1 Samuel 17:31-37

The things David was saying were picked up and reported to Saul. Saul sent for him. “Master,” said David, “don’t give up hope. I’m ready to go and fight this Philistine.” Saul answered David, “You can’t go and fight this Philistine. You’re too young and inexperienced—and he’s been at this fighting business since before you were born.” David said, “I’ve been a shepherd, tending sheep for my father. Whenever a lion or bear came and took a lamb from the flock, I’d go after it, knock it down, and rescue the lamb. If it turned on me, I’d grab it by the throat, wring its neck, and kill it. Lion or bear, it made no difference—I killed it. And I’ll do the same to this Philistine pig who is taunting the troops of God-Alive. GOD, who delivered me from the teeth of the lion and the claws of the bear, will deliver me from this Philistine.” Saul said, “Go. And GOD help you!”
