⁶Now we command you, brothers, ^ain the name of our Lord Jesus Christ, that you ¹^,^bkeep away from every brother who walks in an ²^,^cunruly manner and not according to ^dthe tradition which ³they received from us.

¹⁴And if anyone does not obey our word ¹^,^ain this letter, take special note of that person ^bto not associate with him, so that he will be ^cput to shame. ¹⁵And yet ^ado not regard him as an enemy, but ¹^,^badmonish him as a ^cbrother.
