I think this has struck me before. Re-reading 1 Samuel, we find that:
- Saul is rebuked by Samuel (1 Samuel 15)
- David has to flee to the Philistines (1 Samuel 21)
- David lives among the Philistine (1 Samuel 27)
- Saul is rebuked by Samuel (1 Samuel 28)
Now: I know …: Chiasms are a little like white elephants, and if you're not careful you start to see them everywhere.
But, it does seem that chapter 25 is a key chapter, making those two events (the death of Samuel, and the death of Nabal) key events in the episode that is David's flight from Saul. They may offer a clue as to the purpose of the lengthy record we have of that period of David's life. The question is: What clue? Comments please!
