Josephus & the 2 Books of Ezekiel

Moreover, this prophet denounced beforehand the sad calamities that were coming upon the city. He also left behind him in writing a description of that destruction of our nation which has lately happened in our days, and the taking of Babylon; nor was he the only prophet who delivered such predictions beforehand to the multitude, but so did Ezekiel also, who was the first person that wrote, and left behind him in writing two books concerning these events. (Emphasis mine)

Now these two prophets were priests by birth, but of them Jeremiah dwelt in Jerusalem, from the thirteenth year of the reign of Josiah, until the city and temple were utterly destroyed. However, as to what befell this prophet, we will relate it in its proper place.
