1 Samuel 19:1-4

Now Saul told his son Jonathan and all his servants to kill David, but Jonathan, Saul’s son, greatly delighted in David. So he told David, “Saul my father is seeking to kill you. Now then, please be on guard in the morning, and stay in a secret place and hide yourself. As for me, I will go out and stand beside my father in the field where you are, and I will speak with my father about you, and if I learn anything, then I will tell you.” Then Jonathan spoke well of David to Saul his father and said to him, “May the king not sin against his servant David, since he has not sinned against you, and since his deeds have been very beneficial to you.
