'Hard' in the Bible

"Does not humanity have hard service on earth? Are not their days also like the days of a hired man?

My flesh is covered with worms and dust; my skin gets hard and then is cracked again.

So that a hard death seems better to my soul than my pains.

He is wise in heart and great in strength: who ever made his face hard against him, and any good came of it?

Was I not drained out like milk, becoming hard like cheese?

Will you be hard on a leaf in flight before the wind? will you make a dry stem go more quickly on its way?

If a man dies, will he live again? All the days of my hard service I will wait until my release comes.

It would not be hard for me to say such things if your souls were in my soul's place; joining words together against you, and shaking my head at you:

Even today my outcry is bitter; his hand is hard on my sorrow.

He puts his hand on the hard rock; he overturns mountains by [the] roots.

You have become cruel to me; the strength of your hand is hard on me.

Have I not wept for those who have fallen on hard times?Has my soul not grieved for the needy?

Fear of me will not overcome you, and my hand will not be hard on you.

Because the hand of the cruel is hard on them, men are making sounds of grief; they are crying out for help because of the arm of the strong.

can you help God spread out the skiesas hard as a cast metal mirror?

when water becomes as hard as stone,and the surface of the watery depths is frozen?

When the earth becomes hard as metal, and is joined together in masses?

Can you depend on it because its strength is great?Would you leave it to do your hard work?

His heart is as firm as a stone; yea, as hard as a piece of the nether millstone.
