Certainly, it is essential to grasp the intricacies of Davi's initial story, constructing a conceptual framework that allows for the gradual addition of historical components, ultimately leading to a comprehensive understanding of the entirety.
It is crucial to understand that initially, Prophet Samuel seemed to disdain David in 1 Samuel 16:12. The prophet expressed his refusal to sit at the table until the youngest son of Jesse arrived. During this interval, it is plausible that he heard narratives reflecting a similar tone of disdain, as the one recounted in 1 Samuel 17:28 and ended up sitting down, being warned by God to get up.
The story of David and Goliath, found in the book of 1 Samuel 17:3, is often misunderstood. In the context, Israel and the Philistines were positioned on opposite sides of two hills, with a deep divide in between. David, with great courage, descended into the valley to face Goliath. At the crucial moment of the confrontation in 1 Samuel 17:43, Goliath surprisingly underestimated David's choice of a sling and five stones, mistaking it for a mere piece of wood.
Certainly, it is plausible to imagine that Goliath's squire, having escaped and witnessed the epic turn of events, likely recounted the astonishing tale to King Philistine later. In that pivotal moment, both nations gazed in awe from the distant hills as they witnessed the remarkable sight of a fearless young man triumphantly holding the severed head of Goliath.
At this point, we already know that David had a place at Saul's table as a military member, as mentioned in 1 Samuel 20:5. The Bible does not explicitly state the reason for the first persecution of David; however, David indirectly hints at the reasons behind it.
Certainly, it is plausible to consider that David may have shown mercy to invaders in some battle, given the unfolding of the story we know about him. This possibility gains strength when we examine the episode involving the Philistines, as compassionate actions were distinctive traits of David, as evidenced, for example, in 1 Samuel 30:11-15.
Psalm 109:4 King James Version
For my love they are my adversaries: but I give myself unto prayer.
Psalm 69:4 New International Version
Those who hate me without reason outnumber the hairs of my head; many are my enemies without cause, those who seek to destroy me. I am forced to restore what I did not steal.
However, this strategic act of compassion may have been misunderstood by the military and King Saul. David's insight in acting with love and understanding may have been viewed with suspicion, especially in a military context where fierceness was often considered a virtue. This potential misinterpretation, combined with Saul's longstanding animosity towards David, exacerbated by the fact that David did not use a sword to defeat Goliath, may have contributed to the rising anger of both the military and the king.
With all these unfavorable events for David, it is plausible to suggest that he came to be perceived as a "traitor" to the Jews. This view may have been reinforced by the notion that David was "mad," a fact that could have contributed to his survival while sojourning among the Philistines. These potential reasons explain why David was not killed by the Philistines, despite the adverse circumstances and the growing tensions surrounding him.
