King Saul announced that whoever kills this Philistine- will receive greatness and become the king's son in law everyone was afraid-they saw Goliath's size- his armor, no one wanted to face him when David came- he wasn't even a soldier, his brothers were soldiers he was a shepherd- a simple boy whose father sent him to deliver some snacks to his brothers in the battlefield, when he visited the camp- he heard that everyone was running away he saw Goliath come out and speak out against G-d this made David angry- he asked, who is this rude and arrogant person who's speaking this way?! when he heard that no one wants to confront Goliath, he told Saul- I will go!
