'Burden' in the Bible

For this our light and transitory burden of suffering is achieving for us a preponderating, yes, a vastly preponderating, and eternal weight of glory;

And when I was with you and my resources failed, there was no one to whom I became a burden--for the brethren when they came from Macedonia fully supplied my wants--and I kept myself from being in the least a burden to you, and will do so still.

If I love you so intensely, am I the less to be loved? Be that as it may: I was not a burden to you. But being by no means scrupulous, I entrapped you, they say!
