'Hard' in the Bible

And it will be, in the day when the Lord gives you rest from your sorrow, and from your trouble, and from the hard yoke which they had put on you,

And I will give the Egyptians into the hand of a cruel lord; and a hard king will be their ruler, says the Lord, the Lord of armies.

I have long been quiet, I have kept myself in and done nothing: now I will make sounds of pain like a woman in childbirth, breathing hard and quickly.

Because I saw that your heart was hard, and that your neck was an iron cord, and your brow brass;

And I will put it into the hand of your cruel masters, and of those whose yoke has been hard on you; who have said to your soul, Down on your face! so that we may go over you: and you have given your backs like the earth, even like the street, for them to go over.

O Lord, why do you send us wandering from your ways, making our hearts hard, so that we have no fear of you? Come back, because of your servants, the tribes of your heritage.
