Samuel Summary - end

Chapter 24
David doesn't kill Saul when he has a chance, and points it out to Saul.
Saul responds well verbally, even saying David will be the next king, and asking his mercy.
Future events in chapter 26 show his hypocrisy, though.

25
David is spurned by Nabal, whose flocks David's men protected.  David plans a disproportionate response, but Nabal's wife Abigail intervenes, giving what David asked for, and speaking wisely to dissuade David.  Nabal dies soon after, and David proposes to Abigail.  He now has 3 wives: Michal, Abigail, and Ahinoam.

26
Chapter 24 repeats, but David is more pro-active in making it happen, and makes a stronger appeal.  Saul has less to say, and is in a weaker position than before.  David continues to be tempted to unnecessary violence by his own men.

27
David goes to Philistine territory to live, pretending to them that he is opposed to and attacking Israel.

28
The Philistines gather to attack Israel.  Saul out of fear goes to a witch for guidance, since God doesn't answer him.  Samuel says he'll be dead in a day, and Israel defeated.  Saul eats an anti-Passover with unleavened bread, before Israel's defeat (not deliverance), as Israel's unfaithful leader Moses.

29
The Philistines don't let David go into battle with them, afraid he might turn on them, which he probably would have.  David wisely protests to Achish, else it'd look suspicious, then goes home.

30
But his home was raided, and all the people and goods carried off.  David pursues after seeking God's blessing, and recovers it all.  He shows wisdom in ruling, unlike Saul.

31
The Philistines attack, win, and kill Saul and his 3 oldest sons, including Jonathan.
