τὸ καλὸν ὄνομα τὸ ἐπικληθὲν ἐφ’ ὑμᾶς?

not they /are/_slandering the good name ¬which /having_been/_called on you_all

James is using the question form as a teaching tool. If it would be helpful in your language, you could express this question by translating his words as a statement or an exclamation. Alternate translation: “They are the ones who blaspheme the good name that has been called upon you!”

οὐκ αὐτοὶ βλασφημοῦσιν τὸ καλὸν ὄνομα

not they /are/_slandering the good name

The word blaspheme can have a technical sense. It can describe a human being wrongly denying that something is divine. But the word can also have the general sense of “insult,” and that is probably the sense in which James is using it here. (However, by insulting the name of Jesus, these rich people were also guilty of blasphemy in the technical sense, since Jesus is divine and his name should be honored.) Alternate translation: “Do they not insult the good name”

Note 2 topic: figures-of-speech / metonymy

τὸ καλὸν ὄνομα

the good name

James is referring to the name of Jesus by association with the way that it is good. Alternate translation: “the name of Jesus”

τὸ ἐπικληθὲν ἐφ’ ὑμᾶς
