1 Korintus 1:31

1:31 so that, as it is written, “Let the one who boasts, boast in the Lord.” ¹ 

1 Korintus 9:8

9:8 Am I saying these things only on the basis of common sense, ²  or does the law not say this as well?

1 Korintus 10:2

10:2 and all were baptized ³  into Moses in the cloud and in the sea,

[1:31]  ¹ sn A quotation from Jer 9:24. The themes of Jer 9 have influenced Paul’s presentation in vv. 26-31. Jeremiah calls upon the wise, the strong, and the wealthy not to trust in their resources but in their knowledge of the true God – and so to boast in the Lord. Paul addresses the same three areas of human pride.

[9:8]  ² tn Or “only according to human authority”; Grk “saying these things according to men.”

[10:2]  ³ tc ‡ A number of witnesses, some of them important, have the passive ἐβαπτίσθησαν (ebaptisqhsan, “were baptized”) instead of the middle ἐβαπτίσαντο (ebaptisanto, “baptized [themselves]”) in v. 2 (so א A C D F G Ψ 33 al latt). However, the middle is not without its representation (Ì^46c B 1739 1881 Ï Or; the original hand of Ì⁴⁶ read the imperfect middle ἐβαπτίζοντο [ebaptizonto]). The passive looks like a motivated reading in that it is clearer and conforms to typical Pauline usage (his thirteen instances of the verb are all either active or passive). B. M. Metzger, in representing a minority opinion of the UBS Committee, suggests that the middle would have been appropriate for Jewish baptism in which the convert baptizes himself (TCGNT 493). But this assumes that the middle is a direct middle, a rare occurrence in the NT (and never elsewhere with this verb). Further, it is not really baptism that is in view in v. 2, but passing through the Red Sea (thus, a metaphorical use). Although the present editors agree with the minority’s resultant reading, it is better to take the middle as causative/permissive and the scribes as changing it to a passive for clarity’s sake. Translational differences are minimal, though some exegetical implications are involved (see ExSyn 427).
