It was a difficult and arduous task that he accepted without fanfare.

I attempt an arduous task; but there is no worth in that which is not a difficult achievement.

It is easy at any moment to surrender a large fortune; to build one up is a difficult and an arduous task.

The search for knowledge is a long and difficult task.

It is an easy and vulgar thing to please the mob, and no very arduous task to astonish them

A Fanfare for Peter.
