Judges 12:1-3

It looks like there's a slight misunderstanding here between the Gileadites and the Ephraimites. On one hand, the Ephraimites say they weren't called by the Gileadites to help join in the fight. On the other, the Gileadites leader Jephthah says that they did call the Ephraimites for help. It's pretty mind-boggling to think that 42,000 lives could have been spared if someone had just paid something equivalent to a "phone bill."
