Once upon a time God was looking for a new King of Israel to replace the one then. He sent his servant Jesse to the house of Samuel to get someone!
Once he got there, he talked to Samuel asking to anoint one of his sons and David the youngest was chosen.
However, the king was NOT happy with this because he wanted to feel like God.
Although there was always a massive war going on between the Philistines and Israelites, one Philistine was a HUGEEE 9 ft Warrior named Goliath and no one had the courage to battle him until David!
So David took out his mighty slingshot, and picked up some tiny rocks off the ground. Goliath was not afraid until David flung the rocks at Goliath's head, and he fell over. David took his head with him.
And the story comes to an end and happiness is gained...
