'Hard' in the Bible

But if anyone has been a cause of sorrow, he has been so, not to me only, but in some measure to all of you (I say this that I may not be over-hard on you).

But [in fact] their minds were hardened [for they had lost the ability to understand]; for until this very day at the reading of the old covenant the same veil remains unlifted, because it is removed [only] in Christ.

Troubles are round us on every side, but we are not shut in; things are hard for us, but we see a way out of them;

hunted down and persecuted, but not deserted [to stand alone]; struck down, but never destroyed;

in beatings, imprisonments, and riots; in hard work, sleepless nights, and hunger;

Are they servants of Christ? (I am talking foolishly) I am more so; I have had more experience of hard work, of prisons, of blows more than measure, of death.

in hard work and toil, through many sleepless nights, in hunger and thirst, many times without food, in cold and without enough clothing.
