So, in 1 Chronicles 14, we meet King David. He's chillin' in Jerusalem, thinking about how to expand Israel. He consults with God, who gives him the idea to build an army and attack the Philistines. So, David goes out and kicks some Philistine butt, and even manages to take the Ark of the Covenant from them. Take that, Philistines! So, it looks like David's got a pretty good plan, and probably won't be defeated any time soon.
