1 Corinthians 6:8

6:8 But you yourselves wrong and cheat, and you do this to your brothers and sisters! ¹ 

1 Corinthians 14:39

14:39 So then, brothers and sisters, ²  be eager to prophesy, and do not forbid anyone from speaking in tongues. ³ 

1 Corinthians 15:31

15:31 Every day I am in danger of death! This is as sure as ⁴  my boasting in you, ⁵  which I have in Christ Jesus our Lord.

[6:8]  ¹ tn Grk “brothers.” The Greek term “brother” literally refers to family relationships, but here it is used in a broader sense to connote familial relationships within the family of God (cf. BDAG 18 s.v. ἀδελφός 2.a). See also the note on the phrase “brothers and sisters” in 1:10.

[14:39]  ² tc ‡ μου (mou, “my”) is found after ἀδελφοί (adelfoi) in a number of significant witnesses (א A B* D¹ 048 326 1175 2464 al), but lacking in most other witnesses (Ì⁴⁶ B² D* F G Ψ 0243 33 1739 1881 Ï lat). Every other time Paul says “So then, brothers (and sisters)” he adds “my” (ὥστε, ἀδελφοί μου; {wste, adelfoi mou). There is no good reason why scribes would intentionally omit “my” here but not elsewhere. Thus, the longer reading is in conformity with Paul’s general style and as such seems to be scribally motivated. NA²⁷ has the word in brackets, indicating doubt as to its authenticity.

[14:39]  ³ tn Grk “speaking in tongues.” The words “anyone from” are supplied for the sake of clarity.

[15:31]  ³ tn Or, more literally, “I swear by the boasting in you.”

[15:31]  ⁴ tc ‡ Although the witnesses for the shorter reading (Ì⁴⁶ D F G Ψ 075 0243 1739 1881 Ï) are not as strong as for the addition of ἀδελφοί (adelfoi, “brothers”) at this juncture (א A B K P 33 81 104 365 1175 2464 lat sy co), it is difficult to find a reason why scribes would either intentionally or unintentionally drop the address here. Thus, the shorter reading is slightly preferred.
