1 Samuel 17:34-36

34But David persisted. “I have been taking care of my father’s sheep and goats,” he said. “When a lion or a bear comes to steal a lamb from the flock,

35I go after it with a club and rescue the lamb from its mouth. If the animal turns on me, I catch it by the jaw and club it to death.

36I have done this to both lions and bears, and I’ll do it to this pagan Philistine, too, for he has defied the armies of the living God!
