Roma 2:19-24

2:19 and if you are convinced ¹  that you yourself are a guide to the blind, a light to those who are in darkness, 2:20 an educator of the senseless, a teacher of little children, because you have in the law the essential features of knowledge and of the truth – 2:21 therefore ²  you who teach someone else, do you not teach yourself? You who preach against stealing, do you steal? 2:22 You who tell others not to commit adultery, do you commit adultery? You who abhor ³  idols, do you rob temples? 2:23 You who boast in the law dishonor God by transgressing the law! 2:24 For just as it is written, “the name of God is being blasphemed among the Gentiles because of you.” ⁴ 

Roma 14:21

14:21 It is good not to eat meat or drink wine or to do anything that causes your brother to stumble. ⁵ 

[2:19]  ¹ tn This verb is parallel to the verbs in vv. 17-18a, so it shares the conditional meaning even though the word “if” is not repeated.

[2:21]  ² tn The structure of vv. 21-24 is difficult. Some take these verses as the apodosis of the conditional clauses (protases) in vv. 17-20; others see vv. 17-20 as an instance of anacoluthon (a broken off or incomplete construction).

[2:22]  ³ tn Or “detest.”

[2:24]  ⁴ sn A quotation from Isa 52:5.

[14:21]  ⁵ tc A large number of mss, some of them quite important (Ì^46vid א² B D F G Ψ 0209 33 1881 Ï lat sa), read “or to be offended or to be made weak” after “to stumble.” The shorter reading “to stumble” is found only in Alexandrian mss (א* A C 048 81 945 1506 1739 pc bo). Although external evidence favors inclusion, internal evidence points to a scribal expansion, perhaps reminiscent of 1 Cor 8:11-13. The shorter reading is therefore preferred.
