Shofetim 12:4-6 Orthodox Jewish Bible (OJB)
4 Then Yiftach gathered together all the Anshei Gil‘ad, and fought with Ephrayim; and the anshei Gil‘ad struck down Ephrayim, because they said, Ye Gilead are fugitives of Ephrayim among the Ephrayim, and among the Menasheh.
5 And the Gilead took the fords of the Yarden before the Ephrayim; and it was so, that when those Ephrayim which were escaped said, Let me cross over; that the anshei Gil‘ad said unto him, Art thou an Ephrati? If he said, No,
6 Then said they unto him, Say now Shibbolet; and he said Sibbolet, for he could not pronounce it right. Then they took him, and slaughtered him at the fords of the Yarden; and there fell at that time of the Ephrayim forty and two thousand.
