In the biblical narrative of the Books of Samuel, David is described as a young shepherd and harpist who gains fame and becomes a hero by killing Goliath. He becomes a favorite of Saul, the first king of Israel, but is forced to go into hiding when Saul suspects that David is trying to take his throne. After Saul and his son Jonathan are killed in battle, David is anointed king by the tribe of Judah and eventually all the tribes of Israel. He conquers Jerusalem, makes it the capital of a united Israel, and brings the Ark of the Covenant to the city. He commits adultery with Bathsheba and arranges the death of her husband, Uriah the Hittite. David's son Absalom later tries to overthrow him, but David returns to Jerusalem after Absalom's death to continue his reign. David desires to build a temple to Yahweh, but he is denied because of the bloodshed in his reign. He dies at age 70 and chooses Solomon, his son with Bathsheba, as his successor instead of his eldest son Adonijah. David is honored as an ideal king and the forefather of the future Hebrew Messiah in Jewish prophetic literature and many psalms are attributed to him.
