we did not eat anyone's bread free of charge; instead, we labored and toiled, working night and day, so that we would not be a burden to any of you.
It is not that we don't have the right [to support], but we did it to make ourselves an example to you so that you would imitate us.
In fact, when we were with you, this is what we commanded you: "If anyone isn't willing to work, he should not eat."
For we hear that there are some among you who walk irresponsibly, not working at all, but interfering with the work [of others].
Now we command and exhort such people, by the Lord Jesus Christ, that quietly working, they may eat their own bread.
