Colossians 3:4 New English Translation

⁴When Christ (who is your^[a] life) appears, then you too will be revealed in glory with him.

Colossians 3:4 tc Certain mss (B^[*^] D¹ H 0278 1175 1505 1739 2464 M sy sa) read ἡμῶν (hēmōn, “our”), while others (P⁴⁶ א C D* F G P Ψ 075 33 81 1881 al latt bo) read ὑμῶν (humōn, “your”). Internally, it is possible that the second person pronoun arose through scribal conformity to the second person pronoun used previously in v. 3 (ὑμῶν) and following in v. 4 (ὑμεῖς, humeis). But in terms of external criteria, the second person pronoun has superior ms support (though there is an Alexandrian split) and ἡμῶν may have arisen through accident (error of sight) or scribal attempt to universalize the statement since all Christians have Jesus as their life. See TCGNT 557.
