Final answer:
King David is seen as a 'Man of God' in the Bible, with Saul affirming his godly nature. The Tel Dan stele provides archaeological evidence of David's existence. David established Jerusalem as a religious and political capital, which supports the divine aspects of his rule.
Step-by-step explanation:
The student's question pertains to the biblical figure David and whether he can be considered a 'Man of God,' with reference to the evidence provided by Witness 3: Saul. The Bible, as a historical and religious document, depicts David as a person exhibiting divine qualities and a godly nature, both of which are acknowledged by Saul. Archaeological evidence such as the Tel Dan stele provides some historical context to King David's existence, mentioning the "house of David", and indicating a kingdom associated with his name. Furthermore, the account of David making Jerusalem the capital and establishing a shrine there to the Israelite god Yahweh reinforces the view of David being a man connected with divinity. However, Saul's own biblical journey, which includes his conversion to Christianity, is distinct from that of King David, and so, while Saul's testament to David's nature may be valuable, it is also necessary to interpret it within the broader biblical and historical context. Therefore, the claim that David is a Man of God is supported by both David's divine qualities exhibited in the Bible and Saul's testimony of David�s godly nature, culminating in option (d) being the main answer.
