Judges 12:4-6 New American Bible (Revised Edition) (NABRE)
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.”[a] 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.
