1 Samuel 26:21-25

Then Saul confessed, “I have sinned. Come back home, my son, and I will no longer try to harm you, for you valued my life today. I have been a fool and very, very wrong.” “Here is your spear, O king,” David replied. “Let one of your young men come over and get it. The LORD gives his own reward for doing good and for being loyal, and I refused to kill you even when the LORD placed you in my power, for you are the LORD’s anointed one. Now may the LORD value my life, even as I have valued yours today. May he rescue me from all my troubles.” And Saul said to David, “Blessings on you, my son David. You will do many heroic deeds, and you will surely succeed.” Then David went away, and Saul returned home.
