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.

² tc Χριστόν (Criston, “Christ”) is attested in the majority of mss, including many important witnesses of the Alexandrian (Ì⁴⁶ 1739 1881) and Western (D F G) texttypes, and other mss and versions (Ψ latt sy co). On the other hand, some of the important Alexandrian witnesses have κύριον (kurion, “Lord”; א B C P 33 104 1175 al). A few mss (A 81 pc) have θεόν (qeon, “God”). The nomina sacra for these readings are quite similar (cMn, kMn, and qMn respectively), so one might be able to account for the different readings by way of confusion. On closer examination, the variants appear to be intentional changes. Alexandrian scribes replaced the highly specific term “Christ” with the less specific terms “Lord” and “God” because in the context it seems to be anachronistic to speak of the exodus generation putting Christ to the test. If the original had been “Lord,” it seems unlikely that a scribe would have willingly created a difficulty by substituting the more specific “Christ.” Moreover, even if not motivated by a tendency to overcorrect, a scribe might be likely to assimilate the word “Christ” to “Lord” in conformity with Deut 6:16 or other passages. The evidence from the early church regarding the reading of this verse is rather compelling in favor of “Christ.” Marcion, a second-century, anti-Jewish heretic, would naturally have opposed any reference to Christ in historical involvement with Israel, because he thought of the Creator God of the OT as inherently evil. In spite of this strong prejudice, though, {Marcion} read a text with “Christ.” Other early church writers attest to the presence of the word “Christ,” including {Clement of Alexandria} and Origen. What is more, the synod of Antioch in a.d. 268 used the reading “Christ” as evidence of the preexistence of Christ when it condemned Paul of Samosata. (See G. Zuntz, The Text of the Epistles, 126-27; TCGNT 494; C. D. Osburn, “The Text of 1 Corinthians 10:9,” New Testament Textual Criticism: Its Significance for Exegesis, 201-11; contra A. Robertson and A. Plummer, First Corinthians [ICC], 205-6.) Since “Christ” is the more difficult reading on all accounts, it is almost certainly original. In addition, “Christ” is consistent with Paul’s style in this passage (cf. 10:4, a text in which {Marcion} also reads “Christ”). This text is also christologically significant, since the reading “Christ” makes an explicit claim to the preexistence of Christ. (The textual critic faces a similar dilemma in Jude 5. In a similar exodus context, some of the more important Alexandrian mss [A B 33 81 pc] and the Vulgate read “Jesus” in place of “Lord.” Two of those mss [A 81] are the same mss that have “Christ” instead of “God” in 1 Cor 10:9. See the tc notes on Jude 5 for more information.) In sum, “Christ” has all the earmarks of authenticity here and should be considered the original reading.

³ sn This incident is recorded in Num 21:5-9.

⁴ tn Grk “by the destroyer.” BDAG 703 s.v. ὀλοθρευτῆς mentions the corresponding OT references and notes, “the one meant is the destroying angel as the one who carries out the divine sentence of punishment, or perh. Satan.”

sn This incident is recorded in Num 16:41-50.

⁵ tn Grk “spiritual things.”

⁶ tn Grk “brothers.” See note on the phrase “brothers and sisters” in 1:10.

⁷ tn Grk “ignorant.”

⁸ sn The questions in vv. 29-30 all expect a negative response.

⁹ sn The Greek term builds (himself) up does not necessarily bear positive connotations in this context.

¹⁰ tc Although the majority of mss (א A C D Ψ 075 Ï lat bo) conclude this letter with ἀμήν (amhn, “amen”), such a conclusion is routinely added by scribes to NT books because a few of these books originally had such an ending (cf. Rom 16:27; Gal 6:18; Jude 25). A majority of Greek witnesses have the concluding ἀμήν in every NT book except Acts, James, and 3 John (and even in these books, ἀμήν is found in some witnesses). It is thus a predictable variant. Although far fewer witnesses lack the valedictory particle (B F 0121 0243 33 81 630 1739* 1881 sa), their collective testimony is difficult to explain if the omission is not authentic.
