1 Samuel 19:1-7

Now Saul told Jonathan his son and all his servants to put David to death. But Jonathan, Saul’s son, greatly delighted in David. So Jonathan told David saying, “Saul my father is seeking to put you to death. Now therefore, please be on guard in the morning, and stay in a secret place and hide yourself. I will go out and stand beside my father in the field where you are, and I will speak with my father about you; if I find out anything, then I will tell you.” Then Jonathan spoke well of David to Saul his father and said to him, “Do not let the king sin against his servant David, since he has not sinned against you, and since his deeds have been very beneficial to you. For he took his life in his hand and struck the Philistine, and the LORD brought about a great deliverance for all Israel; you saw it and rejoiced. Why then will you sin against innocent blood by putting David to death without a cause?” Saul listened to the voice of Jonathan, and Saul vowed, “As the LORD lives, he shall not be put to death.” Then Jonathan called David, and Jonathan told him all these words. And Jonathan brought David to Saul, and he was in his presence as formerly.
