1 Samuel 20:2-3

2“Never!” Jonathan replied. “You are not going to die! Look, my father doesn’t do anything, great or small, without letting me know. Why would he hide this from me? It isn’t so!”

3But David took an oath and said, “Your father knows very well that I have found favor in your eyes, and he has said to himself, ‘Jonathan must not know this or he will be grieved.’ Yet as surely as the Lord lives and as you live, there is only a step between me and death.”
