2 Thessalonians 3:7-9

3:7 For you know yourselves how you must imitate us, because we did not behave without discipline among you, 3:8 and we did not eat anyone’s food without paying. Instead, in toil and drudgery we worked night and day in order not to burden any of you. 3:9 It was not because we do not have that right, but to give ourselves as an example for you to imitate.
