1 tc Grk “the brother.” Later witnesses (א2 D2 Ï) have ἀνδρί (andri, “husband”) here, apparently in conscious emulation of the earlier mention of ἀνήρ (ajnhr) in the verse. However, the earliest and best witnesses (Ì46 א* A B C D* F G P Ψ 33 1739 al co) are decisively in favor of ἀδελφῷ (adelfw, “brother”), a word that because of the close association with “wife” here may have seemed inappropriate to many scribes. It is also for reasons of English style that “her husband” is used in the translation.
2 tn Grk “brothers.” See note on the phrase “brothers and sisters” in 1:10.
