David flees into the wilderness, where he gathers a band of followers and becomes the champion of the oppressed while evading the pursuit of Saul. He accepts the town of Ziklag as a fief from the Philistine king Achish of Gath, but continues secretly to champion the Israelites. Jonathan and Saul are killed in battle with the Philistines at Mount Gilboa. David mourns their deaths, especially that of Jonathan, his friend. He goes up to Hebron, where he is anointed king over Judah. In the north, Saul's son Ish-Bosheth becomes king of the tribes of Israel. War ensues between Ish-Bosheth and David, until Ish-Bosheth is murdered. The assassins bring the head of Ish-Bosheth to David hoping for reward, but David executes them for their crime against the Lord's anointed. Yet with the death of the son of Saul, the elders of Israel come to Hebron and David, who is 30 years old, is anointed King over Israel and Judah.
