'Hard' in the Bible

But you are turned out of the way; you have made the law hard for numbers of people; you have made the agreement of Levi of no value, says the Lord of armies.

And I will come near to you for judging; I will quickly be a witness against the wonder-workers, against those who have been untrue in married life, against those who take false oaths; against those who keep back from the servant his payment, and who are hard on the widow and the child without a father, who do not give his rights to the man from a strange country, and have no fear of me, says the Lord of armies.

Hard against Me have been your words, Said Jehovah, and ye have said: 'What have we spoken against Thee?'
