[4:17] 1 tc ‡ Several important mss read ᾿Ιησοῦ (Ihsou, “Jesus”) after Χριστῷ (Cristw, “Christ”) in v. 17 (so Ì46 א C D1 33 1739 al). Western mss have κυρίῳ ᾿Ιησοῦ (kuriw Ihsou, “Lord Jesus”; D* F G), while several significant mss, as well as the majority, have only Χριστῷ here (A B D2 Ψ Ï sa). Once ᾿Ιησοῦ got into the text, it would continue to be copied. There is however no easy explanation for the word lacking in so many witnesses. Thus the shorter reading appears to be original. NA27 includes ᾿Ιησοῦ in brackets, indicating doubt as to its authenticity.
[11:2] 2 tc The Western and Byzantine texts, as well as one or two Alexandrian mss (D F G Ψ 33 Ï latt sy), combine in reading ἀδελφοί (adelfoi, “brothers”) here, while the Alexandrian witnesses (Ì46 א A B C P 81 630 1175 1739 1881 2464 co) largely lack the address. The addition of ἀδελφοί is apparently a motivated reading, however, for scribes would have naturally wanted to add it to ἐπαινῶ δὲ ὑμᾶς (epainw de Juma", “now I praise you”), especially as this begins a new section. On the other hand, it is difficult to explain how the shorter reading could have arisen from the longer one. Thus, on both internal and external grounds, the shorter reading is strongly preferred.
