=War Between the Two Kingdoms.= As soon as the Egyptian forces were withdrawn, Northern Israel, by virtue of its greater resources, first recovered its strength and fortified the town of Ramah, five miles north of Jerusalem. Ramah stood on a prominent hill two thousand six hundred feet high, near the intersection of the main highways running north, south, east, and west. From this fortress it was possible to cut off all commercial relations between Judah and the north. The king of Judah retaliated by hiring the aid of the Arameans. When the Northern Israelite army was withdrawn the fortress at Ramah was razed to the ground. With materials taken from this ruin the king of Judah fortified the old stronghold of Geba, two miles to the northeast, thus gaining control of the main highway from the Jordan to the Philistine Plain. In the same way Mizpah, an imposing, massive hill to the northwest of Jerusalem, was fortified. Mizpah^{(20)} lies about two miles south of Gibeon,^{(93)} through which ran the old division line between the north and the south, so it is evident that in this border warfare the boundary between the two kingdoms remained practically the same as before. Soon both were forced to unite against their common foe, the Arameans, so that, with one disastrous exception, neither attempted again to encroach upon the territory of the other. =Amaziah's Wars.= In the division of the two kingdoms, Edom and the South Country fell to Judah. Shishak so completely weakened Judah that it appears to have early lost control of the Edomites. Amaziah, the father of Uzziah, was the first who succeeded in winning a decisive victory over these southern foes of the Hebrews. The battle was fought, as in the days of David, in the Valley of Salt, southwest of the Dead Sea. The narrative adds that he took Sela (the Rock) by storm. It is not clear whether this was a border fortress or, as many hold, Petra, the marvellous capital city of the Edomites, which lies in a narrow gorge, cut out of the heart of the many-colored limestone mountains that rise between the Ghôr and the Arabian desert.^{(50)} Elated by this victory, Amaziah foolishly challenged the king of Northern Israel to battle. The decisive engagement was fought at Beth-shemesh, the prosperous town that lay on the southern side of the Valley of Sorek. It was almost due west of Jerusalem and in the heart of the lowlands along which the northern army probably approached. Following up the victory, the Northern Israelites tore down two hundred yards of the northwestern wall of Jerusalem at the point where the city mounted the northern plateau and was, therefore, most exposed. They also looted the temple and royal palace, thus completing the humiliation of the southern kingdom. The conspiracy which resulted in the flight and execution of Amaziah at Lachish, the southwestern outpost of Judah, was probably the fruit of his folly.
