Flavius Josephus, Antiquities of the Jews
William Whiston, A.M., Ed.

[116] Now in the ninth year of the reign of Zedekiah, on the tenth day of the tenth month, the king of Babylon made a second expedition against Jerusalem, and lay before it eighteen months, and besieged it with the utmost application. There came upon them also two of the greatest calamities at the same time that Jerusalem was besieged, a famine and a pestilential distemper, and made great havoc of them. And though the prophet Jeremiah was in prison, he did not rest, but cried out, and proclaimed aloud, and exhorted the multitude to open their gates, and admit the king of Babylon, for that if they did so, they should be preserved, and their whole families; but if they did not so, they should be destroyed; and he foretold, that if any one staid in the city, he should certainly perish by one of these ways, - either be consumed by the famine, or slain by the enemy's sword; but that if he would flee to the enemy, he should escape death. Yet did not these rulers who heard believe him, even when they were in the midst of their sore calamities; but they came to the king, and in their anger informed him what Jeremiah had said, and accused him, and complained of the prophet as of a madman, and one that disheartened their minds, and by the denunciation of miseries weakened the alacrity of the multitude, who were otherwise ready to expose themselves to dangers for him, and for their country, while he, in a way of threatening, warned them to flee to the enemy, and told them that the city should certainly be taken, and be utterly destroyed.
