Saul Persecutes David (1 Samuel 19)

        but Jonathan, Saul's son, delighted much in David.  So Jonathan told David, saying, "My father Saul seeks to kill you.  Therefore please be on your guard until morning, and stay in  a secret place and hide.  "And I will go out and stand beside my father in the field where you are, and I will speak with my father about you.  Then what I observe, I will tell you,"  Now Jonathan spoke well of David to Saul, and said to him, "Let not the king sin against his servant, against David, because you, and because his works have been very toward you.
