1. Help to defeat the Ammonites (1-3)

In this short chapter, the Chronicler omits many events, including David's sin of adultery and Absalom's conspiracy (2Sa 11-21). When David should've been fighting the Lord's battles, he was relaxing in Jerusalem. But Joab fought and defeated the Ammonites at Rabbah. David joined the battle and got the crown. We should not let down our guard, but keep a fighting spirit against the devil. We should also thank God for others who faithfully fight the Lord's battles.

2. Help to defeat the Philistines (4-8)

Sibbekai, Elhanan and Jonathan were three Israelite men who fought bravely and defeated big, scary Philistine enemies. Again, David was helped by valiant men. God gave Israel victories for the sake of his name and his people.
