2 Thessalonians 3:6-7, 11

Now we command you, brethren, in the name of our Lord Jesus Christ, that you keep away from every brother who leads an unruly life and not according to the tradition which you received from us. For you yourselves know how you ought to follow our example, because we did not act in an undisciplined manner among you

For we hear that some among you are leading an undisciplined life, doing no work at all, but acting like busybodies.
