1 The men of Ephraim prepared for battle; they crossed the River Jordan to Zaphon and said to Jephthah, “Why did you cross the border to fight the Ammonites without calling us to go with you? We'll burn the house down over your head!”
2 But Jephthah said to them, “My people and I had a serious quarrel with the Ammonites. I did call you, but you would not rescue me from them.
3 When I saw that you were not going to, I risked my life and crossed the border to fight them, and the Lord gave me victory over them. So why are you coming to fight me now?”
4 Then Jephthah brought all the men of Gilead together, fought the men of Ephraim and defeated them. (The Ephraimites had said, “You Gileadites in Ephraim and Manasseh, you are deserters from Ephraim!”)
5 In order to keep the Ephraimites from escaping, the Gileadites captured the places where the Jordan could be crossed. When any Ephraimite who was trying to escape asked permission to cross, the men of Gilead would ask, “Are you an Ephraimite?” If he said, “No,”
6 they would tell him to say “Shibboleth”. But he would say “Sibboleth”, because he could not pronounce it correctly. Then they would seize him and kill him there at one of the crossings of the Jordan. At that time 42,000 of the Ephraimites were killed.
