'Burden' in the Bible

and when I was present with you and was in want, I was not a burden on any man; for the brethren, when they came from Macedonia, supplied the measure of my want; and in everything I kept myself from being burdensome unto you, and'so will I keep myself .

For what is there wherein ye were made inferior to the rest of the churches, except it be 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 yours, but you: for the children ought not to lay 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 guile.
