1 The men of Ephraim were called out, and they crossed over to Zaphon. They said to Jephthah, “Why did you go to fight with the Ammonites without calling us to go with you? We will burn your house on top of you.”
2 Jephthah answered them, “My soldiers and I were engaged in a contest with the Ammonites. They were pressing us hard, and I cried out to you, but you did not come to save me from their power.
3 When I saw that you were not coming to save me, I took my life in my own hand and crossed over against the Ammonites, and the Lord delivered them into my power. Why, then, should you come up against me this day to fight with me?”
4 Then Jephthah gathered together all the men of Gilead and fought against Ephraim. The men of Gilead defeated Ephraim,
5 and Gilead seized the fords of the Jordan against Ephraim. When any of the fleeing Ephraimites said, “Let me pass,” the men of Gilead would say to him, “Are you an Ephraimite?” If he answered, “No!”
6 they would ask him to say “Shibboleth.” If he said “Sibboleth,” not pronouncing it exactly right, they would seize him and kill him at the fords of the Jordan. Forty-two thousand Ephraimites fell at that time.
