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?"
"There is but a step between me and death"  (1 Samuel 20:3).  David reinforced his words with a double oath, and provided Jonathan with the real reason why he had not been taken into the king's confidence in the matter of his decision to kill David.  That reason was the king's knowledge that Jonathan, through his friendship for David, would not have approved of it.
