International Standard Bible Encyclopedia (1915)

ge-ne’-us, ge-ne’-us (Gennaios): Father of Apollonius, one of the Syrian generals who troubled the Jews while Lysias was governor for Antiochus Eupator (2 Macc 12:2). The description is added to distinguish the Apollonius here mentioned from several others of the same name. See Apollonius. There is no need with Luther to take the name simply as an adjective "des edlen Apollonius." The name occurs elsewhere as a proper name.
