After nine chapters of genaeology, we get to historical narrative.
It’s the story of the death of king Saul, he killed himself when all was lost after his sons were killed in a battle with the Philistines.
No hint as is told in Samuel of what a beautiful soul Jonathon was.
The emphasis here is that his line ended, snuffed out in a single battle. It’s described as God’s punishment for not being faithful to the Lord particularly for looking for guidance from the spirit world.
Definately the headline version, given what a tortured soul he was, and the epic and unusual struggle between him and David.
David’s faithfulness in that story made it spiritual, made it about Saul and God, because David would not fight. He’s a big part of the reason there is no ambiguity about Saul’s sin.
