What does Judges 12:5 mean?
The exact reasons for this conflict between the men of Ephraim and the people of Gilead are hard to understand. Jephthah led Gilead to defeat the Ammonites (Judges 11:32–33). After the battle, armed Ephraimites marched into Gilead territory and began making threats and accusations (Judges 12:1–4). They might have been angry they were not called sooner to the war—though they had ample time to help (Judges 10:17–18; 11:4)—but are more likely looking to capture territory. Regardless of motives, it quickly becomes clear that Ephraim greatly miscalculated their chances of winning.Jephthah takes the threat from Ephraim seriously enough to gather his Gilead fighters and attack the invading forces. Gilead strikes Ephraim hard and completely subdues them. Then Gilead's fighters take control of the fords of the Jordan River (Judges 3:28) over which the men of Ephraim could have escaped back into their own territory. As the scattered Ephraimite soldiers arrive at the fords to retreat, the men of Gilead kill the trespasser one-by-one rather than letting them go. They even devise a test to know if a man is from Ephraim or from Gilead (Judges 12:6).
