Until now no one has outlined the matrimonial politics of the Davidic dynasty as a whole. A closer look reveals these policies to be a clear-cut means of stabilizing David's dynasty and expanding its territory and power. As far as we know, all of the marriages of Davidic crown-princes are comprehensible in the political and regional context of the time. In every case, choosing the bride for the crown-prince of Jerusalem and Judah was politically goal oriented. Selection of the royal bride throws light on the sometimes weaker, sometimes stronger (more independent) position of the kings as well as the possibilities and aims of Davidic politics. Mentioning the kings's mothers makes clear that the Bible can supply valuable information for the investigation of the history of Israel and Judah.
