King Saul is chosen by God and anointed as the first king of Israel by Samuel. However, Saul disobeys God twice and is rejected as king. God then leads Samuel to anoint David, the youngest son of Jesse, as the new king. David defeats Goliath and gains fame, making Saul jealous. Saul tries to kill David, who flees and protects himself. Saul and his son Jonathan are later killed in battle. David becomes king over Judah first and then all of Israel after defeating his rivals. David establishes Jerusalem as his capital and brings the Ark of God there, unifying religious and political rule.
