1 Sam 17:32-36 NLT

“Don’t worry about a thing,” David told Saul. “I’ll go fight this Philistine!” “Don’t be ridiculous!” Saul replied. “There is no way you can go against this Philistine. You are only a boy, and he has been in the army since he was a boy!” But David persisted. “I have been taking care of my father’s sheep,” he said. “When a lion or a bear comes to steal a lamb from the flock, I go after it with a club and take the lamb from its mouth. If the animal turns on me, I catch it by the jaw and club it to death. I 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! (1 Sam 17:32-36 NLT)
