As already indicated the chapter break is unfortunate, since this verse provides the conclusion of the section dealing with the war between Israel and Judah.

There was a long war: the idea here is that beginning at that time there was long conflict. One way of saying this is as in New American Bible, “there followed a long war….” Or, in order to show that the previously described battle was also considered a part of this long period of conflict between the two groups, “So the war dragged on” (New Jerusalem Bible) or “This battle was the beginning of a long war…” (Contemporary English Version).

House of Saul … house of David: as often in the Bible, the word house in such a context refers to the families of the individuals named. In most languages it will be better to translate “family” rather than using the literal rendering “house.” But in this context the word house may be intended to convey a broader meaning. Bible en français courant and Die Bibel im heutigen Deutsch speak of the “partisans of Saul and those of David,” and this seems to express the intended sense of the Hebrew. Nova Tradução na Linguagem de Hoje and Good News Translation speak of those who supported the families of Saul and of David, and this model is also acceptable.

David grew stronger: perhaps intentionally the writer does not repeat the expression the house of David but rather refers to David as an individual. But this does not refer to his physical strength. He grew stronger politically and so his whole group became stronger. Note also that, while the text repeats the house of Saul here, Good News Translation keeps the focus on David and translates “his opponents.”
