'Burdens' in the Bible

Yea, they bind heavy burdens and grievous to be borne, and lay them on men's shoulders; but they themselves will not move them with their finger.

And he said, Woe unto you lawyers also! for ye load men with burdens grievous to be borne, and ye yourselves touch not the burdens with one of your fingers.

Bear ye one another's burdens, and so fulfil the law of Christ.
