'They Were Afraid' in the Bible

And he said unto his brothers, My money is restored; and, lo, it is even in my sack: and their hearts failed them, and they were afraid, saying one to another, What is this that God has done unto us?

And it came to pass as they emptied their sacks, that, behold, every man's bundle of money was in his sack: and when both they and their father saw the bundles of money, they were afraid.
