The population of Israel was comprised of 12 Tribes. According to the Tanakh, Saul was the son of Kish, of the tribe of the Matrites, and a member of the tribe of Benjamin, one of the twelve Tribes of Israel. It seems that he arrived from Gibeah. Saul perishes in the fight against the Philistines following a rule of the only couple of years. His successor, Ishbaal, governs for only two years before being killed. David, formerly ruler of Judah particularly, concludes the intrigue and is designated ruler of Israel in Ishbaal's position.
