Josephus, Jewish Antiquities 13:354
Cleopatra III (e.g. 142 – 101) appointed two Jews, Helkias and Ananias, as commanders-in-chief of her army. They served their queen well, although in one remarkable episode they counseled her not to invade the territory of the Jewish King Alexander Jannaeus (e.g. 103 – 76 B.C.E.) because “an injustice done to this man will make all us Jews your enemies.”
