It was not till after the overthrow of the Ten Tribes that the glory of prophecy migrated southwards, and Jerusalem produced the mighty triad of Isaiah, Jeremiah, and Ezekiel. For the two and a half centuries that the Northern Kingdom lasted scarcely one prophet is heard of in Judah except the scarcely known Hanani, and Eliezer, the son of Mareshah,[462] who is little more than a _nominis umbra_. To the north belongs the great herald-prophet of the Old Dispensation, the mighty Elijah; the softer spirit of the statesman-prophet Elisha; the undaunted Micaiah, son of Imlah; the picturesque Micah; the historic Jonah; the plaintive Hosea; and that bold and burning patriot, a fragment of whose prophecy now forms part of the Book of Zechariah. Amos, indeed, belonged by birth to Tekoa, which was in Judah, but his prophetic activity was confined to Bethel and Jezreel. The Schools of the Prophets at Ramah, Bethel, Jericho, and Gilgal were all in Israel. The passages in the third section of the Book of Zechariah are alone sufficient to show how vast was the influence in the affairs of the nation of the prophets of the north, and how fearless their intervention. Even when they were most fiercely persecuted, they were not afraid to beard the most powerful kings--an Ahab and a Jeroboam II.--in all their pride.[463] Samaria and Galilee were rich in prophetic lives; and they, too, were the destined scene of the life of Him of whom all the prophets prophesied, and from whose inspiration they drew their heavenly fire. Against these advantages, however, must be set two serious and ultimately fatal drawbacks--germs of disease which lay in the very constitution of the kingdom, and from the first doomed it to death. One of these was the image-worship, of which I shall speak in a later section; the other was the lack of one predominant and continuous dynasty.
