1 Samuel 26:23-25

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.
