Flavius Josephus, Antiquities of the Jews

[36] WHEN king Hezekiah had survived the interval of time already mentioned, and had dwelt all that time in peace, he died, having completed fifty-four years of his life, and reigned twenty-nine. But when his son Manasseh, whose mother's name was Hephzibah, of Jerusalem, had taken the kingdom, he departed from the conduct of his father, and fell into a course of life quite contrary thereto, and showed himself in his manners most wicked in all respects, and omitted no sort of impiety, but imitated those transgressions of the Israelites, by the commission of which against God they had been destroyed; for he was so hardy as to defile the temple of God, and the city, and the whole country; for, by setting out from a contempt of God, he barbarously slew all the righteous men that were among the Hebrews; nor would he spare the prophets, for he every day slew some of them, till Jerusalem was overflown with blood. So God was angry at these proceedings, and sent prophets to the king, and to the multitude, by whom he threatened the very same calamities to them which their brethren the Israelites, upon the like affronts offered to God, were now under. But these men would not believe their words, by which belief they might have reaped the advantage of escaping all those miseries; yet did they in earnest learn that what the prophets had told them was true.
