The men of Ephraim were gathered together, and passed northward; and they said to Jephthah, Why did you pass over to fight against the children of Ammon, and didn't call us to go with you? we will burn your house on you with fire.
In the battle that followed east of the Jordan, 42,000 Ephraimites (or 42 military units) suffered defeat, a high price for jealousy. The Gileadites stopped those who tried to flee back home at the fords of the Jordan. The Ephraimites’ accent did not permit them to say shibboleth (meaning "ear of corn" or "flowing stream") normally. Similarly during World War II, the Nazis identified Russian Jews by the way they pronounced "kookoorooza," the Russian word for corn. [Note: Wolf, p. 458.] In this way the Gileadite soldiers identified the fleeing Ephraimites.
