Judges 12:4-6 Easy-to-Read Version (ERV)
4 Then Jephthah called the men of Gilead together. They fought against the men from the tribe of Ephraim because they had insulted the men of Gilead. They had said, “You men of Gilead are nothing but survivors of the men of Ephraim. Part of you belongs to Ephraim, and part of you belongs to Manasseh.” The men of Gilead defeated the men of Ephraim.
5 The men of Gilead captured the places where people cross the Jordan River. Those places led to the country of Ephraim. Any time a survivor from Ephraim came to the river and said, “Let me cross,” the men of Gilead would ask him, “Are you from Ephraim?” If he said, “No,” 6 they would say, “Say the word ‘Shibboleth.’” The men of Ephraim could not say that word correctly. They pronounced the word “Sibboleth.” So if the man said, “Sibboleth,” then the men of Gilead knew he was from Ephraim. So they would kill him at the crossing place. They killed 42,000 men from Ephraim.
