Gerrenians
Hastings' Dictionary of the Bible [1]
Gerrenians ( 2Ma 13:24 ). The true reading and the people intended are both uncertain. The analogy of 1Ma 11:59 suggests some place near the border of Egypt; but Gerrha , between Pelusium and Rhinocolura, was in Egyptian territory. It has been suggested that the reference is to Gerar , an ancient Phil. city S. E. of Gaza. On the other hand, Syr. reads Gazar, i.e . Gezer or Gazara, not far from Lydda (cf. 1Ma 15:28; 1Ma 15:35 ).

ge - rē´ni - anz ( ἕως τῶν Γερρηνῶν , héōs tō̇n Gerrēnō̇n ): 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 Maccabees 13:24 , the King James Version "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 Gerarēnōn , which could easily be corrupted into Gerrēnōn , and would place the government of Hegemonides between Ptolemais and Gerar.
