2 Thessalonians 3:7-9

7For you yourselves know how you ought to follow our example. We were not idle when we were with you, 8nor did we eat anyone’s food without paying for it. On the contrary, we worked night and day, laboring and toiling so that we would not be a burden to any of you. 9We did this, not because we do not have the right to such help, but in order to offer ourselves as a model for you to imitate.
