1 Samuel 17:34-40

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!” Then Saul outfitted David as a soldier in armor. He put his bronze helmet on his head and belted his sword on him over the armor. David tried to walk but he could hardly budge. David told Saul, “I can’t even move with all this stuff on me. I’m not used to this.” And he took it all off. Then David took his shepherd’s staff, selected five smooth stones from the brook, and put them in the pocket of his shepherd’s pack, and with his sling in his hand approached Goliath.
