foster-brother of Antiochus Epiphanes (1 Macc. vii. 14, &c., 55, 2 Macc. ix. 29.), was a Phrygian by birth, and very much in Antiochus's favour. This prince made him governor of Jerusalem (2 Macc. viii. 8, v. 22.) where he committed many outrages upon the Jews, to force them to forsake their religion. Seeing that Apollonius and Seron were defeated by Judas Maccabeus, he sent for new succours to Ptolemy governor of Coelo-Syria, who sent him Gorgias and Nicanor with a powerful army. Some time after, Antiochus going beyond the Euphrates, to extort money from the people, Philip went along with him; and Antiochus finding himself near his end (1 Macc. vi. 14.) made him regent of the kingdom, put his diadem into his hands, his royal cloak, and his ring, that he might render them to his son the young Antiochus Eupator. But Lyrias having taken possession of the government in the name of young Eupator, who was but a child, Philip not being able to cope with him, durst not return into Syria; but he went into Egypt, carrying the body of Epiphanes along with him, there to implore affiance from Ptolemy Philometor against Lyrias the usurper of the government of Syria. The year following, while Lyrias was busy in the war carrying on against the Jews, Philip got into Syria, and took possession of Antioch; but Lyrias returning into the country, with great diligence, retook Antioch, and put Philip to death, who was taken in the city.
