'Cannot' in the Bible

What is crooked cannot be straightened and what is lacking cannot be counted.

Whatever exists has already been named, and it is known what man is; for he cannot dispute with him who is stronger than he is.

and I saw every work of God, I concluded that man cannot discover the work which has been done under the sun. Even though man should seek laboriously, he will not discover; and though the wise man should say, “I know,” he cannot discover.
