The royalty of the north did not spring up through long years of gradual ascendency, and could not originally appeal to splendid services and heroic memories. Jeroboam was a man of humble, and, if tradition says truly, of tainted origin. He was not a usurper, for he was called to the throne by the voice of prophecy and the free spontaneous choice of his people; but in Solomon's days he had been a potential if not an actual rebel. He set the example of successful revolt, and it was eagerly followed by many a soldier and general of similar antecedents. In the short space of two hundred and forty-five years there were no less than nine changes of dynasty, of which those of Jeroboam, Baasha, Kobolam,[464] Menahem, consisted only of a father and son. There were at least four isolated or partial kings: Zimri, Tibni, Pekah, and Hosea. Only two dynasties, those of Omri and Jehu, succeeded in maintaining themselves for even four or five generations, and they, like the others, were at last quenched in blood. The close of the kingdom in its usurpations, massacres, and catastrophes reminds us of nothing so much as the disastrous later days of the Roman Empire, when the purple was so often rent by the dagger-thrust, and it was rare for emperors to die a natural death. The kingdom which had risen from a sea of blood set in the same red waves. On the other hand, whatever may have been the drawback of the small and hampered Southern Kingdom, it had several conspicuous advantages. It had a settled and incomparable capital, which could be rendered impregnable against all ordinary assaults; while the capital of the Northern Kingdom shifted from Shechem to Penuel[465] and Tirzah, and from Tirzah to Samaria and Jezreel. It had the blessing of a loyal people, and of the all-but-unbroken continuity of one loved and cherished dynasty for nearly four centuries. It had the yet greater blessing of producing not a few kings who more or less fully attained to the purity of the theocratic ideal. Asa, Jehoshaphat, Hezekiah, Josiah, were good and high-minded kings, and the two latter were religious reformers. Whatever may have been the sins and shortcomings of Judah--and they were often very heinous--still the prophets bear witness that her transgressions were less incurable than those of her sister Samaria. All good men began to look to Jerusalem as the nursing mother of the Promised Deliverer. "Out of Judah," said the later Zechariah, "shall come forth the corner stone, out of him the nail, out of him the battle bow, out of him every governor together."[466] Amos was born in Judah; Hoshea took refuge there; the later Zechariah laboured (ix., xi., xiii. 7-9) for the fusion of the two kingdoms. From the unknown, or little known, seers who endeavoured to watch over the infant destinies of Judah, to the mighty prophets who inspired her early resistance to Assyria, or menaced her apostasy with ruin at the hands of Babylon, she rarely lacked for any long period the inspired
