1 Samuel 19:8

4 Then Jonathan spoke well of David to his father Saul and said to him, “The king should not sin against his servant David; he has not sinned against you. In fact, his actions have been highly beneficial to you.

5 He took his life in his hands when he struck down the Philistine, and the LORD worked a great salvation for all Israel. You saw it and rejoiced, so why would you sin against innocent blood by killing David for no reason?”

6 Saul listened to the voice of Jonathan and swore an oath: “As surely as the LORD lives, David will not be put to death.”

7 So Jonathan summoned David and told him all these things. Then Jonathan brought David to Saul to serve him as he had before.

8 When war broke out again, David went out and fought the Philistines and struck them with such a mighty blow that they fled before him.

9 But as Saul was sitting in his house with his spear in his hand, a spirit of distress from the LORD came upon him. While David was playing the harp,

10 Saul tried to pin him to the wall with his spear. But the spear struck the wall and David eluded him, ran away, and escaped that night.

11 Then Saul sent messengers to David’s house to watch him and kill him in the morning. But David’s wife Michal warned him, “If you do not run for your life tonight, tomorrow you will be dead!”

12 So Michal lowered David from the window, and he ran away and escaped.
