Now, chs. xliii.-xlviii. are simply the elaboration and more urgent offer of all these truths, under the sense of the rapid approach of Cyrus upon Babylon. They declare again God's unity, omnipotence and righteousness, they confirm His forgiveness of His people, they repeat the laughter at the idols, they give us nearer views of Cyrus, they answer the doubts that many orthodox Israelites felt about this Gentile Messiah; chs. xlvi. and xlvii. describe Babylon as if on the eve of her fall, and ch. xlviii., after Jehovah more urgently than ever presses upon reluctant Israel to show the results of her discipline in Babylon, closes with a call to leave the accursed city, as if the way were at last open. This call has been taken as the mark of a definite division of our prophecy. But too much must not be put upon it. It is indeed the first call to depart from Babylon; but it is not the last. And although ch. xlix., and the chapters following, speak more of Zion's Restoration and less of the Captivity, yet ch. xlix. is closely connected with ch. xlviii., and we do not finally leave Babylon behind till ch. lii. 12. Nevertheless, in the meantime ch. xlviii. will form a convenient point on which to keep our eyes. Cyrus, when we last saw him, was upon the banks of the Halys, 546 B.C., startling Crœsus and the Lydian Empire into extraordinary efforts, both of a religious and political kind, to avert his attack. He had just come from an unsuccessful attempt upon the northern frontier of Babylon, and at first it appeared as if he were to find no better fortune on the western border of Lydia. In spite of his superior numbers, the Lydian army kept the ground on which he met them in battle. But Crœsus, thinking that the war was over for the season, fell back soon afterwards on Sardis, and Cyrus, following him up by forced marches, surprised him under the walls of the city, routed the famous Lydian cavalry by the novel terror of his camels, and after a siege of fourteen days sent a few soldiers to scale a side of the citadel too steep to be guarded by the defenders; and so Sardis, its king and its empire, lay at his feet. This Lydian campaign of Cyrus, which is related by Herodotus, is worth noting here for the light it throws on the character of the man, whom according to our prophecy, God chose to be His chief instrument in that generation. If his turning back from Babylonia, eight years before he was granted an easy entrance to her capital, shows how patiently Cyrus could wait upon fortune, his quick march upon Sardis is the brilliant evidence that when fortune showed the way, she found this Persian an obedient and punctual follower. The Lydian campaign forms as good an illustration as we shall find of these texts of our prophet: _He pursueth them, he passeth in safety; by a way he_ almost _treads not with his feet. He cometh upon satraps as on mortar, and as the potter treadeth upon clay_ (xli. 3, 25). _I have
