GERRENIANS, GERRHENIANS gûr rĕn’ e ənz (Γερρηνων, A Γεννηρων). Lysias, in fighting against Judas Maccabeus in 162 b.c., was forced to return to Syria because of a deterioration of affairs in Antioch. Before going N he made peace with the Jews and left Hegemonides in command from Ptolemais to the (land/city) of the Gerrenians (

The name indicates the southern limit of the territory assigned by Antiochus Eupator to the government of Judas Maccabeus when he "left Hegemonides governor from Ptolemais even unto the Gerrenians" (2 Macc 13:24, the"Gerrhenians"). It is not easy to say exactly who the Gerrenians were. They were wrongly associated by Grotius with the town Gerrha, and are with more probability connected with the ancient city of Gerar, Southeast of Gaza. One manuscript reads Gerarenon, which could easily be corrupted into Gerrenon, and would place the government of Hegemonides between Ptolemais and Gerar.
