Romans 2:21

2:21 therefore ¹  you who teach someone else, do you not teach yourself? You who preach against stealing, do you steal?

Romans 14:21

14:21 It is good not to eat meat or drink wine or to do anything that causes your brother to stumble. ² 

[2:21]  ¹ 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).

[14:21]  ² 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.
