The mention of Hiram sounds like an echo of a still distant future, when construction work will unfold in Jerusalem. The account of David's growing family also speaks of that same future, when his power and position will be strengthened. For the moment, however, David's familiar military concerns take center stage: another war with the Philistines begins.
It is symbolic that the Philistines encamped in the Valley of Rephaim, the ancient fearsome giants. But giants do not frighten David, and not only because he has already once struck down one of them, Goliath. Far more important is the fact that this war is not merely another clash between two armies, but one more battle against militant paganism; therefore the Lord is on David's side.
On the Philistines' side are their gods, who did not help them. Their idols, abandoned by the retreating army, proved unnecessary even to those who worshiped them. All the more were they unnecessary to the victors: no place was found for them even among the spoils.

His wives and children, Ch1 14:3-7.
His victories over the Philistines, Ch1 14:8-17.
