'Rough' in the Bible

Then David said to Jonathan, Who will give me word if your father gives you a rough answer?

(now the man’s name was Nabal and his wife’s name was Abigail. She was intelligent and beautiful in appearance, but the man was harsh and evil in his dealings; he was a Calebite).

But one of the young men said to Nabal's wife Abigail, David sent men from the waste land to say kind words to our master, and he gave them a rough answer.
