1 Samuel 26:21-25

Then Saul said, “I have sinned. Come back, David my son. Because you considered my life precious today, I will not try to harm you again. Surely I have acted like a fool and have been terribly wrong.” “Here is the king’s spear,” David answered. “Let one of your young men come over and get it. The LORD rewards everyone for their righteousness and faithfulness. The LORD delivered you into my hands today, but I would not lay a hand on the LORD’s anointed. As surely as I valued your life today, so may the LORD value my life and deliver me from all trouble.” Then Saul said to David, “May you be blessed, David my son; you will do great things and surely triumph.” So David went on his way, and Saul returned home.
