2 Thessalonians 3:8-9

nor did we eat anyone’s bread without paying for it, but with labor and hardship we worked night and day [to pay our own way] so that we would not be a financial burden on any of you [for our support]; not because we do not have a right to such support, but [we provided our own financial support] to offer ourselves as a model for you, so that you would follow our example.
