After receiving his crown from Nebuchadnezzar, Zedekiah continued for eight years to play the part of a faithful vassal. At length, however, in the ninth year, he fancied he saw a way to independence. A young and enterprising monarch, Uaphris—the Apries of Herodotus—had recently mounted the Egyptian throne. If the alliance of this prince could be secured, there was, Zedekiah thought, a reasonable hope that the yoke of Babylon might be thrown off and Hebrew autonomy re-established. The infatuated monarch did not see that, do what he would, his country had no more than a choice of masters, that by the laws of political attraction Judaea must gravitate to one or other of the two great states between which it had the misfortune of lying. Hoping to free his country, he sent ambassadors to Uaphris, who were to conclude a treaty and demand the assistance of a powerful contingent, composed of both foot and horse. Uaphris received the overture favorably; and Zedekiah at once revolted from Babylon, and made preparations to defend himself with vigor. It was not long before the Babylonians arrived. Determined to crush the daring state, which, weak as it was, had yet ventured to revolt against him now for the fourth time, Nebuchadnezzar came in person, “he and all his host,” against Jerusalem, and after overcoming and pillaging the open country, “built forts” and besieged the city. Uaphris, upon this, learning the danger of his ally, marched out of Egypt to his relief; and the Babylonian army, receiving intelligence of his approach, raised the siege and proceeded in quest of their new enemy. According to Josephus a battle was fought, in which the Egyptians were defeated; but it is perhaps more probable that they avoided an engagement by a precipitate retreat into their own country. At any rate the attempt effectually to relieve Jerusalem failed. After a brief interval the siege was renewed; a complete blockade was established; and in a year and a half from the time of the second investment, the city fell.

Nebuchadnezzar had not waited to witness this success of his arms. The siege of Tyre was still being pressed at the date of the second investment of Jerusalem, and the Chaldaean monarch had perhaps thought that his presence on the borders of Phoenicia was necessary to animate his troops in that quarter. If this was his motive in withdrawing from the Jewish capital, the event would seem to have shown that he judged wisely. Tyre, if it fell at the end of its thirteen years’ siege, must have been taken in the very year which followed the capture of Jerusalem, B.C. 585. We may suppose that Nebuchadnezzar, when he quitted Jerusalem and took up his abode at Eiblah in the Coele-Syrian valley, turned his main attention to the great Phoenician city, and made arrangements which caused its capture in the ensuing year.

The recovery of these two important cities secured to the Babylonian monarch the quiet possession thenceforth of Syria and Palestine. But still he had not as yet inflicted any chastisement upon Egypt; though policy, no less than honor, required that the aggressions of this audacious power should be punished. If we may believe Josephus, however, the day of vengeance was not very long delayed. Within four years of the fall of Tyre, B.C. 581, Nebuchadnezzar, he tells us, invaded Egypt, put Uaphris, the monarch who had succored Zedekiah, to death, and placed a creature of his own upon the throne. Egyptian history, it is true, forbids our accepting this statement as correct in all its particulars. Uaphris appears certainly to have reigned at least as late as B.C. 569, and according to Herodotus, he was put to death, not by a foreign invader, but by a rebellious subject. Perhaps we may best harmonize the conflicting statements on the subject by supposing that Josephus has confounded two distinct invasions of Egypt, one made by Nebuchadnezzar in his twenty-third year, B.C. 581, which had no very important consequences, and the other eleven years later, B.C. 570, which terminated in the deposition of Uaphris, and the establishment on the throne of a new king, Amasis, who received a nominal royalty from Chaldaean monarch.

Such—as far as they are known—were the military exploits of this great king. He defeated Neco, recovered Syria, crushed rebellion in Judaea, took Tyre, and humiliated Egypt. According to some writers his successes did not stop here. Megasthenes made him subdue most of Africa, and thence pass over into Spain and conquer the Iberians. He even went further, and declared that, on his return from these regions, he settled his Iberian captives on the shores of the Euxine in the country between Armenia and the Caucasus! Thus Nebuchadnezzar was made to reign over an empire extending from the Atlantic to the Caspian, and from the Caucasus to the Great Sahara.

The victories of Nebuchadnezzar were not without an effect on his home administration and on the construction of the vast works with which his name is inseparably associated. It was through them that he obtained that enormous command of “naked human strength” which enabled him, without undue oppression of his own people, to carry out on the grandest scale his schemes for at once beautifying and benefiting his kingdom. From the time when he first took the field at the head of an army he adopted the Assyrian system of forcibly removing almost the whole population of a conquered country, and planting it in a distant part of his dominions. Crowds of captives—the produce of his various wars—Jews, Egyptians, Phoenicians, Syrians, Ammonites, Moabites, were settled in various parts of Mesopotamia, more especially about Babylon. From these unfortunates forced labor was as a matter of course required; and it seems to have been chiefly, if not solely, by their exertions that the magnificent series of great works was accomplished, which formed the special glory of the Fourth Monarchy.

The chief works expressly ascribed to Nebuchadnezzar by the ancient writers are the following: He built the great wall of Babylon, which, according to the lowest estimate, must have contained more than 500,000,000 square feet of solid masonry, and must have required three or four times that number of bricks. He constructed a new and magnificent palace in the neighborhood of the ancient residence of the kings. He made the celebrated “Hanging Garden” for the gratification of his wife, Amyitis. He repaired and beautified the great temple of Belus at Babylon. He dug the huge reservoir near Sippara, said to have been 140 miles in circumference, and 180 feet deep, furnishing it with flood-gates, through which its water could be drawn off for purposes of irrigation. He constructed a number of canals, among them the Nahr Malcha or “Royal River,” a broad and deep channel which connected the Euphrates with the Tigris. He built quays and breakwaters along the shores of the Persian Gulf, and he at the same time founded the city of Diridotis or Teredon in the vicinity of that sea.

To these constructions may be added, on the authority either of Nebuchadnezzar’s own inscriptions or of the existing remains, the Birs-i-Nimrud, or great temple of Nebo at Bor-sippa; a vast reservoir in Babylon itself, called the Yapur-Shapu; an extensive embankment along the course of the Tigris, near Baghdad; and almost innumerable temples, walls, and other public buildings at Cutha, Sippara, Borsippa, Babylon, Chilmad, Bit-Digla, etc. The indefatigable monarch seems to have either rebuilt, or at least repaired, almost every city and temple throughout the entire country. There are said to be at least a hundred sites in the tract immediately about Babylon, which give evidence, by inscribed bricks bearing his legend, of the marvellous activity and energy of this king.

We may suspect that among the constructions of Nebuchadnezzar was another great work, a work second in utility to none of those above mentioned, and requiring for its completion an enormous amount of labor. This is the canal called by the Arabs the Kerek Saideh, or canal of Saideh, which they ascribe to a wife of Nebuchadnezzar, a cutting 400 miles in length, which commenced at Hit on the Euphrates, and was carried along the extreme western edge of the alluvium close to the Arabian frontier, finally falling into the sea at the head of the Bubian creek, about twenty miles to the west of the Shat el-Arab. The traces of this canal which still remain indicate a work of such magnitude and difficulty that we can scarcely ascribe it with probability to any monarch who has held the country since Nebuchadnezzar.

The Pallacopas, or canal of Opa (Palga Opa), which left the Euphrates at Sippara (Mosaib) and ran into a great lake in the neighborhood of Borsippa, whence the lands in the neighborhood were irrigated, may also have been one of Nebuchadnezzar’s constructions. It was an old canal, much out of repair, in the time of Alexander, and was certainly the work, not of the Persian conquerors, but of some native monarch anterior to Cyrus. The Arabs, who call it the Nahr Abba, regard it as the oldest canal in the country.

Some glimpses into the private life and personal character of Nebuchadnezzar are afforded us by certain of the Old Testament writers. We see him in the Book of Daniel at the head of a magnificent Court, surrounded by “princes, governors, and captains, judges, treasurers, councillors, and sheriffs;” waited on by eunuchs selected with the greatest care, “well-favored” and carefully educated; attended, whenever he requires it, by a multitude of astrologers and other “wise men,” who seek to interpret to him the will of Heaven. He is an absolute monarch, disposing with a word of the lives and properties of his subjects, even the highest. All offices are in his gift. He can raise a foreigner to the second place in the kingdom, and even set him over the entire priestly order. His wealth is enormous, for he makes of pure gold an image, or obelisk, ninety feet high and nine feet broad. He is religious after a sort, but wavers in his faith, sometimes acknowledging the God of the Jews as the only real deity, sometimes relapsing into an idolatrous worship, and forcing all his subjects to follow his example. Even then, however, his polytheism is of a kind which admits of a special devotion to a particular deity, who is called emphatically “his god.” In temper he is hasty and violent, but not obstinate; his fierce resolves are taken suddenly and as suddenly repented of; he is moreover capable of bursts of gratitude and devotion, no less than of accesses of fury; like most Orientals, he is vainglorious but he can humble himself before the chastening hand of the Almighty; in his better moods he shows a spirit astonishing in one of his country and time—a spirit of real piety, self-condemnation, and self-abasement, which renders him one of the most remarkable characters in Scripture.
