David's career is described principally in the biblical books of Samuel, which portray his rise from service under Saul to kingship over Judah and Israel. Those narratives combine political memory, literary construction, and theological interpretation, and their detailed events cannot all be verified independently.

In the narrative, David gains recognition through military success, including the encounter with Goliath, and develops a close relationship with Saul's son Jonathan. Saul's jealousy turns him into a fugitive and rival, leading to shifting alliances and periods outside royal control. After Saul's death, David rules first from Hebron and later gains authority over a wider kingdom. The capture of Jerusalem and its establishment as a capital create a central political and religious setting. Bringing the Ark there connects the monarchy to worship, while military campaigns depict the extension of royal power.

The same account presents serious abuses and family conflict. The Bathsheba episode describes David taking Uriah's wife and arranging the circumstances of Uriah's death, followed by prophetic condemnation. Conflict among his children and Absalom's rebellion undermine the household and kingdom. These stories complicate the portrait of an ideal ruler rather than functioning only as praise. In the succession narrative, court factions and promises concerning Solomon determine the transfer of power. Later biblical traditions associate David with psalms and preparations for the Temple, but those associations do not prove his personal authorship of every attributed poem or establish every claimed building plan.

The Tel Dan inscription, from the ninth century BCE, is widely understood to refer to the House of David, providing important evidence for a dynasty identified by his name. It does not directly confirm the Goliath encounter, the family episodes, or the full territorial scale described in Samuel. Archaeological interpretations of early Jerusalem and other proposed royal sites remain debated. David became a figure in Jewish, Christian, and Islamic traditions, with his kingship shaping religious expectations and cultural representations. His significance in those traditions is clear even where his recoverable political biography remains limited. A historically careful account distinguishes the dynasty's external attestation from the richer biblical portrait and keeps both the narrative's achievements and its criticism of royal wrongdoing visible.
