“Then Jephthah gathered together all the men of Gilead, and fought with Ephraim: and the men of Gilead smote Ephraim, because they said, Ye Gileadites are fugitives of Ephraim among the Ephraimites, and among the Manassites.”
King James Version (KJV)
12:4 Ye Gileadites - These words are a contemptuous expression of the Ephraimites concerning the Gileadites, whom they call fugitives of Ephraim; the word Ephraim being here taken largely, as it comprehends the other neighbouring tribes, of which Ephraim was the chief; and especially their brethren of Manasseh, who lived next to them, and were descended from the same father, Joseph. By Gileadites here they seem principally to mean the Manassites beyond Jordan, who dwelt in Gilead. And although other Gileadites were joined with them, yet they vent their passion against these; principally, because they envied them most; as having had a chief hand in the victory. These they opprobriously call fugitives, that is, such as had deserted their brethren of Ephraim and Manasseh, planted themselves beyond Jordan, at a distance from their brethren, and were alienated in affection from them.
