2 Samuel 14:10-11

King David said, “Bring me anyone who says anything bad to you. Then he won’t bother you again.” The woman said, “Please promise in the name of the LORD your God. Then my relative who has the duty of punishing a murderer won’t add to the destruction by killing my son.” David said, “As surely as the LORD lives, no one will hurt your son. Not one hair from his head will fall to the ground.”
