'Burden' in the Bible

When I was present with you and was in need, I wasn't a burden on anyone, for the brothers, when they came from Macedonia, supplied the measure of my need. In everything I kept myself from being burdensome to you, and I will continue to do so.

For what is there in which you were made inferior to the rest of the assemblies, unless it is that I myself was not a burden to you? Forgive me this wrong.

Behold, this is the third time I am ready to come to you, and I will not be a burden to you; for I seek not your possessions, but you. For the children ought not to save up for the parents, but the parents for the children.

But be it so, I did not myself burden you. But, being crafty, I caught you with deception.
