'Burden' in the Bible

and when I was present with you and was in need, I was not a burden to anyone; for when the brethren came from Macedonia they fully supplied my need, and in everything I kept myself from being a burden to you, and will continue to do so.

For in what respect were you treated as inferior to the rest of the churches, except that I myself did not become a burden to you? Forgive me this wrong!

Here for this third time I am ready to come to you, and I will not be a burden to you; for I do not seek what is yours, but you; for children are not responsible to save up for their parents, but parents for their children.

But be that as it may, I did not burden you myself; nevertheless, crafty fellow that I am, I took you in by deceit.
