When Abigail saw David, she hurried, and alighted from her donkey, and fell before David on her face, and bowed herself to the ground.
"Let not my lord regard this fellow Nabal"  (1 Samuel 25:25).  This was exactly the same argument that David himself had used in his efforts to dissuade Saul from trying to kill David  (1 Samuel 24:14).  The argument was that Nabal was not important enough to warrant David's taking vengeance upon him; and besides, as Abigail pointed out, it was contrary to God's law for David so to do.  Here again is evidence that the Pentateuch, from cover to cover (or throughout the whole roll), was known to well-informed Israelites centuries prior to the time which some critics erroneously claim as the time when it was written!
