Forgot one other thing -
2 Thessalonians 3:8, "Neither did we eat any man's bread for nought; but wrought with labour and travail night and day, that we might not be chargeable to any of you."
Looks like maybe Paul worked in addition to his ministry, in order to avoid being a burden on the churches. Never noticed that one before either.
Paul was a tent-maker. Don't know the scripture, but I'll look it up.
Acts 18:2-3
Paul went to see them, and because he was a tent-maker as they were, he stayed and worked with them.
