tc Most mss (א2 A P 𝔐) add ὑπὲρ ἡμῶν (huper hēmōn, “for us”); others (א* 69 1505 pc) add ὑπὲρ ὑμῶν (huper humōn, “for you”), the first hand of א also has ἀποθανόντος (apothanontos, “since he died”) instead of παθόντος (pathontos, “since he suffered”). But the reading without ὑπὲρ ἡ/ὑμῶν best explains the rise of the other readings, for not only is there confusion as to which pronoun belongs here, but the longer readings, being clarifications, are evidently motivated readings. The shortest reading is found in important and early Alexandrian and Western witnesses (𝔓72 B C Ψ 0285 323 1739) and is strongly preferred.

sn Has finished with sin. The last sentence in v. 1 may refer to Christ as the one who suffered in the flesh (cf. 2:21, 23; 3:18; 4:1a) and the latter part would then mean, “he has finished dealing with sin.” But it is more likely that it refers to the Christian who suffers unjustly (cf. 2:19–20; 3:14, 17). This shows that he has made a break with sin as vs. 2 describes.
