3:6 But we command you, brothers and sisters, ¹  in the name of our Lord Jesus Christ, to keep away from any brother who lives an undisciplined ²  life ³  and not according to the tradition they ⁴  received from us. 3:11 For we hear that some among you are living an undisciplined life, ⁵  not doing their own work but meddling in the work of others. ⁶  3:14 But if anyone does not obey our message through this letter, take note of him and do not associate closely with him, so that he may be ashamed.
