[242] Now Antiochus, upon the agreeable situation of the affairs of his kingdom, resolved to make an expedition against Egypt, both because he had a desire to gain it, and because he contemned the son of Ptolemy, as now weak, and not yet of abilities to manage affairs of such consequence; so he came with great forces to Pelusium, and circumvented Ptolemy Philometor by treachery, and seized upon Egypt. He then came to the places about Memphis; and when he had taken them, he made haste to Alexandria, in hopes of taking it by siege, and of subduing Ptolemy, who reigned there. But he was driven not only from Alexandria, but out of all Egypt, by the declaration of the Romans, who charged him to let that country alone; according as I have elsewhere formerly declared. I will now give a particular account of what concerns this king, how he subdued Judea and the temple; for in my former work I mentioned those things very briefly, and have therefore now thought it necessary to go over that history again, and that with great accuracy.
