David, son of Jesse, was the youngest of eight sons and was a shephred.
One day, his father Jesse told him to carry some food to his brother who were soldiers in the war against the philistines.
When David arrived there, he saw they were fleeing in fear because a giant man named Goliath challenged the army of Israel for a battle.
Goliath shouted: Choose your best soldier! If he overcomes me, well be your slaves! But if i overcome him, you will be our slaves!
David without fear, said to the king, God has helped me to keep my fathers sheep from a bear and a lion. Let me fight the philistine!
When Goliath saw David he despised him shouting:-Am I a dog for you to come at with a stick? David answered- You come with a sword, but i come with God, who is the Lord of the battle and who will give me the victory!
