'Burden' in the Bible

When I was with you and was in need, I was not a burden to anyone, for the brothers who came from Macedonia fully supplied my needs. I kept myself from being a burden to you in any way, and will continue to do so.

For how were you treated worse than the other churches, except that I myself was not a burden to you? Forgive me this injustice!

Look, for the third time I am ready to come to you, and I will not be a burden to you, because I do not want your possessions, but you. For children should not have to save up for their parents, but parents for their children.
