[1:2] 1 tn Grk “brothers,” but the Greek word may be used for “brothers and sisters” or “fellow Christians” as here (cf. BDAG 18 s.v. ἀδελφός 1, where considerable nonbiblical evidence for the plural ἀδελφοί [adelfoi] meaning “brothers and sisters” is cited). Where the plural term is used in direct address, as here, “brothers and sisters” is used; where the term is singular and not direct address (as in v. 9), “believer” is preferred.
