15:9 The Philistines came up, pitched camp in Yehuda
The land of Yehuda encompasses much of the biblical heartland of Eretz Yisrael. Chevron and Beit Lechem are in the heart of the territory of Yehuda, while Yerushalayim is on its border. Though it borders both Yehuda and Binyamin, the Talmud (Yoma 12a) states that Yerushalayim was not given to a specific tribe; rather, it belongs to all of Israel. The holiness of the city chosen by God (Deuteronomy 12:5) is a unifying force that joins everyone together in the service of the Almighty.
THEN THE ARMY OF THE PHILISTINES CAME UP AND CAMPED IN THE TRIBAL TERRITORY OF JUDAH AND OVERRAN LEHI JAWBONE.
