1 Samuel 20:2-3

2“Never!” he said to him. “You will not die! Behold, my father does nothing great or small without disclosing it to me. So why should my father hide this matter from me? It cannot be.”

3Then David swore again saying, “Your father knows very well that I have found favor in your eyes. So he must have thought, ‘Let’s not let Jonathan know about this, else he will be grieved.’ But truly as Adonai lives and as your soul lives, there is but a step between me and death.”
