By far the greatest event in the eighth century before Christ was the appearance of Assyria in Palestine. To Israel since the Exodus and Conquest, nothing had happened capable of so enormous an influence at once upon their national fortunes and their religious development. But while the Exodus and Conquest had advanced the political and spiritual progress of Israel in equal proportion, the effect of the Assyrian invasion was to divorce these two interests, and destroy the state while it refined and confirmed the religion. After permitting the Northern Kingdom to reach an extent and splendour unrivalled since the days of Solomon, Assyria overthrew it in 721 and left all Israel scarcely a third of their former magnitude. But while Assyria proved so disastrous to the state, her influence upon the prophecy of the period was little short of creative. Humanly speaking, this highest stage of Israel's religion could not have been achieved by the prophets except in alliance with the armies of that heathen empire. Before then we turn to their pages it may be well for us to make clear in what directions Assyria performed this spiritual service for Israel. While pursuing this inquiry we may be able to find answers to the scarcely less important questions: why the prophets were at first doubtful of the part Assyria was destined to play in the providence of the Almighty? and why, when the prophets were at last convinced of the certainty of Israel's overthrow, the statesmen of Israel and the bulk of the people still remained so unconcerned about her coming, or so sanguine of their power to resist her? This requires, to begin with, a summary of the details of the Assyrian advance upon Palestine.
In the far past Palestine had often been the hunting-ground of the Assyrian kings. But after 1100 B.C., and for nearly two centuries and a half, her states were left to themselves. Then Assyria resumed the task of breaking down that disbelief in her power with which her long withdrawal seems to have inspired their politics. In 870 Assurnasirpal reached the Levant, and took tribute from Tyre and Sidon. Omri was reigning in Samaria, and must have come into close relations with the Assyrians, for during more than a century and a half after his death they still called the land of Israel by his name.[94] In 854 Salmanassar II. defeated at Karkar the combined forces of Ahab and Benhadad. In 850, 849 and 846 he conducted campaigns against Damascus. In 842 he received tribute from Jehu,[95] and in 839 again fought Damascus under Hazael. After this there passed a whole generation during which Assyria came no farther south than Arpad, some sixty miles north of Damascus; and Hazael employed the respite in those campaigns which proved so disastrous for Israel, by robbing her of the provinces across Jordan, and ravaging the country about Samaria.[96] In 803 Assyria returned, and accomplished the siege and capture of Damascus. The first consequence to Israel was that restoration of her hopes under Joash, at which the aged Elisha was still spared to assist,[97] and which reached its fulfilment in the recovery of all Eastern Palestine by Jeroboam II.[98] Jeroboam's own relations to Assyria have not been recorded either by the Bible or by the Assyrian monuments. It is hard to think that he paid no tribute to the "king of kings." At all events it is certain that, while Assyria again overthrew the Arameans of Damascus in 773 and their neighbours of Hadrach in 772 and 765, Jeroboam was himself invading Aramean land, and the Book of Kings even attributes to him an extension of territory, or at least of political influence, up to the northern mouth of the great pass between the Lebanons.[99] For the next twenty years Assyria only once came as far as Lebanon--to Hadrach in 759--and it may have been this long quiescence which enabled the rulers and people of Israel to forget, if indeed their religion and sanguine patriotism had ever allowed them to realise, how much the conquests and splendour of Jeroboam's reign were due, not to themselves, but to the heathen power which had maimed their oppressors. Their dreams were brief. Before Jeroboam himself was dead, a new king had usurped the Assyrian throne (745 B.C.) and inaugurated a more vigorous policy. Borrowing the name of the ancient Tiglath-Pileser, he followed that conqueror's path across the Euphrates. At first it seemed as if he was to suffer check. His forces were engrossed by the siege of Arpad for three years (_c._ 743), and this delay, along with that of two years more, during which he had to return to the conquest of Babylon, may well have given cause to the courts of Damascus and Samaria to believe that the Assyrian power had not really revived. Combining, they attacked Judah under Ahaz. But Ahaz appealed to Tiglath-Pileser, who within a year (734-733) had overthrown Damascus and carried captive the populations of Gilead and Galilee. There could now be no doubt as to what the Assyrian power meant for the political fortunes of Israel. Before this resistless and inexorable empire, the people of Jehovah were as the most frail of their neighbours--sure of defeat, and sure, too, of that terrible captivity in exile which formed the novel policy of the invaders against the tribes who withstood them. Israel dared to withstand. The vassal Hoshea, whom the Assyrians had placed on the throne of Samaria in 730, kept back his tribute. The people rallied to him; and for more than three years this little tribe of highlanders resisted in their capital the Assyrian siege. Then came the end. Samaria fell in 721, and Israel went into captivity beyond the Euphrates.
