(Challoner) --- They had not all the privileges of wives; (Genesis xxv. 6,) and their children could not claim the inheritance. (Calmet) --- Abimelech means, "my (Haydock) father king;" alluding to the dignity of Gedeon; or perhaps the mother imposed this name, hoping that her son would obtain the highest honours. Josephus calls her Druma. She dwelt at Sichem, to which place the judge of Israel often resorted, though his usual residence was at Ephra. This son of theirs is included among the 70.
