The remnant that was left, the small realm of Judah, took warning, and turned to God with all their heart, and therefore were protected; but they had much to suffer. Sargon's son, Sennacherib, was a proud and ambitious monarch, who used his Israelite captives in building up the walls of Nineveh, and making the most magnificent of all the palaces there, eight acres in size, and covered with inscriptions. He invaded Judea, took forty-six cities, and besieged Jerusalem, raising a mound to overtop the walls; but on receiving large gifts from Hezekiah, he returned to his own land. At Babylon a prince named Merodach Baladan had set himself up against Sennacherib, and sought the friendship of Hezekiah. When the good King of Judah recovered from his illness by a miracle, the sign of which was, that the sun seemed to retreat in his course, it probably won the attention of the Chaldeans, who were great star-gazers; and Merodach Baladan sent messengers to compliment the king, whose favour with Heaven had thus been shown to all the earth. For once Hezekiah erred, and was so much uplifted, as to display his treasure and his new-born son in ostentation. Isaiah rebuked him, telling him that his children should be slaves in the hands of the very nation who had heard his boast. He meekly submitted, thankful that there should be peace and truth in his days. Soon after, Babylon was reduced by Sennacherib, and Merodach Baladan driven into exile. In the latter years of his reign, Sennacherib undertook an expedition into Egypt, and on his way sent a blasphemous message by his servant, Rabshakeh, to summon Hezekiah to submit, and warning him and his people, that their God could no more protect them than the gods of the conquered nations had saved their worshippers. In answer to the prayer of Hezekiah, came, by the mouth of Isaiah, an assurance that the boaster who insulted the living God, was only an instrument in His Hands, unable to go one step against His will. Not one arrow should he shoot against the holy city, but he should hear a rumour, a blast should be sent on him, and he should fall by the sword in his own land.
