1 Samuel 19:1-10 NASB1995
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.
When there was war again, David went out and fought with the Philistines and defeated them with great slaughter, so that they fled before him. Now there was an evil spirit from the LORD on Saul as he was sitting in his house with his spear in his hand, and David was playing the harp with his hand. Saul tried to pin David to the wall with the spear, but he slipped away out of Saul’s presence, so that he stuck the spear into the wall. And David fled and escaped that night.
