Final answer:
The scriptural accounts suggest that King David established a kingdom known as the Kingdom of Israel with Jerusalem as its capital. The exact boundaries of his kingdom are not clearly defined, but it included subdued neighboring territories and was part of the united monarchy period.
Step-by-step explanation:
According to the scriptural accounts, King David, who came to power after Saul and was succeeded by his son Solomon, established a kingdom that exerted its influence from the immediate regions around Jerusalem to the broader territories that included subdued kingdoms. Despite the fact that Jerusalem was not a large city at the time, David's ability to establish a capital there and suppress surrounding kingdoms marks an important period in the history of the Hebrews known as the united monarchy period. This was a golden age during which Israel and Judah emerged as distinct entities, with the former being larger and often in conflict with the latter. The kingdom founded by David, known historically and biblically as the Kingdom of Israel, was bordered by powerful and contentious neighbors such as the Philistines, Edomites, and Ammonites. However, the exact boundaries of David's kingdom, stretching from to to, remain a topic for further historical and archaeological research, with key pieces such as the Tel Dan stele lending credence to the existence of a 'house of David'.
