And now approached the greatest crisis that had yet occurred in the history of the city. Hezekiah reformed the worship and declined to be a dependent on Assyria. Sennacherib had succeeded Tiglath Pileser, and the dreaded Assyrian army approached. Hezekiah stopped the springs round Jerusalem, repaired the walls of the city, breaking down houses to get the material--even raised the wall in some places up to the towers; and built a second wall at some exposed part, and strengthened Millo (2 Kings xx. 20; 2 Chron. xxxii. 3-5, 30; Isaiah xxii. 10). On this occasion it would appear that the city escaped, but at the cost of the treasures of the palace and the temple. B.C. 700.
In the middle of the long reign of Manasseh Jerusalem was taken by Assur-bani-pal, the grandson of Sennacherib, B.C. 650.
But Manasseh, in the latter part of his reign, sought to repair and strengthen the city. He built a fresh wall, extending “from the west side of Gihon-in-the-valley to the Fish Gate;” and he also continued the works which had been begun at Ophel, and raised the structure to a very great height. B.C. 640.
During the reign of Jehoiakim Jerusalem was visited by Nebuchadnezzar, with the Babylonian army lately victorious over the Egyptians at Carchemish, and it is thought that there must have been a siege, but we have no account of it. Jehoiakim was succeeded by his son Jehoiachin, and hardly had his short reign begun before the terrible army of Babylon reappeared before the city, again commanded by Nebuchadnezzar (2 Kings xxiv). Jehoiachin surrendered, and the city was pillaged. Jehoiachin being carried off to Babylon, his uncle Zedekiah was made king; but he was imprudent enough to seek the help of Pharaoh Hophra of Egypt, and upon this Nebuchadnezzar marched to Jerusalem again and began a regular siege. The walls and houses were battered by rams, and missiles were discharged into the town. After some delays a breach was made in the north wall, and the city suffered all the horrors of assault and sack. Zedekiah had stolen out of the city on the south side, but was pursued and overtaken. The Babylonians burnt the Temple, the palace, and other public buildings, and threw down the city walls. B.C. 577.
