David fled from Naioth in Ramah, and came and said before Jonathan, "What have I done? What is my iniquity?" and "What is my sin before your father, that he seeks my life?"
"Far from it! ...  It is not so"  (1 Samuel 20:2).  Jonathan simply could not believe that his father was trying to kill David after that solemn oath which the king had sworn that David should not die  (1 Samuel 19:6).  As one of the king's chief advisers, Jonathan felt sure that he would have been informed of any such intention on the part of his father.
