¹ tn Grk “sons.”

² tc In light of the interpretive difficulty of this verse, a longer reading seems to have been added to clarify the meaning. The addition, in the middle of the sentence, makes the whole verse read as follows: “For he will execute his sentence completely and quickly in righteousness, because the Lord will do it quickly on the earth.” The shorter reading is found largely in Alexandrian mss (Ì⁴⁶ א* A B 6 1506 1739 1881 pc co), while the longer reading is found principally in Western and Byzantine mss (א² D F G Ψ 33 Ï lat). The longer reading follows Isa 10:22-23 (LXX) verbatim, while Paul in the previous verse quoted the LXX loosely. This suggests the addition was made by a copyist trying to make sense out of a difficult passage rather than by the author himself.

tn There is a wordplay in Greek (in both the LXX and here) on the phrase translated “completely and quickly” (συντελῶν καὶ συντέμνων, suntelwn kai suntemnwn). These participles are translated as adverbs for smoothness; a more literal (and more cumbersome) rendering would be: “The Lord will act by closing the account [or completing the sentence], and by cutting short the time.” The interpretation of this text is notoriously difficult. Cf. BDAG 975 s.v. συντέμνω.

sn A modified quotation from Isa 10:22-23. Since it is not exact, it has been printed as italics only.

³ tn Here καί (kai) has not been translated because of differences between Greek and English style.

⁴ tn Traditionally, “Lord of hosts”; Grk “Lord Sabaoth,” which means “Lord of the [heavenly] armies,” sometimes translated more generally as “Lord Almighty.”

⁵ sn A quotation from Isa 1:9.

⁶ tn Grk “Why? Because not by faith but as though by works.” The verb (“they pursued [it]”) is to be supplied from the preceding verse for the sake of English style; yet a certain literary power is seen in Paul’s laconic style.

⁷ tc Most mss, especially the later ones (א² D Ψ 33 Ï sy), read νόμου (nomou, “of the law”) here, echoing Paul’s usage in Rom 3:20, 28 and elsewhere. The qualifying phrase is lacking in א* A B F G 6 629 630 1739 1881 pc lat co. The longer reading thus is weaker externally and internally, being motivated apparently by a need to clarify.

tn Grk “but as by works.”

⁸ tn Grk “the stone of stumbling.”
