Here was a world, with some of its constituents wedged pretty firmly by mutual pressure, but in the main broken and restless--a political surface that was always changing. The whole was subject to the movements of the two empires at its extremes. One of them could not move without sending a thrill through to the borders of the other. The approximate distances were these:--from Egypt's border to Jerusalem, about one hundred miles; from Jerusalem to Samaria, forty-five; from Samaria to Damascus, one hundred and fifteen; from Damascus to Hamath, one hundred and thirty; and from Hamath to the Euphrates, one hundred; in all from the border of Egypt to the border of Assyria four hundred and ninety English statute miles. The main line of war and traffic, coming up from Egypt, kept the coast to the plain of Esdraelon, which it crossed towards Damascus, travelling by the north of the sea of Galilee, _the way of the sea_. Northern Israel was bound to fall an early prey to armies, whose easiest path thus traversed her richest provinces. Judah, on the other hand, occupied a position so elevated and apart, that it was likely to be the last that either Assyria or Egypt would achieve in their subjugation of the States between them. Thus, then, Western Asia spread itself out in Isaiah's day. Let us take one more rapid glance across it. Assyria to the north, powerful and on the offensive, but hampered by Babylon; Egypt on the south, weakened and in reserve; all the cities and States between turning their faces desperately northwards, but each with an ear bent back for the promises of the laggard southern power, and occasionally supported by its subsidies; Hamath, their advanced guard at the mouth of the pass between the Lebanons, looking out towards the Euphrates; Tyre and Sidon attractive to the Assyrian king, whose policy is ultimately commercial, by their wealth, both they and the Philistine cities obstructing his path by the coast to his great rival of Egypt; Israel bulwarked against Assyria by Hamath and Damascus, but in danger, as soon as they fall, of seeing her richest provinces overrun; Judah unlikely in the general restlessness to retain her hold upon Edom, but within her own borders tolerably secure, neither lying in the Assyrian's path to Egypt, nor wealthy enough to attract him out of it; safe, therefore, in the neutrality which Isaiah ceaselessly urges her to preserve, and in danger of suction into the whirlpool of the approach of the two empires only through the foolish desire of her rulers to secure an utterly unnecessary alliance with the one or the other of them.
